Apache flex 从弹出窗口内部调用PopUpManager.removePopUp（）时，模式窗口动画中断

我有一个模式窗口，在打开和关闭时显示一个调整大小的动画，但有时在关闭时会闪烁

我找到了一件事。当我在窗口外单击时，关闭动画将正常播放。代码位于主应用程序中，位于mouseUpOutsideHandler方法中。这是对PopUpManager.removePopUp的简单调用。当我单击窗口内的close按钮时，它在窗口内的close方法中运行相同的代码PopUpManager.removePopUp，只是它先闪烁

除了在模态窗口实例中调用之外，它是完全相同的代码。看起来模态窗口正在淡出，然后被删除，然后播放“我的删除”动画。参见代码示例

可以稍后使用call进行修复

方法1

protected function close():void {
      //PopUpManager.removePopUp(this);
      callLater(PopUpManager.removePopUp, [this]);
}

方法2

function close(popUp:IFlexDisplayObject, endEffectsPlaying:Boolean = true) {
    if (popUp && popUp as IUIComponent && UIComponent(popUp).isEffectStarted) {
        if (endEffectsPlaying && popUp && popUp as IUIComponent) {
            EffectManager.endEffectsForTarget(popUp as IUIComponent);
        }

        // we exit out because if we continue, we would close the pop up.
        // but if we did that then when the effect ends it puts up a 
        // display object "shield" and there would be no way to close 
        // the display object shield since we removed the pop up 
        // display object that has our closing event listeners 
        return;
    }

    try {
        PopUpManager.removePopUp(popUp as IFlexDisplayObject);

    }
    catch (error:Error) {
        // sometimes the pop up is already closed or something 
        // or there's a bug in PopUpManager or EffectManager
    }
}

// The following code may be unrelated but it was
// in my pop up so it might be helping prevent an error
// i normally don't add unrelated code but it may help
protected function panel1_resizeHandler(event:ResizeEvent):void {
    if (stage && !addedEffect.isPlaying) {
        // to fix bug on line 505 of PopUpManagerImpl
        var popUpImp:PopUpManagerImpl = PopUpManagerImpl(Singleton.getInstance("mx.managers::IPopUpManager"));
        var popupInfo:Array = popUpImp.popupInfo;

        const n:int = popupInfo.length;
        var instanceIndex:int = -1;

        for (var i:int = 0; i < n; i++) {
            var o:PopUpData = popupInfo[i];
            if (o.owner == this) {
                instanceIndex = i;
            }
        }

        if (instanceIndex!=-1) {
            PopUpManager.centerPopUp(this);
        }
    }
}

此外，您还可以查看effects类是否适合您

手动调用隐藏/删除效果并侦听完整事件如何。然后在完整处理程序中删除弹出窗口。

// The following code may be unrelated but it was
// in my pop up so it might be helping prevent an error
// i normally don't add unrelated code but it may help
protected function panel1_resizeHandler(event:ResizeEvent):void {
    if (stage && !addedEffect.isPlaying) {
        // to fix bug on line 505 of PopUpManagerImpl
        var popUpImp:PopUpManagerImpl = PopUpManagerImpl(Singleton.getInstance("mx.managers::IPopUpManager"));
        var popupInfo:Array = popUpImp.popupInfo;

        const n:int = popupInfo.length;
        var instanceIndex:int = -1;

        for (var i:int = 0; i < n; i++) {
            var o:PopUpData = popupInfo[i];
            if (o.owner == this) {
                instanceIndex = i;
            }
        }

        if (instanceIndex!=-1) {
            PopUpManager.centerPopUp(this);
        }
    }
}
