An interactive component can participate in tabbing and other kinds of keyboard focus manipulation, accept low-level events like keyboard and mouse input, and be disabled so that it does not receive keyboard and mouse input. This is in contrast to noninteractive components, like Label and ProgressBar, which simply display contents and are not manipulated by the user.
The UIComponent class is not used as an MXML tag, but is used as a base class for other classes.

baseline | property |
baseline:Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
For components, this layout constraint property is a
facade on top of the similarly-named style. To set
the property to its default value of undefined,
use the @Clear() directive in MXML or the undefined
value in ActionScript code. For example, in MXML code,
baseline.s2="@Clear()" unsets the baseline
constraint in state s2. Or in ActionScript code,
button.baseline = undefined unsets the baseline
constraint on button.
By default the anchor target is the top edge of the container's content area. In layouts with advanced constraints, the target can be a constraint row.
Setting the property to a number or to a numerical string like "10" specifies use of the default anchor target.
To specify an anchor target, set the property value to a string in the format: "anchorTargetName:value". For example, "row1:10".

designLayer | property |
designLayer:DesignLayer| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Specifies the optional DesignLayer instance associated with this visual element.
When a DesignLayer is assigned, a visual element must consider the visibility and alpha of its parent layer when ultimately committing its own effective visibility or alpha to its backing DisplayObject (if applicable).
A visual element must listen for layerPropertyChange
notifications from the associated layer parent. When the
effectiveAlpha or effectiveVisibility of the
layer changes, the element must then compute its own effective visibility
(or alpha) and apply it accordingly.
This property should not be set within MXML directly.
The designLayer property is not used for z-order control,
please see depth.

doubleClickEnabled:Boolean[override] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Specifies whether the UIComponent object receives doubleClick events.
The default value is false, which means that the UIComponent object
does not receive doubleClick events.
The mouseEnabled property must also be set to true,
its default value, for the object to receive doubleClick events.
The default value is false.
Implementation

enabled:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Whether the component can accept user interaction. After setting the enabled
property to false, some components still respond to mouse interactions such
as mouseOver. As a result, to fully disable UIComponents,
you should also set the value of the mouseEnabled property to false.
If you set the enabled property to false
for a container, Flex dims the color of the container and of all
of its children, and blocks user input to the container
and to all of its children.
This property can be used as the source for data binding. When this property is modified, it dispatches the enabledChanged event.
Implementation

errorString:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The text that displayed by a component's error tip when a component is monitored by a Validator and validation fails.
You can use the errorString property to show a
validation error for a component, without actually using a validator class.
When you write a String value to the errorString property,
Flex draws a red border around the component to indicate the validation error,
and the String appears in a tooltip as the validation error message when you move
the mouse over the component, just as if a validator detected a validation error.
To clear the validation error, write an empty String, "",
to the errorString property.
Note that writing a value to the errorString property
does not trigger the valid or invalid events; it only changes the border
color and displays the validation error message.
This property can be used as the source for data binding. When this property is modified, it dispatches the errorStringChanged event.

explicitHeight:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Number that specifies the explicit height of the component, in pixels, in the component's coordinates.
This value is used by the container in calculating
the size and position of the component.
It is not used by the component itself in determining
its default size.
Thus this property may not have any effect if parented by
Container, or containers that don't factor in
this property.
Because the value is in component coordinates,
the true explicitHeight with respect to its parent
is affected by the scaleY property.
Setting the height property also sets this property to
the specified height value.
This property can be used as the source for data binding. When this property is modified, it dispatches the explicitHeightChanged event.
Implementation

explicitMaxHeight:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The maximum recommended height of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels.
Application developers typically do not set the explicitMaxHeight property. Instead, they set the value of the maxHeight property, which sets the explicitMaxHeight property. The value of maxHeight does not change.
At layout time, if maxHeight was explicitly set by the application developer, then the value of explicitMaxHeight is used. Otherwise, the default value for maxHeight is used.
This value is used by the container in calculating
the size and position of the component.
It is not used by the component itself in determining
its default size.
Thus this property may not have any effect if parented by
Container, or containers that don't factor in
this property.
Because the value is in component coordinates,
the true maxHeight with respect to its parent
is affected by the scaleY property.
Some components have no theoretical limit to their height.
In those cases their maxHeight is set to
UIComponent.DEFAULT_MAX_HEIGHT.
The default value is NaN.
This property can be used as the source for data binding. When this property is modified, it dispatches the explicitMaxHeightChanged event.

explicitMaxWidth:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The maximum recommended width of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels.
Application developers typically do not set the explicitMaxWidth property. Instead, they set the value of the maxWidth property, which sets the explicitMaxWidth property. The value of maxWidth does not change.
At layout time, if maxWidth was explicitly set by the application developer, then the value of explicitMaxWidth is used. Otherwise, the default value for maxWidth is used.
This value is used by the container in calculating
the size and position of the component.
It is not used by the component itself in determining
its default size.
Thus this property may not have any effect if parented by
Container, or containers that don't factor in
this property.
Because the value is in component coordinates,
the true maxWidth with respect to its parent
is affected by the scaleX property.
Some components have no theoretical limit to their width.
In those cases their maxWidth is set to

| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The minimum recommended height of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels.
Application developers typically do not set the explicitMinHeight property. Instead, they set the value of the minHeight property, which sets the explicitMinHeight property. The value of minHeight does not change.
At layout time, if minHeight was explicitly set by the application developer, then the value of explicitMinHeight is used. Otherwise, the value of measuredMinHeight is used.
This value is used by the container in calculating
the size and position of the component.
It is not used by the component itself in determining
its default size.
Thus this property may not have any effect if parented by
Container, or containers that don't factor in
this property.
Because the value is in component coordinates,
the true minHeight with respect to its parent
is affected by the scaleY property.
The default value is NaN.

The minimum recommended width of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels.
Application developers typically do not set the explicitMinWidth property. Instead, they set the value of the minWidth property, which sets the explicitMinWidth property. The value of minWidth does not change.
At layout time, if minWidth was explicitly set by the application developer, then the value of explicitMinWidth is used. Otherwise, the value of measuredMinWidth is used.
This value is used by the container in calculating
the size and position of the component.
It is not used by the component itself in determining
its default size.
Thus this property may not have any effect if parented by
Container, or containers that don't factor in
this property.
Because the value is in component coordinates,
the true minWidth with respect to its parent

Number that specifies the explicit width of the component, in pixels, in the component's coordinates.
This value is used by the container in calculating
the size and position of the component.
It is not used by the component itself in determining
its default size.
Thus this property may not have any effect if parented by
Container, or containers that don't factor in
this property.
Because the value is in component coordinates,
the true explicitWidth with respect to its parent

focusEnabled:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Indicates whether the component can receive focus when tabbed to.
You can set focusEnabled to false
when a UIComponent is used as a subcomponent of another component
so that the outer component becomes the focusable entity.
If this property is false, focus is transferred to
the first parent that has focusEnable
set to true.
The default value is true, except for the
spark.components.Scroller component.
For that component, the default value is false.

hasFocusableChildren | property |
hasFocusableChildren:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
A flag that indicates whether child objects can receive focus.
Note: This property is similar to the tabChildren property
used by Flash Player.
Use the hasFocusableChildren property with Flex applications.
Do not use the tabChildren property.
This property is usually false because most components
either receive focus themselves or delegate focus to a single
internal sub-component and appear as if the component has
received focus.
For example, a TextInput control contains a focusable
child RichEditableText control, but while the RichEditableText
sub-component actually receives focus, it appears as if the
TextInput has focus. TextInput sets hasFocusableChildren
to false because TextInput is considered the
component that has focus. Its internal structure is an
abstraction.
Usually only navigator components, such as TabNavigator and
Accordion, have this flag set to true because they
receive focus on Tab but focus goes to components in the child
containers on further Tabs.
The default value is false, except for the
spark.components.Scroller component.
For that component, the default value is true.
This property can be used as the source for data binding. When this property is modified, it dispatches the hasFocusableChildrenChange event.

