关于Flex背景渐变和皮肤动态切换的补丁
网上有代码可以实现背景渐变，但是在style动态切换的时候无效。
我hack了setupStyles()处的代码，可以使用了。

注意设置fillColors是十进制的颜色值。
比如:css = ".selector{fillColors: 12377400,9614128;}";

package application.view.components{import flash.display.*;import flash.geom.*;import flash.utils.*;import mx.containers.Canvas;import mx.core.EdgeMetrics;import mx.skins.halo.HaloBorder;import mx.utils.ColorUtil;import mx.utils.GraphicsUtil;public class SimpleGradientBorder extends HaloBorder {private var topCornerRadius:Number;// top corner radiusprivate var bottomCornerRadius:Number;// bottom corner radiusprivate var fillColors:Array;// fill colors (two)private var setup:Boolean;// ------------------------------------------------- //private function setupStyles():void{if ((this.parent as Canvas) != null){var str:String = (this.parent as Canvas).getStyle("fillColors");fillColors = str.split(",");}else{fillColors = getStyle("fillColors") as Array;}if (!fillColors) fillColors = [0xFFFFFF, 0xFFFFFF];topCornerRadius = getStyle("cornerRadius") as Number;if (!topCornerRadius) topCornerRadius = 0;bottomCornerRadius = getStyle("bottomCornerRadius") as Number;if (!bottomCornerRadius) bottomCornerRadius = topCornerRadius;}// ------------------------------------------------- //override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void{super.updateDisplayList(unscaledWidth, unscaledHeight);setupStyles();var g:Graphics = graphics;var b:EdgeMetrics = borderMetrics;var w:Number = unscaledWidth - b.left - b.right;var h:Number = unscaledHeight - b.top - b.bottom;var m:Matrix = verticalGradientMatrix(0, 0, w, h);g.beginGradientFill("linear", fillColors, [1, 1], [0, 255], m);var tr:Number = Math.max(topCornerRadius-2, 0);var br:Number = Math.max(bottomCornerRadius-2, 0);GraphicsUtil.drawRoundRectComplex(g, b.left, b.top, w, h, tr, tr, br, br);g.endFill();}}}
