alpha | property |
alpha:Number
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Indicates the alpha transparency value of the object specified.
Valid values are 0 (fully transparent) to 1 (fully opaque).
The default value is 1. Display objects with alpha
set to 0 are active, even though they are invisible.
Implementation
public function get alpha():Number
public function set alpha(value:Number):void
depth | property |
depth:Number
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Determines the order in which items inside of containers
are rendered.
Spark containers order their items based on their
depth
property, with the lowest depth in the back,
and the higher in the front.
Items with the same depth value appear in the order
they are added to the container.
The default value is 0.
Implementation
public function get depth():Number
public function set depth(value:Number):void
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
.
The default value is null.
Implementation
public function get designLayer():DesignLayer
public function set designLayer(value:DesignLayer):void

height | property |
height:Number
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Indicates the height of the display object, in pixels. The height is calculated based on the bounds of the content of the display object.
When you set the height
property, the scaleY
property is adjusted accordingly, as shown in the
following code:
var rect:Shape = new Shape(); rect.graphics.beginFill(0xFF0000); rect.graphics.drawRect(0, 0, 100, 100); trace(rect.scaleY) // 1; rect.height = 200; trace(rect.scaleY) // 2;
Except for TextField and Video objects, a display object with no content (such as an empty sprite) has a height
of 0, even if you try to set height
to a different value.
Implementation
public function get height():Number
public function set height(value:Number):void
is3D | property |
is3D:Boolean
[read-only] Language Version: | ActionScript 3.0 |
Product Version: | Flex 4 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Contains true
when the element is in 3D.
The element can be in 3D either because
it has 3D transform properties or it has 3D post layout transform offsets or both.
Implementation
public function get is3D():Boolean

owner | property |
owner:DisplayObjectContainer
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
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.
Implementation
public function get owner():DisplayObjectContainer
public function set owner(value:DisplayObjectContainer):void
parent | property |
parent:DisplayObjectContainer
[read-only] Language Version: | ActionScript 3.0 |
Product Version: | Flex 4 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
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.
Implementation
public function get parent():DisplayObjectContainer
postLayoutTransformOffsets | property |
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
public function get postLayoutTransformOffsets():mx.geom:TransformOffsets
public function set postLayoutTransformOffsets(value:mx.geom:TransformOffsets):void
visible | property |
visible:Boolean
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Controls the visibility of this visual element.
If true
, the object is visible.
If an object is not visible, but the includeInLayout
property is set to true
, then the object
takes up space in the container, but is invisible.
If visible
is set to true
, the object may not
necessarily be visible due to its size and whether container clipping
is enabled.
Setting visible
to false
,
prevents the component from getting focus.
The default value is true.
Implementation
public function get visible():Boolean
public function set visible(value:Boolean):void

width | property |
width:Number
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Indicates the width of the display object, in pixels. The width is calculated based on the bounds of the content of the display object.
When you set the width
property, the scaleX
property is adjusted accordingly, as shown in the
following code:
var rect:Shape = new Shape(); rect.graphics.beginFill(0xFF0000); rect.graphics.drawRect(0, 0, 100, 100); trace(rect.scaleX) // 1; rect.width = 200; trace(rect.scaleX) // 2;
Except for TextField and Video objects, a display object with no content (such as an empty sprite) has a width
of 0, even if you try to set width
to a different value.
Implementation
public function get width():Number
public function set width(value:Number):void
x | property |
x:Number
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Indicates the x coordinate of the DisplayObject instance relative to the local coordinates of the parent DisplayObjectContainer. If the object is inside a DisplayObjectContainer that has transformations, it is in the local coordinate system of the enclosing DisplayObjectContainer. Thus, for a DisplayObjectContainer rotated 90° counterclockwise, the DisplayObjectContainer's children inherit a coordinate system that is rotated 90° counterclockwise. The object's coordinates refer to the registration point position.
Implementation
public function get x():Number
public function set x(value:Number):void
y | property |
y:Number
Language Version: | ActionScript 3.0 |
Product Version: | Flex 4 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Indicates the y coordinate of the DisplayObject instance relative to the local coordinates of the parent DisplayObjectContainer. If the object is inside a DisplayObjectContainer that has transformations, it is in the local coordinate system of the enclosing DisplayObjectContainer. Thus, for a DisplayObjectContainer rotated 90° counterclockwise, the DisplayObjectContainer's children inherit a coordinate system that is rotated 90° counterclockwise. The object's coordinates refer to the registration point position.
Implementation
public function get y():Number
public function set y(value:Number):void
