Dragging the AIR application window around the screen - apache-flex

Question

I have an AIR application. It should be moved around the screen with the mouse. In order to achieve this I use the event:
this.stage.addEventListener(MouseEvent.MOUSE_DOWN, onMouseDown, true,-2);
It should be activated with the lowest priority compared to inserted elements for example those that should be scrolled, clicked, etc.
I tried the solution shown below with the event priority set to -1 because there might happen 2 different events and my moving application event should be the last one to be serviced or shouldn't be serviced at all.
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
width="200"
height="200"
applicationComplete="init()">
<fx:Script>
<![CDATA[
import mx.core.Window;
import mx.events.ScrollEvent;
private function init():void {
this.stage.addEventListener(MouseEvent.MOUSE_DOWN, onMouseDown, true,-2);
}
private function onMouseDown(event:MouseEvent):void {
trace("clicked on stage "+event.currentTarget.toString());
if(event.currentTarget == stage){
trace("catched stage target");
this.nativeWindow.startMove();
event.stopImmediatePropagation();
}
}
function scrolledCanvasHandler(event:ScrollEvent){
trace("clicked on canvas "+event.currentTarget.toString());
event.stopPropagation();
}
]]>
</fx:Script>
<mx:Canvas x="29" y="34" width="80%" height="80%" backgroundColor="#343434" scroll="scrolledCanvasHandler(event)">
<mx:Label x="25" y="77" text="moving window, moving window"
fontSize="18" color="#FFFFFF" fontWeight="bold"/>
</mx:Canvas>
</s:WindowedApplication>
As you will notice the
event.stopPropagation();
doesn't work.
Perhaps my solution isn't the best suited to achieve this. Are there better solutions?

Answer 1

that's what i did in an app of mine:
<s:HGroup id="appTitleBar"
width="100%" height="35"
styleName="titleBar"
mouseDown="nativeWindow.startMove();"
doubleClickEnabled="true"
doubleClick="nativeWindow.minimize();"
contentBackgroundColor="#313131"/>
click (+drag) on this HGroup will drag the window. duobleclick will minimize it.
edit
don't make your whole app draggable this will only confuse the user.
and btw priority should be positive not negative - but also don't mess with this. not expected behavior for anyone.
