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

问题描述

我需要一个未装饰的 JFrame(setUndecorated(true))，它需要全屏显示，不与任务栏重叠.

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

我已经尝试了以下解决方案.

I have tried the below solutions.

• 调用 setExtendedState(MAXIMIZED_BOTH).

• Calling setExtendedState(MAXIMIZED_BOTH).

• 优势:这可以按预期正常工作，即窗口正在动态调整，但存在以下问题.
• 问题最初窗口占据全屏虽然框架会自行动态调整，但它会与任务栏重叠.

• 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.

尝试了 Does JFrame 中所述的以下解决方案.setExtendedState(MAXIMIZED_BOTH) 是否适用于未装饰的框架?

 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:更改任务栏位置/大小时，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.

任何帮助将不胜感激.

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

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

能够用下面的代码解决上述问题，

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 我可以得到离开任务栏的边界.因此我使用 setExtendedState(MAXIMIZED_BOTH) 当我重新调整任务栏的大小/重新定位时，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. :-)
