设置JFrame而不与任务栏重叠 [英] Setting a JFrame without overlapping with taskbar

问题描述

我需要有一个未修饰的JFrame（ setUndecorated（true） ），需要全屏显示，而不会与任务栏重叠。

I need to have a undecorated JFrame(setUndecorated(true)) which need to be shown fullscreen, without overlapping with the taskbar.

我尝试过以下解决方案。

I have tried the below solutions.

• 调用setExtendedState（MAXIMIZED_BOTH）。

• Calling setExtendedState(MAXIMIZED_BOTH).

• 优势：
  这样可以正常工作，即窗口会动态调整，除非它有以下问题。


• 问题
  最初窗口占据全屏
  虽然框架会动态调整，但它与任务栏重叠。

• Advantage: This works fine as expected, i.e., the window is getting adjusted itself dynamically, except it has the below issues.
• Issues Initially the window occupies the fullscreen Though the frame get adjusted itself dynamically, it overlaps with the taskbar.

按照 JFrame.setExtendedState（MAXIMIZED_BOTH）是否与未修饰的帧一起使用？

 GraphicsConfiguration config = aFrame.getGraphicsConfiguration();
 Rectangle usableBounds = SunGraphicsEnvironment.getUsableBounds(config.getDevice());
 aFrame.setBounds(0, 0, usableBounds.width, usableBounds.height);

• 优势：
  我没有重叠，窗口看起来很好。


• 问题：
  当任务栏位置/大小发生变化时，窗口不会动态调整自身。


• Advantage: I am not getting overlaps and window looks fine.
• Issue: Window is not adjusting itself dynamically when the taskbar position/size is changed.

我们非常感谢任何帮助。

Any help would be greatly appreciated.

我想到了一个设计。但不确定其可行性。我可以使用setBounds（）。但是，当调整任务栏或重新定位任务栏时，我需要通知我的框架。有办法吗？

I thought of a design. But not sure about its feasibility. I can use the setBounds(). But then I need my frame to be notified when the task bar is adjusted or repositioned. Is there a way?

推荐答案

能够使用以下代码解决上述问题，

Able to able to fix the above issue with the below code,

Rectangle usableBounds = SunGraphicsEnvironment.getUsableBounds(config.getDevice());
setMaximizedBounds(usableBounds);
setExtendedState(MAXIMIZED_BOTH);

所以通过 getUsableBounds 我能够得到离开任务栏的界限。因此我使用 setExtendedState（MAXIMIZED_BOTH）当我重新调整/重新定位任务栏时，窗口会自动更新。 ： - ）

So by getUsableBounds I am able to get the bounds leaving the taskbar. And hence I am using setExtendedState(MAXIMIZED_BOTH) the window is getting updated automatically when I re-size/re-position the taskbar. :-)
