setLayoutMatrix(value:Matrix, invalidateLayout:Boolean):void

Sets the transform Matrix that is used to calculate the component's layout size and position relative to

its siblings.

setLayoutMatrix3D(value:Matrix3D, invalidateLayout:Boolean):void

Sets the transform Matrix3D that is used to calculate the component's layout size and position relative

to its siblings.

setStyle(styleProp:String, newValue:*):void

Sets a style property on this component instance.

setVisible(value:Boolean, noEvent:Boolean = false):void

Called when the visible property changes.

styleChanged(styleProp:String):void

Detects changes to style properties.

stylesInitialized():void

Flex calls the stylesInitialized() method when the styles for a component are first initialized.

suspendBackgroundProcessing():void

[static] Blocks the background processing of methods queued by callLater(), until

resumeBackgroundProcessing() is called.

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

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.

transformPointToParent(localPosition:Vector3D, position:Vector3D,

postLayoutPosition:Vector3D):void

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.

validateDisplayList():void

Validates the position and size of children and draws other visuals.

validateNow():void

Validate and update the properties and layout of this object and redraw it, if necessary.

validateProperties():void

Used by layout logic to validate the properties of a component by calling the commitProperties()

method.

validateSize(recursive:Boolean = false):void

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.

validationResultHandler(event:ValidationResultEvent):void

Handles both the valid and invalid events from a validator assigned to this component.

verticalGradientMatrix(x:Number, y:Number, width:Number, height:Number):Matrix

Returns a box Matrix which can be passed to drawRoundRect() as the rot parameter when drawing a

vertical gradient.
