空中应用程序 - 在系统托盘中启动？

Question

如果有人可以帮助我，或者指出我正确的方向，我将不胜感激。

我一直在尝试在系统托盘中启动 adobe air 应用程序，到目前为止，我已经使用了这个 sn-p：http://www.swamicharan.com/blog/air/minimizing-an-air-app-to-systemtray/，它的工作原理与描述的一样，但是无论我做什么，我似乎都做不到让它在系统托盘中启动，最小化。这是我到目前为止的代码：

            public function loadTrayIcon():void{

我认为您可以通过在readyToTray(event:Event) 末尾调用dock() 来管理。 为确保您的 initialWindow 在启动时不可见，您可以在 application descriptor file 中将其 visible 属性设置为 false。
