Side note, to add to the discussion, here is a couple of ways to also update properties in code for <s:Skin> and <s:SparkSkin> with [1] and [2].
[1] override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void { doStuff(); super.updateDisplayList(unscaledWidth, unscaledHeight); } [2] // override public function styleChanged(styleProp:String):void { If (styleProper == "myStyleName") { doStuff(); } } -Mark K -----Original Message----- From: bilbosax <waspenc...@comcast.net> Sent: Sunday, December 29, 2019 10:27 PM To: users@flex.apache.org Subject: [Non-DoD Source] Re: Skins - Get Properties From Parent Component Alex, to be honest, I have become accustomed to avoiding binding expressions due to performance hits, especially with large array collections and dataproviders. I have become sooooo accustomed to doing this, that it didn't even cross my mind. But a binding expressions are brilliant in this situation and streamlines the process considerably, getting rid of two unneccessary methods and a timing mechanism that can't be 100% relied upon. Thanks for this simple but very useful solution. Here is what the skin code looks like now: <?xml version="1.0" encoding="utf-8"?> <s:SparkButtonSkin xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:fb="http://ns.adobe.com/flashbuilder/2009" minWidth="20" minHeight="20" alpha.disabled="0.5" xmlns:fxgAssets="fxgAssets.*"> <fx:Metadata> </fx:Metadata> <s:states> <s:State name="up" /> <s:State name="over" /> <s:State name="down" /> <s:State name="disabled" /> </s:states> <s:Rect id="buttonRect" width="100%" height="100%" bottomLeftRadiusX="{height/2}" bottomLeftRadiusY="{height/2}" bottomRightRadiusX="{height/2}" bottomRightRadiusY="{height/2}" topLeftRadiusX="{height/2}" topLeftRadiusY="{height/2}" topRightRadiusX="{height/2}" topRightRadiusY="{height/2}"> <s:fill> <s:SolidColor color.up="#2B8D00" color.down="#323233"/> </s:fill> </s:Rect> <s:Label id="labelDisplay" color="#FAFAFA" styleName="titleMedium" fontWeight="bold" horizontalCenter="0" verticalCenter="0"/> <s:Rect width="100%" height="100%" alpha="0" includeIn="up, over, down, disabled"> <s:fill> <s:SolidColor color="#FFFFFF"/> </s:fill> </s:Rect> </s:SparkButtonSkin> -- Sent from: http://apache-flex-users.2333346.n4.nabble.com/
