Intro
關於 ActionScript 的 addEventListener / dispatchEvent
這2個 method 被定義在 EventDispatcher
因此咱們的物件只要有繼承到這個, 都可以使用
講到 dispatchEvent 通常就應該是自定義event了
不然用 addEventListener 就夠了唄
Listener / Dispatch
這是自訂的類別
public class MyTest extends EventDispatcher
{
public static const Event_UnknownComplete:String="MyTest.Event_UnknownComplete";
public function doEvent_UnknownComplete():void{
this.dispatchEvent(new Event(Event_UnknownComplete));
}
public function start():void{
setTimeout(doEvent_UnknownComplete,2000);
}
}
在Application的測試Code
protected function application1_creationCompleteHandler(event:FlexEvent):void
{
var test : MyTest = new MyTest();
test.addEventListener(MyTest.Event_UnknownComplete, test_Event_UnknownComplete, false);
test.addEventListener(MyTest.Event_UnknownComplete, function(event:Event):void{
Alert.show("Event_UnknownComplete be dispatched 2");
});
test.start();
}
protected function test_Event_UnknownComplete(event:Event):void{
Alert.show("Event_UnknownComplete be dispatched 1");
}
