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.

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

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.

hasFocusableChildren:Boolean| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 4 |
| Körningsmiljöversioner: | 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.

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%",

| Körningsmiljöversioner: | 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".

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.

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".

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

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,
right.s2="@Clear()" unsets the right
constraint in state s2. Or in ActionScript code,
button.right = undefined unsets the right
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".

transform:flash.geom:Transform[åsidosätt] | Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.

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

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:

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.
Parametrar
method:Function — Reference to a method to be executed later.

args:Array (default = null) |
canSkipMeasurement | () | metod |
protected function canSkipMeasurement():Boolean| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 4 |
| Körningsmiljöversioner: | 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 | () | metod |
protected function childrenCreated():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Performs any final processing after child objects are created. This is an advanced method that you might override when creating a subclass of UIComponent.
clearStyle | () | metod |
public function clearStyle(styleProp:String):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
Parametrar
styleProp:String — The name of the style property.
|
commitProperties | () | metod |
protected function commitProperties():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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 | () | metod |
protected function createChildren():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.

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.
Parametrar

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).

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,

public function getRepeaterItem(whichRepeater:int = -1):Object| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Returns the item in the dataProvider that was used
by the specified Repeater to produce this Repeater, or
null if this Repeater isn't repeated.
The argument whichRepeater is 0 for the outermost
Repeater, 1 for the next inner Repeater, and so on.
If whichRepeater is not specified,
the innermost Repeater is used.

getStyle | () | metod |
public function getStyle(styleProp:String):*| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Gets a style property that has been set anywhere in this component's style lookup chain.
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.
Parametrar
styleProp:String — Name of the style property.
|
* — Style value.

globalToContent | () | metod |
public function globalToContent(point:Point):Point| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Converts a Point object from global to content coordinates.
Global coordinates specify a pixel position relative to the upper-left corner
of the stage, that is, the outermost edge of the application.
Content coordinates specify a pixel position relative to the upper left corner
of the component's content, and include all of the component's content area,
including any regions that are currently clipped and must be
accessed by scrolling the component.
You use the content coordinate system to set and get the positions of children
of a container that uses absolute positioning.
Parametrar
point:Point — A Point object that
specifies the x and y coordinates in the global (Stage)
coordinate system as properties.
|
Point — Point A Point object with coordinates relative to the component.

Returns true if currentCSSState is not null.
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.
Boolean — true if currentCSSState is not null.

| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Returns a box Matrix which can be passed to the
drawRoundRect() method
as the rot parameter when drawing a horizontal gradient.
For performance reasons, the Matrix is stored in a static variable
which is reused by all calls to horizontalGradientMatrix()
and verticalGradientMatrix().
Therefore, pass the resulting Matrix
to drawRoundRect() before calling
horizontalGradientMatrix()
or verticalGradientMatrix() again.
Parametrar

Initializes the implementation and storage of some of the less frequently used advanced layout features of a component. Call this function before attempting to use any of the features implemented by the AdvancedLayoutFeatures object.
initializationComplete | () | metod |
protected function initializationComplete():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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 | () | metod |
public function initialize():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
initializeAccessibility | () | metod |
protected function initializeAccessibility():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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 | () | metod |
public function initializeRepeaterArrays(parent:IRepeaterClient):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
Parametrar
parent:IRepeaterClient — The parent object containing the Repeater that created
this component.

invalidateDisplayList | () | metod |
public function invalidateDisplayList():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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 | () | metod |
public function invalidateLayering():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 4 |
| Körningsmiljöversioner: | 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 | () | metod |
public function invalidateLayoutDirection():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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 | () | metod |
protected function invalidateParentSizeAndDisplayList():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |

invalidateProperties | () | metod |
public function invalidateProperties():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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 | () | metod |
public function invalidateSize():void| Språkversion: | ActionScript 3.0 |

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.

public function localToContent(point:Point):Point| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Converts a Point object from local to content coordinates.
Local coordinates specify a pixel position relative to the
upper left corner of the component.
Content coordinates specify a pixel position relative to the upper left corner
of the component's content, and include all of the component's content area,
including any regions that are currently clipped and must be
accessed by scrolling the component.
You use the content coordinate system to set and get the positions of children
of a container that uses absolute positioning.

|
measure | () | metod |
protected function measure():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.

move | () | metod |
public function move(x:Number, y:Number):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
Parametrar
x:Number — Left position of the component within its parent.

regenerateStyleCache | () | metod |
public function regenerateStyleCache(recursive:Boolean):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.

update() method.
Subclasses should override this method and, after calling
super.resourcesChanged(), do whatever is appropriate
in response to having new resource values.
resumeBackgroundProcessing | () | metod |
public static function resumeBackgroundProcessing():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Resumes the background processing of methods
queued by callLater(), after a call to
suspendBackgroundProcessing().
Refer to the description of
suspendBackgroundProcessing() for more information.
setActualSize | () | metod |
public function setActualSize(w:Number, h:Number):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
Parametrar
w:Number — Width of the object.
| |
h:Number — Height of the object.
|
setConstraintValue | () | metod |
public function setConstraintValue(constraintName:String, value:*):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Sets a layout constraint value, which is the same as setting the constraint style for this component.
Parametrar
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."

