Please review the documentation on creating custom components. Measure() is called before updateDisplayList(). Overriding the width setter is not recommended.

I created my own component that extends UIComponent, that draws rectangle shape. I overrided the seter for width that when i set new width, the object redraw itself. When this is done, i check the witdh of the object, it returns me old width for one action back. I overrided measure function. ******************************************************** Some of the code: ******************************************************** private function render(_arg_w:Number = 20,_arg_h:Number = 20):void{ rectSprite.graphics.lineStyle(1); rectSprite.graphics.beginFill(cfill, 1); rectSprite.graphics.drawRect(0,0,_arg_w,_arg_h); addChild(rectSprite); //set mesaures invalidateSize( ); } override protected function measure( ):void { super.measure( ); measuredHeight = measuredMinHeight = rectSprite.height; measuredWidth = measuredMinWidth = rectSprite.width; } override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void { super.updateDisplayList(unscaledWidth,unscaledHeight); } [Bindable] override public function set width(_arg_w:Number):void{ //change width if number is passed if(_arg_w && rectSprite !== null){ rectSprite.graphics.clear(); render(_arg_w); }else{ trace("no data inserted"); } } ********************************************************* Thanks for help, Toni
