class UIObject
extends MovieClip

The UIObject class is the base class for all components and graphical objects. UIObjects support events and styles, and resize by scaling. The UIObject class itself is not used as an MXML tag.

Common MXML Syntax Inherited from UIObject

All user interface components in Flex extend the UIObject class. Flex components inherit the following properties from the UIObject class.

See Also
mx.events.EventDispatcher

invalidate

invalidate() : Void

Marks a component so that it is redrawn on the next frame interval.

invalidateProperties

invalidateProperties() : Void

If a property setter must do a lot of processing, it should wait to do that processing during the next measurement or layout cycle. That way, multiple changes to the same property do not cause that chunk of processing to execute multiple times. To defer processing, the component sets an internal flag and calls this invalidateProperties function. This function remembers that the component is "dirty", so you call the component`s commitProperties function after the current script finishes executing. When you call the commitProperties method, the component should check its internal flag. If the flag is set, it does that chunk of processing.

invalidateSize

invalidateSize() : Void

Called if the object`s size is changing. Because this object must be re-measured, there is a measurement and sizing pass after the current script finishes executing.

invalidateStyle

invalidateStyle(styleProp:String) : Void

Called if only styles are changing, so subclasses don`t have to redraw everything.

Parameters
styleProp - Style property.

measure

measure() : Void

Determines the size of the component. The UIObject class contains this code so it can be shared by the UIComponent and Label classes.

move

move(x:Number, y:Number, noEvent:Boolean) : Void

Moves the object.

Parameters
     x - Left position of the object.
     y - Top position of the object.
     noEvent - If true, it does not broadcast a move event.

redraw

redraw(bAlways:Boolean) : Void

Redraws the object instead of waiting for invalidation to do so.

Parameters
bAlways - If false, it does not redraw if not invalidated.

removeEventListener

removeEventListener() : 
		Void

Remove a listener for a particular event. The signature of this method is:
removeEventListener(event:String, listener) : Void

See Also
mx.events.EventDispatcher

setMask

setMask(mask_mc:MovieClip) : 
		Void

Overrides the MovieClip.setMask function, so it is possible to determine later whether this object has a mask.

Parameters
mask_mc - Mask that is currently applied to this object.

setSize

setSize(w:Number, h:Number, noEvent:Boolean) : Void

Sizes the object. The setSize method also sets the preferredWidth and preferredHeight parameters so that the layout managers do not resize the object to its original size.

Parameters
     w - Width of the object.
     h - Height of the object.
     noEvent - If true, it does not broadcast resize event.

setSizeNoLayout

setSizeNoLayout(w:Number, h:Number, noEvent:Boolean) : Void

Sizes the object. The setSizeNoLayout method does not set the preferredWidth and preferredHeight parameters, so a future layout calculation may result in the object returning to its previous size. This method is used primarily by Effects and Layout managers.

Parameters
     w - Width of the object.
     h - Height of the object.
     noEvent - If true, it does not broadcast resize event.

setStyle

setStyle() : 
		Void

Sets a style property. Use this method sparingly because it results in a lot of processing. This property is implemented in mx.styles.CSSSetStyle.as. The signature of this method is: setStyle(styleProp:String, newValue) : Void

swapDepths

swapDepths(target) : Void

Overrides the MovieClip.swapDepths function, so you can send an event when an object`s depth changes.

Parameters
target - UIObject to swap with.

Property Detail

alpha

alpha:Void  
    	[Write-Only]

Determines how transparent a component is. Values range from 0, which inidicates the component is invisible, to 100, which indicates the component is opaque. Device fonts do not honor alpha setting, although embedded fonts do. The default value is 100.

baselinePosition

baselinePosition:Number  
    	[Read-Only]

Determines the baseline y-coordinate of the first line of text of the component. Each component should override this property.

className

className:String

Name of component class. This property is also used in calculating style values. If _global.styles[className] exists, it set the defaults for a component.

depth

depth:Number  
    	[Read-Only]

The MovieClip depth of the UIObject instance, which determines the z-ordering.

