The GraphicElement class represents a graphic element in a TextBlock or GroupElement object. Assign a GraphicElement object to the content property of a TextBlock object to display a graphic or an image with TextBlock.createTextLine(). Assign it to a GroupElement object to combine it with other graphic and text elements.

Property Detail

elementHeight

property
elementHeight:Number

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

The height in pixels to reserve for the graphic in the line. It is the responsibility of the caller to scale the graphic.

The default value is 15.0.



Implementation
    public function get elementHeight():Number
    public function set elementHeight(value:Number):void

elementWidth

property 
elementWidth:Number

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

The width in pixels to reserve for the graphic in the line. It is the responsibility of the caller to scale the graphic.

The default value is 15.0.



Implementation
    public function get elementWidth():Number
    public function set elementWidth(value:Number):void

graphic

property 
graphic:DisplayObject

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

The DisplayObject to be used as a graphic for the GraphicElement.

The default value is null.

When the GraphicElement becomes part of a text line, the graphic is added as a child of the line. Setting the graphic removes the old graphic from the line and adds the new one.



Implementation
    public function get graphic():DisplayObject
    public function set graphic(value:DisplayObject):void
Constructor Detail

GraphicElement

()Constructor
public function GraphicElement(graphic:DisplayObject = null, elementWidth:Number = 15.0, elementHeight:Number = 15.0, elementFormat:ElementFormat = null, eventMirror:EventDispatcher = null, textRotation:String = "rotate0")

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5

Creates a new GraphicElement instance.

The registration point of the graphic aligns with the upper-left corner of the region defined by elementHeight, elementWidth and elementFormat.baselineShift. The graphic is not scaled to match the size of the region. If the GraphicElement has an eventMirror, the elementWidth and elementHeight properties, and not the graphic, determine the size and position of the resulting mirror region. If a loader is used, the graphic might not be loaded at the time the text line and the mirror regions are created.

Parameters
graphic:DisplayObject (default = null) — The DisplayObject to populate the GraphicElement. The default value is null.
 
elementWidth:Number (default = 15.0) — The width of the area reserved for the element in pixels. The default value is 15.
 
elementHeight:Number (default = 15.0) — The height of the area reserved for the element in pixels. The default value is 15.
 
elementFormat:ElementFormat (default = null) — The element format for the element. The default value is null.
 
eventMirror:EventDispatcher (default = null) — The EventDispatcher object that receives copies of every event dispatched to text lines created based on this content element. The default value is null.
 
textRotation:String (default = "rotate0") — The rotation applied to the element as a unit. Use flash.text.engine.TextRotation constants for this property. The default value is flash.text.engine.TextRotation.ROTATE_0.

GraphicElementExample.as

The following example creates a TextBlock with a GraphicElement (a red box) and displays it, adding a second TextBlock beneath it that contains a caption.