setCurrentState | () | metod |
public function setCurrentState(stateName:String, playTransition:Boolean = true):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Set the current state.
Parametrar
stateName:String — The name of the new view state.
| |
playTransition:Boolean (default = true)true, play
the appropriate transition when the view state changes.
|
Relaterade API-element
setFocus | () | metod |
public function setFocus():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Sets the focus to this component. The component can in turn pass focus to a subcomponent.
Note: Only the TextInput and TextArea controls show a highlight when this method sets the focus. All controls show a highlight when the user tabs to the control.
setLayoutBoundsPosition | () | metod |
public function setLayoutBoundsPosition(x:Number, y:Number, postLayoutTransform:Boolean = true):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 4 |
| Körningsmiljöversioner: | 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().
Parametrar
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 | () | metod |
public function setLayoutBoundsSize(width:Number, height:Number, postLayoutTransform:Boolean = true):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 4 |
| Körningsmiljöversioner: | 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().
Parametrar
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.
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.
|
setLayoutMatrix | () | metod |
public function setLayoutMatrix(value:Matrix, invalidateLayout:Boolean):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 4 |
| Körningsmiljöversioner: | 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.
Parametrar
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 | () | metod |
public function setLayoutMatrix3D(value:Matrix3D, invalidateLayout:Boolean):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 4 |
| Körningsmiljöversioner: | 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.
Parametrar
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.
|
setStretchXY | () | metod |
protected function setStretchXY(stretchX:Number, stretchY:Number):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 4 |
| Körningsmiljöversioner: | Flash Player 10, AIR 1.5 |
Specifies a transform stretch factor in the horizontal and vertical direction. The stretch factor is applied to the computed matrix before any other transformation.
Parametrar
stretchX:Number — The horizontal component of the stretch factor.
| |
stretchY:Number — The vertical component of the stretch factor.
|
setStyle | () | metod |
public function setStyle(styleProp:String, newValue:*):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Sets a style property on this component instance.
This can override a style that was set globally.
Calling the setStyle() method can result in decreased performance.
Use it only when necessary.
Parametrar
styleProp:String — Name of the style property.
| |
newValue:* — New value for the style.
|
Fler exempel
setVisible | () | metod |
public function setVisible(value:Boolean, noEvent:Boolean = false):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Called when the visible property changes.
Set the visible property to show or hide
a component instead of calling this method directly.
Parametrar
value:Boolean — The new value of the visible property.
Specify true to show the component, and false to hide it.
| |
noEvent:Boolean (default = false)true, do not dispatch an event.
If false, dispatch a show event when
the component becomes visible, and a hide event when
the component becomes invisible.
|
stateChanged | () | metod |
protected function stateChanged(oldState:String, newState:String, recursive:Boolean):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 4 |
| Körningsmiljöversioner: | 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.
Parametrar
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 | () | metod |
public function styleChanged(styleProp:String):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
Parametrar
styleProp:String — The name of the style property, or null if all styles for this
component have changed.
|
stylesInitialized | () | metod |
public function stylesInitialized():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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 | () | metod |
public static function suspendBackgroundProcessing():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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 | () | metod |
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| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 4 |
| Körningsmiljöversioner: | 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.
Parametrar
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 | () | metod |
public function transformPointToParent(localPosition:Vector3D, position:Vector3D, postLayoutPosition:Vector3D):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 4 |
| Körningsmiljöversioner: | 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.
Parametrar
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 | () | metod |
protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
Parametrar
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 | () | metod |
public function validateDisplayList():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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 | () | metod |
public function validateNow():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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 | () | metod |
public function validateProperties():void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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 | () | metod |
public function validateSize(recursive:Boolean = false):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
Parametrar
recursive:Boolean (default = false)true, call this method
on the objects children.
|
validationResultHandler | () | metod |
public function validationResultHandler(event:ValidationResultEvent):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
Parametrar
event:ValidationResultEvent — The event object for the validation.

verticalGradientMatrix | () | metod |
public function verticalGradientMatrix(x:Number, y:Number, width:Number, height:Number):Matrix| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Returns a box Matrix which can be passed to drawRoundRect()
as the rot parameter when drawing a vertical gradient.
For performance reasons, the Matrix is stored in a static variable
which is reused by all calls to horizontalGradientMatrix()
and verticalGradientMatrix().
Therefore, pass the resulting Matrix
to drawRoundRect() before calling
horizontalGradientMatrix()
or verticalGradientMatrix() again.
Parametrar
x:Number — The left coordinate of the gradient, in pixels.
| |
y:Number — The top coordinate of the gradient, in pixels.
| |
width:Number — The width of the gradient, in pixels.
| |
height:Number — The height of the gradient, in pixels.

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:

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,

mx.events.DragEvent.DRAG_ENTER| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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. |

| Körningsmiljöversioner: | 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
