Java 显示带任务栏的全屏 Swing 应用程序，没有标题栏 [英] Java show fullscreen swing application with taskbar without titlebar

问题描述

我需要开发一个没有标题栏的全屏GUI(我将使用边框布局设计页面开始作为我自己的标题)，还需要显示任务栏.我试过这个:

I need to develop a full-screen GUI without a title bar on it (I am going to use border layout design page start as my own title), also need to show the taskbar. I have tried this:

JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
frame.setUndecorated(true);
frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
frame.setVisible(true);

框架变为全屏，没有标题栏但隐藏任务栏.

Frame becomes full-screen without the title bar but hides the taskbar.

如果我更改为 frame.setUndecorated(false);框架变为全屏并显示任务栏，但标题栏没有消失

if I change to frame.setUndecorated(false); the frame becomes full-screen and taskbar is shown, but title bar doesn't disappear

我该如何解决?谢谢你.

How can I fix that? Thank you.
