[flexcoders] Re: how to use stage in mxml
I try this
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; layout=absolute
creationPolicy=all creationComplete=init()
mx:Script
![CDATA[
import mx.events.ResizeEvent;
private function init():void{
stage.scaleMode = StageScaleMode.NO_SCALE;
}
]]
/mx:Script
...
...
/mx:Application
I also get error:
TypeError: Error #1009: Cannot access a property or method of a null object
reference.
Thanks for help
Mark
[flexcoders] Re: how to use stage in mxml
The stage isn't available immediately. That's why you get a null error.
With a little trickery:
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
creationComplete=onCreationComplete()
resize=getStageDimensions()
mx:Script
![CDATA[
private function onCreationComplete():void
{
callLater( getStageDimensions );
}
private function getStageDimensions():void
{
if ( stage )
{
trace( height: + stage.height );
trace( width: + stage.width );
}
}
]]
/mx:Script

Btw, adding a new topic every few hours that addresses the same issue, but with
a slightly different name, is really bad form.

[flexcoders] Re: how to use stage in mxml
Why not just use the addedToStage event instead? This will guarantee that stage
is not null.
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
addedToStage=init();
public function init():void
{
stage.addEventListener(Event.RESIZE, resizeHandler);
}
private function resizeHandler(event:ResizeEvent):void
{
trace(height: + stage.height);
trace(height: + stage.width);
}
