java的模態框架

Question

我不知道是否有可能：

1. 做一個JDialog（可模態）與最大化按鈕（就是可以進行自定義，但是這將最大限度地提高幀？）
2. 或使jframe（其中有默認最大化按鈕）模式？

有很多關於此的話題，但我沒有找到乾淨的解決方案。只有技巧與setEnabled（）等。

謝謝大家提前！

Answer 1

• AFAIK不可能的，因爲頂層容器從本地OS來了，

• 再用鼠標雙擊JFrame中的工具欄調整容器填滿整個屏幕尺寸，第二雙擊還原lastz已知尺寸

• 這不可能與JDialog

• 任何鼠標（XXX）監聽器確實從工具欄不響應mouse_events從本地OS來，僅從是填充的rootPane

請看看這個，你可以在你的問題中使用JDialog。
