本文介绍了一种在Adobe AIR应用程序中使窗口前置的有效方法。当点击系统托盘图标时，通常的方法无法使窗口前置到其他所有窗口之上。本文提供了一个解决此问题的方案：通过暂时设置窗口为始终在前，然后取消该设置。

While developing an AIR application, I had an issue with bringing the application to front (above all other windows) when clicking the systemTrayIcon.

Usually, you would use the method:

 
    1. 
    systemTrayIcon.addEventListener( "click" ,  function () {   
   
    2. 
    window.nativeWindow.orderToFront();   
   
    3. 
    });

But doing so will result in… actually nothing at all. The window doesn’t move.
Using the same code on a menu item of the SystemTrayIcon will work, but not on the click action of the Icon itself.

Workaround:

Set the window property alwaysInFront to true and then to false:

 
    1. 
    systemTrayIcon.addEventListener( "click" ,  function () {   
   
    2. 
      window.nativeWindow.alwaysInFront =  true ;   
   
    3. 
      window.nativeWindow.alwaysInFront =  false ;   
   
    4. 
      });