hasLayoutMatrix3D:Boolean [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Contains true if the element has 3D Matrix.
Use hasLayoutMatrix3D instead of calling and examining the
return value of getLayoutMatrix3D() because that method returns a valid
matrix even when the element is in 2D.
Implementation
public function get hasLayoutMatrix3D():Booleanheight | property |
height:Number[override] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Number that specifies the height of the component, in pixels, in the parent's coordinates. The default value is 0, but this property contains the actual component height after Flex completes sizing the components in your application.
Note: You can specify a percentage value in the MXML
height attribute, such as height="100%",
but you cannot use a percentage value for the height
property in ActionScript;
use the percentHeight property instead.
Setting this property causes a resize event to be dispatched.
See the resize event for details on when
this event is dispatched.
This property can be used as the source for data binding. When this property is modified, it dispatches the heightChanged event.

horizontalCenter | property |
horizontalCenter:Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
For components, this layout constraint property is a
facade on top of the similarly-named style. To set
the property to its default value of undefined,
use the @Clear() directive in MXML or the undefined
value in ActionScript code. For example, in MXML code,
horizontalCenter.s2="@Clear()" unsets the
horizontalCenter
constraint in state s2. Or in ActionScript code,
button.horizontalCenter = undefined unsets the
horizontalCenter constraint on button.
The default anchor target is the container itself.
In layouts with advanced constraints, the anchor target can be a constraint column. Then the content area is the space between the preceding column (or container side) and the target column.
Setting the property to a number or to a numerical string like "10" specifies use of the default anchor target.
To specify an anchor target, set the property value to a string in the format "constraintColumnId:value". For example, "col1:10".
Implementation

id:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
ID of the component. This value becomes the instance name of the object and should not contain any white space or special characters. Each component throughout an application should have a unique id.
If your application is going to be tested by third party tools, give each component a meaningful id. Testing tools use ids to represent the control in their scripts and having a meaningful name can make scripts more readable. For example, set the value of a button to submit_button rather than b1 or button1.

If true, the object is included in its parent container's
layout and is sized and positioned by its parent container as per its layout rules.
If false, the object size and position are not affected by its parent container's
layout.
The default value is true.
This property can be used as the source for data binding. When this property is modified, it dispatches the includeInLayoutChanged event.

The beginning of this component's chain of inheriting styles.
The getStyle() method simply accesses
inheritingStyles[styleName] to search the entire
prototype-linked chain.
This object is set up by initProtoChain().
Developers typically never need to access this property directly.

layoutMatrix3D:Matrix3D [write-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
The transform matrix that is used to calculate a component's layout
relative to its siblings. This matrix is defined by the component's
3D properties (which include the 2D properties such as x,
y, rotation, scaleX,
scaleY, transformX, and
transformY, as well as rotationX,
rotationY, scaleZ, z, and
transformZ.
Most components do not have any 3D transform properties set on them.
This layout matrix is combined with the values of the
postLayoutTransformOffsets property to determine the
component's final, computed matrix.

left | property |
left:Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
For components, this layout constraint property is a
facade on top of the similarly-named style. To set
a state-specific value of the property in MXML to its default
value of undefined,
use the @Clear() directive. For example, in MXML code,
left.s2="@Clear()" unsets the left
constraint in state s2. Or in ActionScript code,
button.left = undefined unsets the left
constraint on button.
By default the anchor target is the container's content area. In layouts with advanced constraints, the target can be a constraint column.
Setting the property to a number or to a numerical string like "10" specifies use of the default anchor target.
To specify an anchor target, set the property value to a string in the format "anchorTargetName:value". For example, "col1:10".

maintainProjectionCenter:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |

maxHeight:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The maximum recommended height of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels. The default value of this property is set by the component developer.
The component developer uses this property to set an upper limit on the height of the component.
If the application developer overrides the default value of maxHeight, the new value is stored in explicitMaxHeight. The default value of maxHeight does not change. As a result, at layout time, if maxHeight was explicitly set by the application developer, then the value of explicitMaxHeight is used for the component's maximum recommended height. If maxHeight is not set explicitly by the user, then the default value is used.
This value is used by the container in calculating
the size and position of the component.
It is not used by the component itself in determining
its default size.
Thus this property may not have any effect if parented by
Container, or containers that don't factor in
this property.
Because the value is in component coordinates,
the true maxHeight with respect to its parent
is affected by the scaleY property.
Some components have no theoretical limit to their height.
In those cases their maxHeight is set to
UIComponent.DEFAULT_MAX_HEIGHT.
The default value is 10000.
This property can be used as the source for data binding. When this property is modified, it dispatches the explicitMaxHeightChanged event.

The maximum recommended width of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels. The default value of this property is set by the component developer.
The component developer uses this property to set an upper limit on the width of the component.
If the application developer overrides the default value of maxWidth, the new value is stored in explicitMaxWidth. The default value of maxWidth does not change. As a result, at layout time, if maxWidth was explicitly set by the application developer, then the value of explicitMaxWidth is used for the component's maximum recommended width. If maxWidth is not set explicitly by the user, then the default value is used.
This value is used by the container in calculating
the size and position of the component.
It is not used by the component itself in determining

| Runtime Versions: | Flash Player 9, AIR 1.1 |
The minimum recommended height of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels. The default value depends on the component's implementation.
If the application developer sets the value of minHeight, the new value is stored in explicitMinHeight. The default value of minHeight does not change. As a result, at layout time, if minHeight was explicitly set by the application developer, then the value of explicitMinHeight is used for the component's minimum recommended height. If minHeight is not set explicitly by the application developer, then the value of measuredMinHeight is used.
This value is used by the container in calculating
the size and position of the component.
It is not used by the component itself in determining
its default size.
Thus this property may not have any effect if parented by
Container, or containers that don't factor in
this property.
Because the value is in component coordinates,
the true minHeight with respect to its parent
is affected by the scaleY property.
This property can be used as the source for data binding. When this property is modified, it dispatches the explicitMinHeightChanged event.

The minimum recommended width of the component to be considered by the parent during layout. This value is in the component's coordinates, in pixels. The default value depends on the component's implementation.
If the application developer sets the value of minWidth, the new value is stored in explicitMinWidth. The default value of minWidth does not change. As a result, at layout time, if minWidth was explicitly set by the application developer, then the value of explicitMinWidth is used for the component's minimum recommended width. If minWidth is not set explicitly by the application developer, then the value of measuredMinWidth is used.
This value is used by the container in calculating
the size and position of the component.
It is not used by the component itself in determining
its default size.
Thus this property may not have any effect if parented by
Container, or containers that don't factor in

| Runtime Versions: | Flash Player 9, AIR 1.1 |
Whether you can receive focus when clicked on.
If false, focus is transferred to
the first parent that is mouseFocusEnable
set to true.
For example, you can set this property to false
on a Button control so that you can use the Tab key to move focus
to the control, but not have the control get focus when you click on it.
The default value is true for most subclasses, except the Spark TabBar. In that case, the default is false.
The default value is true.

The beginning of this component's chain of non-inheriting styles.
The getStyle() method simply accesses
nonInheritingStyles[styleName] to search the entire
prototype-linked chain.
This object is set up by initProtoChain().
Developers typically never need to access this property directly.

Implementation
public function get numAutomationChildren():intowner | property |
owner:DisplayObjectContainer| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The owner of this IVisualElement object. By default, it is the parent of this IVisualElement object. However, if this IVisualElement object is a child component that is popped up by its parent, such as the drop-down list of a ComboBox control, the owner is the component that popped up this IVisualElement object.
This property is not managed by Flex, but by each component.
Therefore, if you use the PopUpManger.createPopUp() or
PopUpManger.addPopUp() method to pop up a child component,
you should set the owner property of the child component
to the component that popped it up.
The default value is the value of the parent property.

