[Laszlo-dev] For Review: Change 20090302-hqm-y Summary: catch and forward mouse clicks from TextField

[André Bargull]

I got a stack-overflow which crashed the Player/Browser when I used your 
change (I clicked somewhere on the debugger).
And I think the "__forwardMouseEventToSprite" function needs to be 
adjusted, because:
- it's possible that other non-mouseEnabled sprites are on top of the 
TextField in which case length-2 won't work
- the event needs to be forwarded to the next mouseEnabled sprite

And the handcursor is not shown in the second testcase at LPP-7551 when 
you move the mouse over the text. (I don't know how to fix that, though.)

Here's an updated version:

function __forwardMouseEventToSprite(e:MouseEvent):void {
     var tfound:Boolean = false;
     var objs:Array = LFCApplication.stage.getObjectsUnderPoint(new 
Point(e.stageX, e.stageY));
     for (var i:int = objs.length - 1; i >= 0; --i) {
         var obj:DisplayObject = objs[i];
         if (! tfound) {
             tfound = (obj === this.textfield);
         } else if (obj is InteractiveObject) {
             var iobj:InteractiveObject = InteractiveObject(obj);
             if (iobj.mouseEnabled) {
                 iobj.dispatchEvent(e);
                 break;
             }
         }
     }
}
