In the following example, I'm trying to get the rectangle of "theParent" from the perspective of "theGrandparent" (theParent.getRect(theGrandparent)). Here is the traced output:
0 0 100 250 0 0 100 100 I expected the rectangle of "theParent" to have a height of 100, which is its constrained height. Instead, the rectangle has a height of 250, presumably including the height of "theChild". So getRect() looks like its returning _content_ height and not _display_ height. Is this right? My application problem is that I'm trying to select all objects intersecting a selection rectangle. I was getting the rectangles of all children (using getRect) and calling intersects() on them. It was then that I noticed that children that scrolled were returning rectangles larger than their display area on the screen. What should I be doing instead? Build the rectangle myself with theParent.width and theParent.height? Example follows: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute" applicationComplete="onApplicationComplete(event)"> <mx:Script> <![CDATA[ import mx.events.FlexEvent; private function onApplicationComplete(e:FlexEvent):void { var theParentRect:Rectangle; theParentRect = theParent.getRect(theGrandparent); trace(theParentRect.x, theParentRect.y, theParentRect.width, theParentRect.height); trace(theParent.x, theParent.y, theParent.width, theParent.height); } ]]> </mx:Script> <mx:Canvas id="theGrandparent" width="200" height="200" backgroundColor="#00ff00"> <mx:Canvas id="theParent" width="100" height="100" backgroundColor="#0000ff"> <mx:Canvas id="theChild" width="50" height="250" backgroundColor="#ff0000"/> </mx:Canvas> </mx:Canvas> </mx:Application>