The parent container or component for this component.
Only visual elements should have a parent property.
Non-visual items should use another property to reference
the object to which they belong.
By convention, non-visual objects use an owner
property to reference the object to which they belong.

parentApplication:Object [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A reference to the Application object that contains this UIComponent instance. This Application object might exist in a SWFLoader control in another Application, and so on, creating a chain of Application objects that can be walked using parentApplication.
The parentApplication property of an Application is never itself;
it is either the Application into which it was loaded or null
(for the top-level Application).
Walking the application chain using the parentApplication
property is similar to walking the document chain using the
parentDocument property.
You can access the top-level application using the
application property of the Application class.
This property can be used as the source for data binding. When this property is modified, it dispatches the initialize event.
Implementation

parentDocument:Object [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A reference to the parent document object for this UIComponent. A document object is a UIComponent at the top of the hierarchy of a Flex application, MXML component, or AS component.
For the Application object, the parentDocument
property is null.
This property is useful in MXML scripts to go up a level
in the chain of document objects.
It can be used to walk this chain using
parentDocument.parentDocument, and so on.
It is typed as Object so that authors can access properties and methods on ancestor document objects without casting.
This property can be used as the source for data binding. When this property is modified, it dispatches the initialize event.
Implementation
public function get parentDocument():ObjectpercentHeight | property |
percentHeight:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Specifies the height of a component as a percentage
of its parent's size. Allowed values are 0-100. The default value is NaN.
Setting the height or explicitHeight properties
resets this property to NaN.
This property returns a numeric value only if the property was previously set; it does not reflect the exact size of the component in percent.
This property is always set to NaN for the UITextField control.
When used with Spark layouts, this property is used to calculate the
height of the component's bounds after scaling and rotation. For example
if the component is rotated at 90 degrees, then specifying
percentHeight will affect the component's width.
This property can be used as the source for data binding. When this property is modified, it dispatches the resize event.

postLayoutTransformOffsets:mx.geom:TransformOffsets| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Defines a set of adjustments that can be applied to the object's transform in a way that is invisible to its parent's layout.
For example, if you want a layout to adjust for an object
that is rotated 90 degrees, set the object's
rotation property. If you want the layout to not
adjust for the object being rotated,
set its postLayoutTransformOffsets.rotationZ property.
Implementation

processedDescriptors:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Set to true after immediate or deferred child creation,
depending on which one happens. For a Container object, it is set
to true at the end of
the createComponentsFromDescriptors() method,
meaning after the Container object creates its children from its child descriptors.
For example, if an Accordion container uses deferred instantiation,
the processedDescriptors property for the second pane of
the Accordion container does not become true until after
the user navigates to that pane and the pane creates its children.
But, if the Accordion had set the creationPolicy property
to "all", the processedDescriptors property
for its second pane is set to true during application startup.
For classes that are not containers, which do not have descriptors,
it is set to true after the createChildren()
method creates any internal component children.

A reference to the Repeater object
in the parent document that produced this UIComponent.
Use this property, rather than the repeaters property,
when the UIComponent is created by a single Repeater object.
Use the repeaters property when this UIComponent is created
by nested Repeater objects.
The property is set to null when this UIComponent
is not created by a Repeater.

The index of the item in the data provider
of the Repeater that produced this UIComponent.
Use this property, rather than the repeaterIndices property,
when the UIComponent is created by a single Repeater object.
Use the repeaterIndices property when this UIComponent is created
by nested Repeater objects.
This property is set to -1 when this UIComponent is not created by a Repeater.
Implementation
public function get repeaterIndex():intrepeaterIndices | property |
repeaterIndices:Array| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
An Array containing the indices of the items in the data provider of the Repeaters in the parent document that produced this UIComponent. The Array is empty unless this UIComponent is within one or more Repeaters.
The first element in the Array corresponds to the outermost Repeater.
For example, if repeaterIndices is [2,4] it means that the
outer repeater used item dataProvider[2] and the inner repeater
used item dataProvider[4].
Note that this property differs from the instanceIndices property
if the startingIndex property of any of the Repeaters is not 0.
For example, even if a Repeater starts at dataProvider[4],
the document reference of the first repeated object is b[0], not b[4].

For components, this layout constraint property is a
facade on top of the similarly-named style. To set
the property to its default value of undefined,
use the @Clear() directive in MXML or the undefined

By default the anchor target is the container's content area. In layouts with advanced constraints, the target can be a constraint column.
Setting the property to a number or to a numerical string like "10" specifies use of the default anchor target.

A scaleX of 2.0 means the object has been
magnified by a factor of 2, and a scaleX of 0.5
means the object has been reduced by a factor of 2.
A value of 0.0 is an invalid value.
Rather than setting it to 0.0, set it to a small value, or set

styleDeclaration:CSSStyleDeclaration| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Storage for the inline inheriting styles on this object.
This CSSStyleDeclaration is created the first time that
the setStyle() method
is called on this component to set an inheriting style.
Developers typically never need to access this property directly.
Implementation

styleName:Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The class style used by this component. This can be a String, CSSStyleDeclaration or an IStyleClient.
If this is a String, it is the name of one or more whitespace delimited class
declarations in an <fx:Style> tag or CSS file. You do not include the period
in the styleName. For example, if you have a class style named ".bigText",
set the styleName property to "bigText" (no period).
If this is an IStyleClient (typically a UIComponent), all styles in the
styleName object are used by this component.
The default value is null.

tabFocusEnabled:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
A flag that indicates whether this object can receive focus via the TAB key
This is similar to the tabEnabled property
used by the Flash Player.
This is usually true for components that
handle keyboard input, but some components in controlbars
have them set to false because they should not steal
focus from another component like an editor.
The default value is true.
This property can be used as the source for data binding. When this property is modified, it dispatches the tabFocusEnabledChange event.
Implementation
public function get tabFocusEnabled():Boolean public function set tabFocusEnabled(value:Boolean):voidtoolTip | property |
toolTip:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Text to display in the ToolTip.
The default value is null.
This property can be used as the source for data binding. When this property is modified, it dispatches the toolTipChanged event.
Implementation
public function get toolTip():String public function set toolTip(value:String):voidtop | property |
top:Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
For components, this layout constraint property is a
facade on top of the similarly-named style. To set
the property to its default value of undefined,
use the @Clear() directive in MXML or the undefined
value in ActionScript code. For example, in MXML code,
top.s2="@Clear()" unsets the top
constraint in state s2. Or in ActionScript code,
button.top = undefined unsets the top
constraint on button.
By default the anchor target is the container's content area. In layouts with advanced constraints, the target can be a constraint row.
Setting the property to a number or to a numerical string like "10" specifies use of the default anchor target.
To specify an anchor target, set the property value to a string in the format "anchorTargetName:value". For example, "row1:10".
Implementation
public function get top():Object public function set top(value:Object):voidtransform | property |
transform:flash.geom:Transform[override] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
An object with properties pertaining to a display object's matrix, color transform,
and pixel bounds. The specific properties — matrix, colorTransform, and three read-only
properties (concatenatedMatrix, concatenatedColorTransform, and pixelBounds) —
are described in the entry for the Transform class.
Each of the transform object's properties is itself an object. This concept is important because the only way to set new values for the matrix or colorTransform objects is to create a new object and copy that object into the transform.matrix or transform.colorTransform property.
For example, to increase the tx value of a display object's matrix, you must make a copy of the entire matrix object, then copy the new object into the matrix property of the transform object:
var myMatrix:Matrix = myUIComponentObject.transform.matrix;
myMatrix.tx += 10;
myUIComponent.transform.matrix = myMatrix;
You cannot directly set the tx property. The following code has no effect on myUIComponent:
myUIComponent.transform.matrix.tx += 10;
Note that for UIComponent, unlike DisplayObject, the transform
keeps the matrix and matrix3D values in sync and matrix3D is not null
even when the component itself has no 3D properties set. Developers should use the is3D property
to check if the component has 3D propertis set. If the component has 3D properties, the transform's
matrix3D should be used instead of transform's matrix.

