Hey list, I'm trying to dynamically create a HSlider and add it as a child in the updateDisplayList method of a Canvas subclass.
When I do this, I get a run-time exception because the slider's updateDisplayList runs before the slider's commitPropertes (and commitProperties seems to set up some internal state that is needed by updateDisplayList). Is this a bug with sliders (I've used this strategy successfully for TextInput, ComboBox, etc), or is it just that updateDisplayList isn't the proper place to create and add child components? I don't think I can do it in createChildren, as I want to create the Slider based on properties that can be set after the Canvas is created. Simple test case: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script> <![CDATA[ import mx.controls.HSlider; private var theSlider:HSlider; override protected function updateDisplayList (unscaledWidth:Number, unscaledHeight:Number):void { super.updateDisplayList(unscaledWidth, unscaledHeight); if (theSlider) { removeChild(theSlider); theSlider = null; } theSlider = new HSlider(); theSlider.x = 100; theSlider.y = 100; addChild(theSlider); } ]]> </mx:Script> </mx:Application>
