stopImmediatePropagation不適用於SimpleButton

Question

我正在嘗試取消此actionscript3代碼中的事件：

public class Main extends Sprite
{
    public function Main()
    {

        this.addEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
    }

    protected function onAddedToStage(event:Event):void
    {
        this.addEventListener(MouseEvent.MOUSE_OVER, onOver, true, int.MAX_VALUE);

        var btn:SimpleButton = new SimpleButton(
            createBtnState(0x0000FF), 
            createBtnState(0x00FFFF),
            createBtnState(0x00FF00),
            createBtnState(0x0000FF));
        btn.x = stage.stageWidth - btn.width >> 1;
        btn.y = stage.stageHeight - btn.height >> 1;
        addChild(btn);
    }
    private function createBtnState(color:uint):Sprite
    {
        var s:Sprite = new Sprite();
        s.graphics.beginFill(color, 1);
        s.graphics.drawRect(0,0,100,20);
        s.graphics.endFill();
        return s;
    }

    protected function onOver(event:MouseEvent):void
    {
        event.stopImmediatePropagation(); //Don't work
    }
}

如何取消懸停按鈕的事件？ 在此示例中，當您將鼠標懸停時，按鈕會做出響應。

Answer 1

您的懸停事件似乎已添加到“主要”而不是“按鈕”上。 嘗試將事件偵聽器放在您聲明的btn上。

protected function onAddedToStage(event:Event):void
{
    //this.addEventListener(MouseEvent.MOUSE_OVER, onOver, true, int.MAX_VALUE);

    var btn:SimpleButton = new SimpleButton(
        createBtnState(0x0000FF), 
        createBtnState(0x00FFFF),
        createBtnState(0x00FF00),
        createBtnState(0x0000FF));
    btn.x = stage.stageWidth - btn.width >> 1;
    btn.y = stage.stageHeight - btn.height >> 1;
    addChild(btn);

    btn.addEventListener(MouseEvent.MOUSE_OVER, onOver, true, int.MAX_VALUE);
}