Sets the x coordinate for the transform center of the component.
When this component is the target of a Spark transform effect,
you can override this property by setting
the AnimateTransform.autoCenterTransform property.
If autoCenterTransform is false, the transform
center is determined by the transformX,
transformY, and transformZ properties
of the effect target.
If autoCenterTransform is true,
the effect occurs around the center of the target,
(width/2, height/2).
Setting this property on the Spark effect class overrides the setting on the target component.

tweeningProperties | property |
tweeningProperties:Array| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Array of properties that are currently being tweened on this object.
Used to alert the EffectManager that certain properties of this object are being tweened, so that the EffectManger doesn't attempt to animate the same properties.
Implementation
public function get tweeningProperties():Array public function set tweeningProperties(value:Array):voiduid | property |
uid:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A unique identifier for the object. Flex data-driven controls, including all controls that are subclasses of List class, use a UID to track data provider items.
Flex can automatically create and manage UIDs.
However, there are circumstances when you must supply your own
uid property by implementing the IUID interface,
or when supplying your own uid property improves processing efficiency.
UIDs do not need to be universally unique for most uses in Flex.
One exception is for messages sent by data services.

verticalCenter:Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
For components, this layout constraint property is a
facade on top of the similarly-named style. To set
the property to its default value of undefined,
use the @Clear() directive in MXML or the undefined
value in ActionScript code. For example, in MXML code,
verticalCenter.s2="@Clear()" unsets the verticalCenter
constraint in state s2. Or in ActionScript code,
button.verticalCenter = undefined unsets the verticalCenter
constraint on button.
The default anchor target is the container itself.
In layouts with advanced constraints, the anchor target can be a constraint row. Then the content area is the space between the preceding row (or container side) and the target row.
Setting the property to a number or to a numerical string like "10" specifies use of the default anchor target.
To specify an anchor target, set the property value to a string in the format "constraintColumnId:value". For example, "row1:10".

visible:Boolean[override] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Whether or not the display object is visible.
Display objects that are not visible are disabled.
For example, if visible=false for an InteractiveObject instance,
it cannot be clicked.
When setting to true, the object dispatches
a show event.
When setting to false, the object dispatches
a hide event.
In either case the children of the object does not emit a
show or hide event unless the object
has specifically written an implementation to do so.
This property can be used as the source for data binding. When this property is modified, it dispatches the show event.

width:Number[override] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Number that specifies the width of the component, in pixels, in the parent's coordinates. The default value is 0, but this property contains the actual component width after Flex completes sizing the components in your application.
Note: You can specify a percentage value in the MXML
width attribute, such as width="100%",
but you cannot use a percentage value in the width
property in ActionScript.
Use the percentWidth property instead.
Setting this property causes a resize event to
be dispatched.
See the resize event for details on when
this event is dispatched.
This property can be used as the source for data binding. When this property is modified, it dispatches the widthChanged event.

x | property |
x:Number[override] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Number that specifies the component's horizontal position, in pixels, within its parent container.
Setting this property directly or calling move()
has no effect -- or only a temporary effect -- if the
component is parented by a layout container such as HBox, Grid,
or Form, because the layout calculations of those containers
set the x position to the results of the calculation.
However, the x property must almost always be set
when the parent is a Canvas or other absolute-positioning
container because the default value is 0.
The default value is 0.
This property can be used as the source for data binding. When this property is modified, it dispatches the xChanged event.

z:Number[override] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Indicates the z coordinate position along the z-axis of the DisplayObject instance relative to the 3D parent container. The z property is used for 3D coordinates, not screen or pixel coordinates.
When you set a z property for a display object to something other than the default
value of 0, a corresponding Matrix3D object is automatically created. for adjusting a
display object's position and orientation
in three dimensions. When working with the z-axis,
the existing behavior of x and y properties changes from screen or pixel coordinates to
positions relative to the 3D parent container.
For example, a child of the _root at position x = 100, y = 100, z = 200
is not drawn at pixel location (100,100). The child is drawn wherever the 3D projection
calculation puts it. The calculation is:
(x*cameraFocalLength/cameraRelativeZPosition, y*cameraFocalLength/cameraRelativeZPosition)
This property can be used as the source for data binding. When this property is modified, it dispatches the zChanged event.

addStyleClient | () | method |
public function addStyleClient(styleClient:IAdvancedStyleClient):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4.5 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Adds a non-visual style client to this component instance. Once
this method has been called, the style client will inherit style
changes from this component instance. Style clients that are
DisplayObjects must use the addChild or
addChildAt methods to be added to a
UIComponent.
As a side effect, this method will set the styleParent
property of the styleClient parameter to reference
this instance of the UIComponent.
If the styleClient parameter already has a
styleParent, this method will call
removeStyleClient from this previous
styleParent.
Parameters
styleClient:IAdvancedStyleClient — The IAdvancedStyleClient to
add to this component's list of non-visual style clients.
|
Throws
ArgumentError — if the styleClient parameter
is a DisplayObject.

callLater | () | method |
public function callLater(method:Function, args:Array = null):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Queues a function to be called later.
Before each update of the screen, Flash Player or AIR calls the set of functions that are scheduled for the update. Sometimes, a function should be called in the next update to allow the rest of the code scheduled for the current update to be executed. Some features, like effects, can cause queued functions to be delayed until the feature completes.
Parameters
method:Function — Reference to a method to be executed later.

| Runtime Versions: | Flash Player 9, AIR 1.1 |
Determines if the call to the measure() method can be skipped.
Boolean — Returns true when the measureSizes() method can skip the call to
the measure() method. For example this is usually true when both explicitWidth and
explicitHeight are set. For paths, this is true when the bounds of the path
have not changed.
|
childrenCreated | () | method |
protected function childrenCreated():void| Language Version: | ActionScript 3.0 |

clearStyle | () | method |
public function clearStyle(styleProp:String):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Deletes a style property from this component instance.
This does not necessarily cause the getStyle() method
to return undefined.
Parameters
styleProp:String — The name of the style property.
|
commitProperties | () | method |
protected function commitProperties():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Processes the properties set on the component. This is an advanced method that you might override when creating a subclass of UIComponent.
You do not call this method directly.
Flex calls the commitProperties() method when you
use the addChild() method to add a component to a container,
or when you call the invalidateProperties() method of the component.
Calls to the commitProperties() method occur before calls to the
measure() method. This lets you set property values that might
be used by the measure() method.
Some components have properties that affect the number or kinds
of child objects that they need to create, or have properties that
interact with each other, such as the horizontalScrollPolicy
and horizontalScrollPosition properties.
It is often best at startup time to process all of these
properties at one time to avoid duplicating work.

createChildren | () | method |
protected function createChildren():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Create child objects of the component. This is an advanced method that you might override when creating a subclass of UIComponent.
A component that creates other components or objects within it is called a composite component.
For example, the Flex ComboBox control is actually made up of a TextInput control
to define the text area of the ComboBox, and a Button control to define the ComboBox arrow.
Components implement the createChildren() method to create child
objects (such as other components) within the component.
From within an override of the createChildren() method,
you call the addChild() method to add each child object.
You do not call this method directly. Flex calls the
createChildren() method in response to the call to
the addChild() method to add the component to its parent.

