图形皮肤的使用
1.在MXML标签中设置皮肤：
<mx:Button upSkin=”@ Embed(‘../assets/myFacyUpSkin.gif’)”>
2.在CSS块（或文件）中设置皮肤
<mx:Style>
Button {
overSkin: Embed( “../assets/myFacyUpSkin.gif”);
}
</mx:Style>
3.在ActionScript中设置皮肤
<mx:Script>
[Embed(“assets/myFancyDownSkin.gif”)]
var ds:Class;
function initApp(){
myButton.setStyle(“downSkin”, ds);
}
</mx:Script>
=========================================================
可编程的皮肤：
为了绘制可编程的皮肤,首先需要为新的皮肤类选择一个基类。Flex提供了3个类共你选择。
ProgrammaticSkin, Border, RectBorder.
下面是可编程的皮肤,举了一个小示例：
package my.yaner
{
import mx.skins.ProgrammaticSkin;
public class OrangeOval extends ProgrammaticSkin
{
protected override function updateDisplayList(w:Number, h:Number):void
{
var lineThickness:int = 4;
var backgroundFillColor:Number;
switch(name)
{
case "upSkin":
backgroundFillColor = 0xEA800C;
break;
case "overSkin":
backgroundFillColor = 0xF8B872;
break;
case "downSkin":
backgroundFillColor = 0xB06109;
break;
case "disabledSkin":
backgroundFillColor = 0xCCCCCC;
break;
}
graphics.clear();
graphics.beginFill(backgroundFillColor);
graphics.drawEllipse(0, 0, w, h);
graphics.endFill();
}
}
}