descriptor

descriptor:Object  
    	[Read-Only]

Reference to the UIObjectDescriptor, if any, that was used by the createComponent method to create this UIObject instance. If this UIObject instance was not created from a descriptor, this property is undefined.

documentDescriptor

documentDescriptor:Object  
    	[Read-Only]

For a document object, which is an instance of a UIObject at the top of the hierarchy of a Flex application, MXML component, or ActionScript component, the documentDescriptor property is a reference to the descriptor at the top of the autogenerated descriptor tree for that document. For other UIObjects, it is undefined.

height

height:Number  
    	[Read-Write]

Number that specifies the height of the component, in pixels.

heightFlex

heightFlex:Number  
    	[Read-Write]

Setting to a positive number enables resizing of the component height. The default value is 0, which indicates that the component is not resizable.

id

id:String  
    	[Read-Write]

MXML ID of this UIObject INSTANCE. If no ID has been assigned, this property is the empty string.

instanceIndices

instanceIndices:Array

An Array that contains the indices required to reference a Repeater from its parent document. The Array is empty unless the Repeater is within one or more Repeaters. The first element corresponds to the outermost Repeater. For example, if the ID is "r" and instanceIndices is [2,4], you reference it on the document as r[2][4].

isDocument

isDocument:Boolean  
    	[Read-Only]

Determines whether this UIObject instance is a document object, that is, whether it is at the top of the hierarchy of a Flex application, MXML component, or ActionScript component.

kStretch

static kStretch:Number

Number used to indicate stretchability in the preferredWidth and preferredHeight.

maxHeight

maxHeight:Number  
    	[Read-Write]

Number that specifies the maximum height of the component, in pixels.

maxWidth

maxWidth:Number  
    	[Read-Write]

Number that specifies the maximum width of the component, in pixels.

minHeight

minHeight:Number  
    	[Read-Write]

Number that specifies the minimum height of the component, in pixels.

minWidth

minWidth:Number  
    	[Read-Write]

Number that specifies the minimum width of the component, in pixels.

mouseX

mouseX:Number  
    	[Read-Only]

Horizontal coordinate of the mouse pointer`s location in the coordinate system of this UIObject instance.

mouseY

mouseY:Number  
    	[Read-Only]

Vertical coordinate of the mouse pointer`s location in the coordinate system of this UIObject instance.

nestLevel

nestLevel:Number

Depth of this object in the containment hierarchy. This number is used by the measurement and layout code.

parentApplication

parentApplication:Object  
    	[Read-Only]

A reference to the Application object that contains this UIObject instance. This Application object might exist in a Loader in another Application, and so on, creating a chain of Application objects that can be walked using parentApplication. The parentApplication of an Application is never itself; it is either the Application into which it was loaded or undefined (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.

parentDocument

parentDocument:Object  
    	[Read-Only]

A reference to the parent document object for this UIObject. A document object is a UIObject at the top of the hierarchy of a Flex application, MXML component, or AS component. For the application object, parentDocument is undefined. 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.

preferredHeight

preferredHeight:Number  
    	[Read-Write]

Number that specifies the preferred height of the component, in pixels.

preferredWidth

preferredWidth:Number  
    	[Read-Write]

Number that specifies the preferred width of the component, in pixels.

repeaterIndices

repeaterIndices:Array

An array that contains the indices of the items in the dataProviders of the Repeaters in the parent document that produced this Repeater. The array is empty unless this Repeater is within one or more Repeaters. The first element 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]. This property differs from instanceIndices if the startingIndex of any of the Repeaters is not 0. For example, even if a Repeater starts at dataProvider item 4, the document reference of the first repeated object is b[0], not b[4].

scaleX

scaleX:Number  
    	[Read-Write]

Number that specifies the horizontal scaling percentage. The default value is 100.

scaleY

scaleY:Number  
    	[Read-Write]

Number that specifies the vertical scaling percentage. The default value is 100.

width

width:Number  
    	[Read-Write]

Number that specifies the width of the component, in pixels.

widthFlex

widthFlex:Number  
    	[Read-Write]