createInFontContext | () | method |
protected function createInFontContext(classObj:Class):Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Creates a new object using a context based on the embedded font being used.
This method is used to solve a problem with access to fonts embedded in an application SWF when the framework is loaded as an RSL (the RSL has its own SWF context). Embedded fonts can only be accessed from the SWF file context in which they were created. By using the context of the application SWF, the RSL can create objects in the application SWF context that has access to the application's embedded fonts.
Call this method only after the font styles for this object are set.
Parameters
classObj:Class — The class to create.
|
Object — The instance of the class created in the context
of the SWF owning the embedded font.
If this object is not using an embedded font,
the class is created in the context of this object.

override public function dispatchEvent(event:Event):Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Dispatches an event into the event flow.
The event target is the EventDispatcher object upon which
the dispatchEvent() method is called.
Parameters
event:Event — The Event object that is dispatched into the event flow.
If the event is being redispatched, a clone of the event is created automatically.
After an event is dispatched, its target property cannot be changed,
so you must create a new copy of the event for redispatching to work.
|
Boolean — A value of true if the event was successfully dispatched.
A value of false indicates failure or that
the preventDefault() method was called on the event.

drawRoundRect | () | method |
public function drawRoundRect(x:Number, y:Number, w:Number, h:Number, r:Object = null, c:Object = null, alpha:Object = null, rot:Object = null, gradient:String = null, ratios:Array = null, hole:Object = null):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Programmatically draws a rectangle into this skin's Graphics object.
The rectangle can have rounded corners. Its edges are stroked with the current line style of the Graphics object. It can have a solid color fill, a gradient fill, or no fill. A solid fill can have an alpha transparency. A gradient fill can be linear or radial. You can specify up to 15 colors and alpha values at specified points along the gradient, and you can specify a rotation angle or transformation matrix for the gradient. Finally, the rectangle can have a rounded rectangular hole carved out of it.
This versatile rectangle-drawing routine is used by many skins.
It calls the drawRect() or
drawRoundRect()
methods (in the flash.display.Graphics class) to draw into this
skin's Graphics object.
Parameters
x:Number — Horizontal position of upper-left corner
of rectangle within this skin.
| |
y:Number — Vertical position of upper-left corner
of rectangle within this skin.
| |
w:Number — Width of rectangle, in pixels.
| |
h:Number — Height of rectangle, in pixels.
| |
r:Object (default = null)null, a Number, or an Object.
If it is null, it specifies that the corners should be square
rather than rounded.
If it is a Number, it specifies the same radius, in pixels,
for all four corners.
If it is an Object, it should have properties named
tl, tr, bl, and
br, whose values are Numbers specifying
the radius, in pixels, for the top left, top right,
bottom left, and bottom right corners.
For example, you can pass a plain Object such as
{ tl: 5, tr: 5, bl: 0, br: 0 }.
The default value is null (square corners).
| |
c:Object (default = null)null, a uint, or an Array.
If it is null, the rectangle not filled.
If it is a uint, it specifies an RGB fill color.
For example, pass 0xFF0000 to fill with red.
If it is an Array, it should contain uints
specifying the gradient colors.
For example, pass [ 0xFF0000, 0xFFFF00, 0x0000FF ]
to fill with a red-to-yellow-to-blue gradient.
You can specify up to 15 colors in the gradient.
The default value is null (no fill).
| |
alpha:Object (default = null)color is null.
If color is a uint specifying an RGB fill color,
then alpha should be a Number specifying
the transparency of the fill, where 0.0 is completely transparent
and 1.0 is completely opaque.
You can also pass null instead of 1.0 in this case
to specify complete opaqueness.
If color is an Array specifying gradient colors,
then alpha should be an Array of Numbers, of the
same length, that specifies the corresponding alpha values
for the gradient.
In this case, the default value is null (completely opaque).
| |
rot:Object (default = null)horizontalGradientMatrix(),
verticalGradientMatrix(), and
rotatedGradientMatrix() can be used to create the value for
this parameter.
| |
gradient:String (default = null)GradientType.LINEAR or GradientType.RADIAL.
(The GradientType class is in the package flash.display.)
| |
ratios:Array (default = null)color parameter.
Each value defines the percentage of the width where the color is
sampled at 100%. The value 0 represents the left-hand position in
the gradient box, and 255 represents the right-hand position in the
gradient box.
| |
hole:Object (default = null) |

This same method is used to get any kind of style property, so the value returned can be a Boolean, String, Number, int, uint (for an RGB color), Class (for a skin), or any kind of object. Therefore the return type is simply specified as *.
If you are getting a particular style property, you know its type and often want to store the result in a variable of that type. No casting from * to that type is necessary.
var backgroundColor:uint = getStyle("backgroundColor");
If the style property has not been set anywhere in the
style lookup chain, the value returned by getStyle()
is undefined.
Note that undefined is a special value that is
not the same as false, "",
NaN, 0, or null.
No valid style value is ever undefined.
You can use the method
IStyleManager2.isValidStyleValue()
to test whether the value was set.
Parameters
styleProp:String — Name of the style property.
|
* — Style value.

initializationComplete | () | method |
protected function initializationComplete():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Finalizes the initialization of this component.
This method is the last code that executes when you add a component
to a parent for the first time using addChild()
or addChildAt().
It handles some housekeeping related to dispatching
the initialize event.
If you are writing a component, you do not need
to override this method.
initialize | () | method |
public function initialize():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Initializes the internal structure of this component.
Initializing a UIComponent is the fourth step in the creation
of a visual component instance, and happens automatically
the first time that the instance is added to a parent.
Therefore, you do not generally need to call
initialize(); the Flex framework calls it for you
from UIComponent's override of the addChild()
and addChildAt() methods.
The first step in the creation of a visual component instance
is construction, with the new operator:
var okButton:Button = new Button();
After construction, the new Button instance is a solitary DisplayObject; it does not yet have a UITextField as a child to display its label, and it doesn't have a parent.
The second step is configuring the newly-constructed instance with the appropriate properties, styles, and event handlers:
okButton.label = "OK";
okButton.setStyle("cornerRadius", 0);
okButton.addEventListener(MouseEvent.CLICK, clickHandler);
The third step is adding the instance to a parent:
someContainer.addChild(okButton);
A side effect of calling addChild()
or addChildAt(), when adding a component to a parent
for the first time, is that initialize gets
automatically called.
This method first dispatches a preinitialize event,
giving developers using this component a chance to affect it
before its internal structure has been created.
Next it calls the createChildren() method
to create the component's internal structure; for a Button,
this method creates and adds the UITextField for the label.
Then it dispatches an initialize event,
giving developers a chance to affect the component
after its internal structure has been created.
Note that it is the act of attaching a component to a parent for the first time that triggers the creation of its internal structure. If its internal structure includes other UIComponents, then this is a recursive process in which the tree of DisplayObjects grows by one leaf node at a time.
If you are writing a component, you do not need to override this method.

| Runtime Versions: | Flash Player 9, AIR 1.1 |
Initializes this component's accessibility code.
This method is called by the initialize() method to hook in the
component's accessibility code, which resides in a separate class
in the mx.accessibility package.
Each subclass that supports accessibility must override this method
because the hook-in process uses a different static variable
in each subclass.
initializeRepeaterArrays | () | method |
public function initializeRepeaterArrays(parent:IRepeaterClient):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Initializes various properties which keep track of repeated instances of this component.
An MXML <mx:Repeater/> tag can cause repeated instances
of a component to be created, one instance for each item in the
Repeater's data provider.
The instanceIndices, repeaters,
and repeaterIndices properties of UIComponent
keep track of which instance came from which data item
and which Repeater.
This method is an internal method which is automatically called by the Flex framework. You do not have to call it or override it.
Parameters
parent:IRepeaterClient — The parent object containing the Repeater that created
this component.

