The y-coordinate of the baseline
of the first line of text of the component.
This property is used to implement
the baseline constraint style.
It is also used to align the label of a FormItem
with the controls in the FormItem.
Implementation public function get baselinePosition():Number
document
property
document:Object
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
A reference to the document object associated with this component.
A document object is an Object at the top of the hierarchy
of a Flex application, MXML component, or ActionScript component.
Implementation public function get document():Object public function set document(value:Object):void
enabled
property
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.
Implementation public function get enabled():Boolean public function set enabled(value:Boolean):void
explicitHeight
property
explicitHeight:Number
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
The explicitly specified height for the component,
in pixels, as the component's coordinates.
If no height is explicitly specified, the value is NaN.
Implementation public function get explicitHeight():Number public function set explicitHeight(value:Number):void
A single Sprite object that is shared among components
and used as an overlay for drawing the focus indicator.
Components share this object if their parent is a focused component,
not if the component implements the IFocusManagerComponent interface.
Implementation public function get focusPane():Sprite public function set focusPane(value:Sprite):void
Specifies whether this component is included in the layout of the
parent container.
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.
Implementation public function get includeInLayout():Boolean public function set includeInLayout(value:Boolean):void
isPopUp
property
isPopUp:Boolean
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
Set to true by the PopUpManager to indicate
that component has been popped up.
Implementation public function get isPopUp():Boolean public function set isPopUp(value:Boolean):void
maxHeight
property
maxHeight:Number [read-only]
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
Number that specifies the maximum height of the component,
in pixels, as the component's coordinates.
Implementation public function get maxHeight():Number
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
percentHeight
property
percentHeight:Number
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
Number that specifies the height of a component as a
percentage of its parent's size.
Allowed values are 0 to 100.
Implementation public function get percentHeight():Number public function set percentHeight(value:Number):void
percentWidth
property
percentWidth:Number
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
Number that specifies the width of a component as a
percentage of its parent's size.
Allowed values are 0 to 100.
Implementation public function get percentWidth():Number public function set percentWidth(value:Number):void
public function owns(displayObject:DisplayObject):Boolean
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
Returns true if the chain of owner properties
points from child to this UIComponent.
Parameters
displayObject:DisplayObject — A UIComponent.
Returns
Boolean — true if the child is parented or owned by this UIComponent.
parentChanged
()
method
public function parentChanged(p:DisplayObjectContainer):void
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
Called by Flex when a UIComponent object is added to or removed from a parent.
Developers typically never need to call this method.
Parameters
p:DisplayObjectContainer — The parent of this UIComponent object.
setVisible
()
method
public function setVisible(value:Boolean, noEvent:Boolean = false):void
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
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.
Parameters
value:Boolean — The new value of the visible property.
Specify true to show the component, and false to hide it.
noEvent:Boolean (default = false) — If 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.
