Stage.addListener()
Availability
Flash Player 6.
Usage
Stage.addListener( myListener:Object ) : Void
Parameters
myListener
An object that listens for a callback notification from the
Stage.onResize
event.
Returns
Nothing.
Description
Method; detects when a SWF file is resized (but only if
Stage.scaleMode = "noScale"
). The
addListener()
method doesn’t work with the default movie clip scaling setting (
showAll
) or
other scaling settings (
exactFit
and
noBorder
).
To use
addListener()
, you must first create a listener object . Stage listener objects receive
notification from
Stage.onResize
.
Example
This example creates a new listener object called
stageListener
. It then uses
myListener
to call
onResize
and define a function that will be called when
onResize
is triggered. Finally, the code
adds the
myListener
object to the callback list of the Stage object. Listener objects allow multiple
objects to listen for resize notifications.
this.createTextField("stageSize_txt", this.getNextHighestDepth(), 10, 10, 100,
22);
var stageListener:Object = new Object();
stageListener.onResize = function() {
stageSize_txt.text = "w:"+Stage.width+", h:"+Stage.height;
};
Stage.scaleMode = "noScale";
Stage.addListener(stageListener);