invalidateDisplayList | () | method |
public function invalidateDisplayList():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Marks a component so that its updateDisplayList()
method gets called during a later screen update.
Invalidation is a useful mechanism for eliminating duplicate work by delaying processing of changes to a component until a later screen update. For example, if you want to change the width and height, it would be wasteful to update the component immediately after you change the width and then update again with the new height. It is more efficient to change both properties and then render the component with its new size once.
Invalidation methods rarely get called. In general, setting a property on a component automatically calls the appropriate invalidation method.
invalidateLayering | () | method |
public function invalidateLayering():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.4 |
Called by a component's items to indicate that their depth
property has changed. Note that while this function is defined on
UIComponent, it is up to subclasses to implement support
for complex layering.
By default, only Group and DataGroup support
arbitrary layering of their children.

invalidateLayoutDirection | () | method |
public function invalidateLayoutDirection():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
An element must call this method when its layoutDirection changes or when its parent's layoutDirection changes. If they differ, this method is responsible for mirroring the element’s contents and for updating the element’s post-layout transform so that descendants inherit a mirrored coordinate system. IVisualElements typically implement mirroring by using postLayoutTransformOffsets to scale the X axis by -1 and to translate the x coordinate of the origin by the element's width. The net effect of this "mirror" transform is to reverse the direction in which the X axis increases without changing the element's location relative to its parent's origin.
invalidateParentSizeAndDisplayList | () | method |
protected function invalidateParentSizeAndDisplayList():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Helper method to invalidate parent size and display list if this object affects its layout (includeInLayout is true).
invalidateProperties | () | method |
public function invalidateProperties():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Marks a component so that its commitProperties()
method gets called during a later screen update.
Invalidation is a useful mechanism for eliminating duplicate work by delaying processing of changes to a component until a later screen update. For example, if you want to change the text color and size, it would be wasteful to update the color immediately after you change it and then update the size when it gets set. It is more efficient to change both properties and then render the text with its new size and color once.
Invalidation methods rarely get called. In general, setting a property on a component automatically calls the appropriate invalidation method.
invalidateSize | () | method |
public function invalidateSize():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Marks a component so that its measure()
method gets called during a later screen update.
Invalidation is a useful mechanism for eliminating duplicate work by delaying processing of changes to a component until a later screen update. For example, if you want to change the text and font size, it would be wasteful to update the text immediately after you change it and then update the size when it gets set. It is more efficient to change both properties and then render the text with its new size once.
Invalidation methods rarely get called. In general, setting a property on a component automatically calls the appropriate invalidation method.

Returns true if cssState matches currentCSSState.
Typically, you do not call this method directly.
It is called by the mx.styles.CSSCondition.matchesStyleClient() method.
Note Spark components use their skin state as the pseudo state.
Halo components use the currentState property.

measure | () | method |
protected function measure():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Calculates the default size, and optionally the default minimum size, of the component. This is an advanced method that you might override when creating a subclass of UIComponent.
You do not call this method directly. Flex calls the
measure() method when the component is added to a container
using the addChild() method, and when the component's
invalidateSize() method is called.
When you set a specific height and width of a component,
Flex does not call the measure() method,
even if you explicitly call the invalidateSize() method.
That is, Flex only calls the measure() method if
the explicitWidth property or the explicitHeight
property of the component is NaN.
In your override of this method, you must set the
measuredWidth and measuredHeight properties
to define the default size.
You can optionally set the measuredMinWidth and
measuredMinHeight properties to define the default
minimum size.
Most components calculate these values based on the content they are displaying, and from the properties that affect content display. A few components simply have hard-coded default values.
The conceptual point of measure() is for the component to provide
its own natural or intrinsic size as a default. Therefore, the
measuredWidth and measuredHeight properties
should be determined by factors such as:
- The amount of text the component needs to display.
- The styles, such as
fontSize, for that text. - The size of a JPEG image that the component displays.
- The measured or explicit sizes of the component's children.
- Any borders, margins, and gaps.
In some cases, there is no intrinsic way to determine default values.
For example, a simple GreenCircle component might simply set
measuredWidth = 100 and measuredHeight = 100 in its measure() method to
provide a reasonable default size. In other cases, such as a TextArea,
an appropriate computation (such as finding the right width and height
that would just display all the text and have the aspect ratio of a Golden Rectangle)
might be too time-consuming to be worthwhile.
The default implementation of measure()
sets measuredWidth, measuredHeight,
measuredMinWidth, and measuredMinHeight
to 0.

measureHTMLText | () | method |
public function measureHTMLText(htmlText:String):flash.text:TextLineMetrics| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Measures the specified HTML text, which can contain HTML tags such
as <font> and <b>,
assuming that it is displayed
in a single-line UITextField using a UITextFormat
determined by the styles of this UIComponent.
Parameters
htmlText:String — A String specifying the HTML text to measure.
|
flash.text:TextLineMetrics — A TextLineMetrics object containing the text measurements.
|
measureText | () | method |
public function measureText(text:String):flash.text:TextLineMetrics| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Measures the specified text, assuming that it is displayed in a single-line UITextField (or UIFTETextField) using a UITextFormat determined by the styles of this UIComponent. Does not work for Spark components since they don't use UITextField (or UIFTETextField). To measure text in Spark components, get the measurements of a spark.components.Label or spark.components.RichText
Parameters
text:String — A String specifying the text to measure.
|
flash.text:TextLineMetrics — A TextLineMetrics object containing the text measurements.

move | () | method |
public function move(x:Number, y:Number):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Moves the component to a specified position within its parent.
Calling this method is exactly the same as
setting the component's x and y properties.
If you are overriding the updateDisplayList() method
in a custom component, call the move() method
rather than setting the x and y properties.
The difference is that the move() method changes the location
of the component and then dispatches a move event when you
call the method, while setting the x and y
properties changes the location of the component and dispatches
the event on the next screen refresh.
Parameters
x:Number — Left position of the component within its parent.
| |
y:Number — Top position of the component within its parent.

regenerateStyleCache | () | method |
public function regenerateStyleCache(recursive:Boolean):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Builds or rebuilds the CSS style cache for this component
and, if the recursive parameter is true,
for all descendants of this component as well.
The Flex framework calls this method in the following situations:
- When you add a UIComponent to a parent using the
addChild()oraddChildAt()methods. - When you change the
styleNameproperty of a UIComponent. - When you set a style in a CSS selector using the
setStyle()method of CSSStyleDeclaration.
Building the style cache is a computation-intensive operation,
so avoid changing styleName or
setting selector styles unnecessarily.
This method is not called when you set an instance style
by calling the setStyle() method of UIComponent.
Setting an instance style is a relatively fast operation
compared with setting a selector style.
You do not need to call or override this method.
Parameters
recursive:Boolean — Recursively regenerates the style cache for
all children of this component.

Once this method has been called, the non-visual style client will
no longer inherit style changes from this component instance.
As a side effect, this method will set the
styleParent property of the styleClient
parameter to null.
If the styleClient has not been added to this
component instance, no action will be taken.
Parameters
styleClient:IAdvancedStyleClient — The IAdvancedStyleClient to remove
from this component's list of non-visual style clients.

