Flex4之创建自定义事件

首先申明：

<fx:Metadata>
  [Event(name="headerClick")]
</fx:Metadata>

然后注册这个事件：

var panelSkin:PanelSkin = skin as PanelSkin;

    panelSkin.addEventListener(MouseEvent.CLICK, onHeaderClick);

最后实现这个事件

  private function onHeaderClick(event:MouseEvent):void {
	if (event.currentTarget is PanelSkin) {
       var ps:PanelSkin = PanelSkin(event.currentTarget);
       if (event.localY < 30) {
         dispatchEvent(new Event("headerClick"));
       } 
     }
  }
