The following example displays the Stage dimensions in a dynamically created text field.
When you resize the Stage, the values in the text field update. Create a button with an
instance name
remove_btn. Add the following ActionScript to Frame 1 of the Timeline.
this.createTextField("stageSize_txt", this.getNextHighestDepth(), 10, 10,
100, 22);
stageSize_txt.autoSize = true;
stageSize_txt.border = true;
var stageListener:Object = new Object();
stageListener.onResize = function() {
stageSize_txt.text = "w:"+Stage.width+", h:"+Stage.height;
};
Stage.addListener(stageListener);
remove_btn.onRelease = function() {
stageSize_txt.text = "Removing Stage listener...";
Stage.removeListener(stageListener);
}
Select Control > Test Movie to test this example. The values you see in the text field are
updated when you resize the testing environment. When you click
remove_btn, the listener is
removed and the values are no longer updated in the text field.