This method is called when a UIComponent is constructed,
and again whenever the ResourceManager dispatches
a "change" Event to indicate
that the localized resources have changed in some way.
This event is dispatched when you set the ResourceManager's
localeChain property, when a resource module
has finished loading, and when you call the ResourceManager's
update() method.
Subclasses should override this method and, after calling
super.resourcesChanged(), do whatever is appropriate
in response to having new resource values.
resumeBackgroundProcessing | () | method |
public static function resumeBackgroundProcessing():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |

setActualSize | () | method |
public function setActualSize(w:Number, h:Number):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Sizes the object.
Unlike directly setting the width and height
properties, calling the setActualSize() method
does not set the explictWidth and
explicitHeight properties, so a future layout
calculation can result in the object returning to its previous size.
This method is used primarily by component developers implementing
the updateDisplayList() method, by Effects,
and by the LayoutManager.
Parameters
w:Number — Width of the object.
| |
h:Number — Height of the object.
|
setConstraintValue | () | method |
public function setConstraintValue(constraintName:String, value:*):void| Language Version: | ActionScript 3.0 |

Sets a layout constraint value, which is the same as setting the constraint style for this component.
Parameters
constraintName:String — The name of the constraint style, which
can be any of the following: left, right, top, bottom,
verticalCenter, horizontalCenter, baseline
| |
value:* — The value of the constraint can be specified in either
of two forms. It can be specified as a numeric string, for
example, "10" or it can be specified as identifier:numeric
string. For identifier:numeric string, identifier is the
id of a ConstraintRow or ConstraintColumn. For
example, a value of "cc1:10" specifies a value of 10 for the
ConstraintColumn that has the id "cc1."

setLayoutBoundsPosition | () | method |
public function setLayoutBoundsPosition(x:Number, y:Number, postLayoutTransform:Boolean = true):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Sets the coordinates that the element uses to draw on screen.
Note that calls to the setLayoutBoundSize() method can affect the layout position, so
call setLayoutBoundPosition() after calling setLayoutBoundSize().
Parameters
x:Number — The x-coordinate of the top-left corner of the bounding box.
| |
y:Number — The y-coordinate of the top-left corner of the bounding box.
| |
postLayoutTransform:Boolean (default = true)postLayoutTransform is true,
the element is positioned in such a way that the top-left corner of its bounding box is (x, y).
The bounding box is in the element's parent coordinate space and is calculated
from the element's layout size, layout position and layout transform matrix.
|
setLayoutBoundsSize | () | method |
public function setLayoutBoundsSize(width:Number, height:Number, postLayoutTransform:Boolean = true):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Sets the layout size of the element. This is the size that the element uses to draw on screen.
If the width and/or height parameters are left unspecified (NaN),
Flex sets the element's layout size to its preferred width and/or preferred height.
Note that calls to the setLayoutBoundSize() method can affect the layout position, so
call setLayoutBoundPosition() after calling setLayoutBoundSize().
Parameters
width:Number — The element's layout width.
| |
height:Number — The element's layout height.
| |
postLayoutTransform:Boolean (default = true)postLayoutTransform is true, the specified sizes
are those of the element's bounding box.

setLayoutMatrix | () | method |
public function setLayoutMatrix(value:Matrix, invalidateLayout:Boolean):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Sets the transform Matrix that is used to calculate the component's layout size and position relative to its siblings.
The matrix is typically defined by the
component's 2D properties such as x, y,
rotation, scaleX, scaleY,
transformX, and transformY.
Some components may have additional transform properties that
are applied on top of the layout matrix to determine the final,
computed matrix. For example UIComponent
defines the offsets.
Note that layout Matrix is factored in the getPreferredSize(),
getMinSize(), getMaxSize(), getLayoutSize()
methods when computed in parent coordinates
as well as in getLayoutPosition() in both parent and child coordinates.
Layouts that calculate the transform matrix explicitly typically call
this method and work with sizes in child coordinates.
Layouts calling this method pass false
to the invalidateLayout() method so that a subsequent layout pass is not
triggered.
Parameters
value:Matrix — The matrix.
| |
invalidateLayout:Boolean — true to cause the parent container
to re-layout its children. You typically pass true
to the invalidateLayout() method.
|
setLayoutMatrix3D | () | method |
public function setLayoutMatrix3D(value:Matrix3D, invalidateLayout:Boolean):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Sets the transform Matrix3D that is used to calculate the component's layout size and position relative to its siblings.
This matrix is typically defined by the
component's transform properties such as x, y,
z, rotationX, rotationY,
rotationZ, scaleX, scaleY,
scaleZ, transformX, and transformY.
Some components may have additional transform properties that
are applied on top of the layout matrix to determine the final,
computed matrix. For example UIComponent
defines the offsets property.
Note that layout Matrix3D is factored in the getPreferredSize(),
getMinSize(), getMaxSize(), getLayoutSize()
when computed in parent coordinates
as well as in getLayoutPosition() in both parent and child coordinates.
Layouts that calculate the transform matrix explicitly typically call
this method and work with sizes in child coordinates.
Layouts calling this method pass false
to the invalidateLayout() method so that a subsequent layout pass is not
triggered.
Parameters
value:Matrix3D — The matrix.
| |
invalidateLayout:Boolean — true to cause the parent container
to re-layout its children. You typically pass true
to the invalidateLayout() method.

protected function stateChanged(oldState:String, newState:String, recursive:Boolean):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
This method is called when a state changes to check whether
state-specific styles apply to this component. If there is a chance
of a matching CSS pseudo-selector for the current state, the style
cache needs to be regenerated for this instance and, potentially all
children, if the recursive param is set to true.
Parameters
oldState:String — The name of th eold state.
| |
newState:String — The name of the new state.
| |
recursive:Boolean — Set to true to perform a recursive check.
|
styleChanged | () | method |
public function styleChanged(styleProp:String):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Detects changes to style properties. When any style property is set,
Flex calls the styleChanged() method,
passing to it the name of the style being set.
This is an advanced method that you might override
when creating a subclass of UIComponent. When you create a custom component,
you can override the styleChanged() method
to check the style name passed to it, and handle the change accordingly.
This lets you override the default behavior of an existing style,
or add your own custom style properties.
If you handle the style property, your override of
the styleChanged() method should call the
invalidateDisplayList() method to cause Flex to execute
the component's updateDisplayList() method at the next screen update.
Parameters
styleProp:String — The name of the style property, or null if all styles for this
component have changed.
|
stylesInitialized | () | method |
public function stylesInitialized():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Flex calls the stylesInitialized() method when
the styles for a component are first initialized.
This is an advanced method that you might override
when creating a subclass of UIComponent. Flex guarantees that
your component's styles are fully initialized before
the first time your component's measure and
updateDisplayList methods are called. For most
components, that is sufficient. But if you need early access to
your style values, you can override the stylesInitialized() function
to access style properties as soon as they are initialized the first time.
suspendBackgroundProcessing | () | method |
public static function suspendBackgroundProcessing():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Blocks the background processing of methods
queued by callLater(),
until resumeBackgroundProcessing() is called.
These methods can be useful when you have time-critical code
which needs to execute without interruption.
For example, when you set the suspendBackgroundProcessing
property of an Effect to true,
suspendBackgroundProcessing() is automatically called
when it starts playing, and resumeBackgroundProcessing
is called when it stops, in order to ensure that the animation
is smooth.
Since the LayoutManager uses callLater(),
this means that commitProperties(),
measure(), and updateDisplayList()
is not called in between calls to
suspendBackgroundProcessing() and
resumeBackgroundProcessing().
It is safe for both an outer method and an inner method
(i.e., one that the outer methods calls) to call
suspendBackgroundProcessing()
and resumeBackgroundProcessing(), because these
methods actually increment and decrement a counter
which determines whether background processing occurs.
transformAround | () | method |
public function transformAround(transformCenter:Vector3D, scale:Vector3D = null, rotation:Vector3D = null, translation:Vector3D = null, postLayoutScale:Vector3D = null, postLayoutRotation:Vector3D = null, postLayoutTranslation:Vector3D = null, invalidateLayout:Boolean = true):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
A utility method to update the rotation, scale, and translation of the transform while keeping a particular point, specified in the component's own coordinate space, fixed in the parent's coordinate space. This function will assign the rotation, scale, and translation values provided, then update the x/y/z properties as necessary to keep the transform center fixed.
Parameters
transformCenter:Vector3D — The point, in the component's own coordinates,
to keep fixed relative to its parent.
| |
scale:Vector3D (default = null) | |
rotation:Vector3D (default = null) | |
translation:Vector3D (default = null) | |
postLayoutScale:Vector3D (default = null) | |
postLayoutRotation:Vector3D (default = null) | |
postLayoutTranslation:Vector3D (default = null) | |
invalidateLayout:Boolean (default = true)true, the parent container size and display are
invalidated. Layouts calling this method pass false
so that a subsequent layout pass is not triggered.
|
transformPointToParent | () | method |
public function transformPointToParent(localPosition:Vector3D, position:Vector3D, postLayoutPosition:Vector3D):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
A utility method to transform a point specified in the local
coordinates of this object to its location in the object's parent's
coordinates. The pre-layout and post-layout result is set on
the position and postLayoutPosition
parameters, if they are non-null.
Parameters
localPosition:Vector3D — The point to be transformed, specified in the
local coordinates of the object.
| |
position:Vector3D — A Vector3D point that holds the pre-layout
result. If null, the parameter is ignored.
| |
postLayoutPosition:Vector3D — A Vector3D point that holds the post-layout
result. If null, the parameter is ignored.

