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

A TextFlow instance dispatches this event when the status of a FlowElement changes. This event can be used to detect when an inline graphic element has completed loading. You can use your event handler to recompose the text flow based on the presence of the newly loaded inline graphic element.

status

property 
status:String

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

The FlowElement's new status. The possible values of this property are defined by the InlineGraphicElementStatus class. There are five static constants available in the InlineGraphicElementStatus class:

  • ERROR : String = "error". An error occurred during loading of a referenced graphic.
  • LOADING : String = "loading". Load has been initiated (but not completed) on a graphic element that is a URL.
  • LOAD_PENDING : String = "loadPending". Graphic element is an URL that has not been loaded.
  • READY : String = "ready". Graphic is completely loaded and properly sized.
  • SIZE_PENDING : String = "sizePending". Graphic element with auto or percentage width/height has completed loading but has not been recomposed.



Implementation
    public function get status():String
    public function set status(value:String):void

Constructor Detail

StatusChangeEvent

()Constructor
public function StatusChangeEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = false, element:FlowElement = null, status:String = null, errorEvent:ErrorEvent = null)

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

Creates an event object that contains information about a status change.

Parameters
type:String — The type of the event. Event listeners can access this information through the inherited type property. There is only one type of StatusChangeEvent: StatusChangeEvent.INLINE_GRAPHIC_STATUS_CHANGE;
 
bubbles:Boolean (default = false) — Indicates whether an event is a bubbling event.This event does not bubble.
 
cancelable:Boolean (default = false) — Indicates whether the behavior associated with the event can be prevented. This event cannot be cancelled.
 
element:FlowElement (default = null) — The FlowElement instance that has experienced a change in status.
 
status:String (default = null) — The FlowElement instance's new status.
 
errorEvent:ErrorEvent (default = null) — The ErrorEvent object, if any, associated with the status.
Constant Detail

INLINE_GRAPHIC_STATUS_CHANGE

Constant
public static const INLINE_GRAPHIC_STATUS_CHANGE:String = "inlineGraphicStatusChange"

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

Defines the value of the type property of a inlineGraphicStatusChanged event object.

StatusChangeEvent_example.as

This example shows how to create an event handler that listens for the successful loading of an InlineGraphicElement object. The two key steps are to call the addEventListener() method on the text flow and to create an event handler function.

Call the addEventListener() method on the TextFlow instance. You can use the simple string "inlineGraphicsStatusChanged", but it is safer to use the static constant StatusChangeEvent.INLINE_GRAPHIC_STATUS_CHANGE

The event handler function in this example is named statusChangeHandler(). The event handler first checks to see whether the graphic is loaded. If the graphic is loaded, the event handler adjusts the height of the graphic to match that of the text. Finally, the event handler calls updateAllcontrollers() on the text flow to recompose and display the text and inline graphic.
