将自定义组件放置在 Flex 4 中的 PopUp 窗口上（由 PopUpManager 调用）

如何在 PopUpManager 创建的 Popup 上显示自定义组件（在应用程序级别声明）？

在应用程序 mxml 中，我有以下代码片段：

private var myCustomComp:CustomComp = new CustomComp;

/** Called on by an event listener **/
protected function showCustomComp(event:MyEvent):void 
{
  myCustomComp.visible = true; 
  // place PopUpManager windows 
  this.setElementIndex(virtualKeyboard,this.numElements-1); // Also tried with 0 instead of numElements-1, but nothing! 
}

弹出窗口的调用方式如下：

PopUpManager.addPopUp(myPopup,FlexGlobals.topLevelApplication as DisplayObject,true, PopUpManagerChildList.APPLICATION);

无论如何，myCustomComp 不会显示在 PopUpManager 调用的任何窗口上。是否有任何快捷方式或者我应该使 myCustomComp 成为从 PopUpManager 调用的 PopUp 本身，以便它可以位于顶部？

你能给我一个提示吗？谢谢！

How can I display a custom component (declared at the Application level) over a Popup created by the PopUpManager?

At the Application mxml, I've the following pieces of code:

private var myCustomComp:CustomComp = new CustomComp;

/** Called on by an event listener **/
protected function showCustomComp(event:MyEvent):void 
{
  myCustomComp.visible = true; 
  // place PopUpManager windows 
  this.setElementIndex(virtualKeyboard,this.numElements-1); // Also tried with 0 instead of numElements-1, but nothing! 
}

The Popup window is called like this:

PopUpManager.addPopUp(myPopup,FlexGlobals.topLevelApplication as DisplayObject,true, PopUpManagerChildList.APPLICATION);

Anyway, myCustomComp is not showing over any window called by the PopUpManager. Is there any shortcut or should I make myCustomComp a PopUp itself called from the PopUpManager so it could be on top?

Could you give me a hint? Thanks!

试试这个，

private var myCustomComp:CustomComp = new CustomComp();

showCustomComp(event:MyEvent):void 
{
 mx.managers.PopUpManager.addPopUp(myCustomComp ,this,true);
 mx.managers.PopUpManager.centerPopUp(myCustomComp );
}

这应该会弹出 ua。告诉我，如果您仍然遇到任何问题

Try this,

private var myCustomComp:CustomComp = new CustomComp();

showCustomComp(event:MyEvent):void 
{
 mx.managers.PopUpManager.addPopUp(myCustomComp ,this,true);
 mx.managers.PopUpManager.centerPopUp(myCustomComp );
}

This should give u a popup. Tell me, if u are still facing any problem