updateDisplayList | () | method |
protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Draws the object and/or sizes and positions its children. This is an advanced method that you might override when creating a subclass of UIComponent.
You do not call this method directly. Flex calls the
updateDisplayList() method when the component is added to a container
using the addChild() method, and when the component's
invalidateDisplayList() method is called.
If the component has no children, this method
is where you would do programmatic drawing
using methods on the component's Graphics object
such as graphics.drawRect().
If the component has children, this method is where
you would call the move() and setActualSize()
methods on its children.
Components can do programmatic drawing even if
they have children. In doing either, use the
component's unscaledWidth and unscaledHeight
as its bounds.
It is important to use unscaledWidth and
unscaledHeight instead of the width
and height properties.
Parameters
unscaledWidth:Number — Specifies the width of the component, in pixels,
in the component's coordinates, regardless of the value of the
scaleX property of the component.
| |
unscaledHeight:Number — Specifies the height of the component, in pixels,
in the component's coordinates, regardless of the value of the
scaleY property of the component.

validateDisplayList | () | method |
public function validateDisplayList():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Validates the position and size of children and draws other
visuals.
If the LayoutManager.invalidateDisplayList() method is called with
this ILayoutManagerClient, then the validateDisplayList() method
is called when it's time to update the display list.
validateNow | () | method |
public function validateNow():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Validate and update the properties and layout of this object
and redraw it, if necessary.
Processing properties that require substantial computation are normally
not processed until the script finishes executing.
For example setting the width property is delayed, because it can
require recalculating the widths of the objects children or its parent.
Delaying the processing prevents it from being repeated
multiple times if the script sets the width property more than once.
This method lets you manually override this behavior.
validateProperties | () | method |
public function validateProperties():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Used by layout logic to validate the properties of a component
by calling the commitProperties() method.
In general, subclassers should
override the commitProperties() method and not this method.
validateSize | () | method |
public function validateSize(recursive:Boolean = false):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Validates the measured size of the component
If the LayoutManager.invalidateSize() method is called with
this ILayoutManagerClient, then the validateSize() method
is called when it's time to do measurements.
Parameters
recursive:Boolean (default = false)true, call this method
on the objects children.
|
validationResultHandler | () | method |
public function validationResultHandler(event:ValidationResultEvent):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Handles both the valid and invalid events from a
validator assigned to this component.
You typically handle the valid and invalid events
dispatched by a validator by assigning event listeners to the validators.
If you want to handle validation events directly in the component that is being validated,
you can override this method to handle the valid
and invalid events. You typically call
super.validationResultHandler(event) in your override.
Parameters
event:ValidationResultEvent — The event object for the validation.

| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Dispatched by the drag initiator (the component that is the source of the data being dragged) when the drag operation completes, either when you drop the dragged data onto a drop target or when you end the drag-and-drop operation without performing a drop.
You can use this event to perform any final cleanup of the drag-and-drop operation. For example, if you drag a List control item from one list to another, you can delete the List control item from the source if you no longer need it.
If you call Event.preventDefault() in the event handler
for the dragComplete event for
a Tree control when dragging data from one Tree control to another,
it prevents the drop.
DragEvent.DRAG_COMPLETE constant defines the value of the
type property of the event object for a dragComplete event.
The properties of the event object have the following values:
| Property | Value |
|---|---|
action | The action that caused the event:
DragManager.COPY, DragManager.LINK,
DragManager.MOVE, or DragManager.NONE. |
bubbles | false |

Dispatched by the drop target when the user releases the mouse over it.
You use this event handler to add the drag data to the drop target.
If you call Event.preventDefault() in the event handler
for the dragDrop event for
a Tree control when dragging data from one Tree control to another,
it prevents the drop.
DragEvent.DRAG_DROP constant defines the value of the
type property of the event object for a dragDrop event.
The properties of the event object have the following values:

dragEnter | Event |
mx.events.DragEventproperty DragEvent.type =
mx.events.DragEvent.DRAG_ENTER| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Dispatched by a component when the user moves the mouse over the component during a drag operation. In an application running in Flash Player, the event is dispatched many times when you move the mouse over any component. In an application running in AIR, the event is dispatched only once.
In order to be a valid drop target, you must define a handler for this event. In the handler, you can change the appearance of the drop target to provide visual feedback to the user that the component can accept the drag. For example, you could draw a border around the drop target, or give focus to the drop target.
If you want to accept the drag, you must call the
DragManager.acceptDragDrop() method. If you don't
call acceptDragDrop(), you do not get any of the
other drag events.
In Flash Player, the value of the action property is always
DragManager.MOVE, even if you are doing a copy.
This is because the dragEnter event occurs before
the control recognizes that the Control key is pressed to signal a copy.
The action property of the event object for the
dragOver event does contain a value that signifies the type of
drag operation. You can change the type of drag action by calling the
DragManager.showFeedback() method.
In AIR, the default value of the action property is
DragManager.COPY.
Because of the way data to a Tree control is structured,
the Tree control handles drag and drop differently from the other list-based controls.
For the Tree control, the event handler for the dragDrop event
only performs an action when you move or copy data in the same Tree control,
or copy data to another Tree control.
If you drag data from one Tree control and drop it onto another Tree control
to move the data, the event handler for the dragComplete event
actually performs the work to add the data to the destination Tree control,
rather than the event handler for the dragDrop event,
and also removes the data from the source Tree control.
This is necessary because to reparent the data being moved,
Flex must remove it first from the source Tree control.
DragEvent.DRAG_ENTER constant defines the value of the
type property of the event object for a dragEnter event.
The properties of the event object have the following values:
| Property | Value |
|---|---|
action | The action that caused the event, which is always
DragManager.MOVE. |
bubbles | false |
cancelable | false |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
dragInitiator | The component that initiated the drag. |
dragSource | The DragSource object containing the data being dragged. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |

| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Dispatched by a component when the user moves the mouse while over the component during a drag operation. In Flash Player, the event is dispatched when you drag an item over a valid drop target. In AIR, the event is dispatched when you drag an item over any component, even if the component is not a valid drop target.
In the handler, you can change the appearance of the drop target to provide visual feedback to the user that the component can accept the drag. For example, you could draw a border around the drop target, or give focus to the drop target.
Handle this event to perform additional logic before allowing the drop, such as dropping data to various locations in the drop target, reading keyboard input to determine if the drag-and-drop action is a move or copy of the drag data, or providing different types of visual feedback based on the type of drag-and-drop action.
You can also change the type of drag action by changing the
DragManager.showFeedback() method.
The default value of the action property is
DragManager.MOVE.

myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |

Dispatched when values are changed programmatically or by user interaction.
Because a programmatic change triggers this event, make sure
that any valueCommit event handler does not change
a value that causes another valueCommit event.
For example, do not change a control's dataProvider
property in a valueCommit event handler.
FlexEvent.VALUE_COMMIT constant defines the value of the
type property of the event object for a valueCommit
event.
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
