Adobe AIR提供Alert.show()。然而,這似乎如果像典型的例子托盤沒有頂層窗口失敗(「示例:創建不帶任何窗口的應用程序」):如何顯示沒有頂級窗口的警報框?
http://livedocs.adobe.com/flex/3/html/taskbar_1.html
我沒能進入Alert.show()工作在這個情況下。似乎也沒有alert()。
有沒有什麼辦法可以在這種情況下顯示警報提示(模態或非模態)而不需要重新發明輪子?
如空氣托盤應用程序框架:

注意「可見=假」必須保留,即使這是什麼造成的麻煩。
順便說一句,可以在AIR SDK示例文件夾中找到圖標。 – Tino 2011-01-27 05:26:38
