我正在尝试使用Java创建一个覆盖整个屏幕的全屏窗口。该窗口还必须具有一定的透明度（大约30%-50%的透明度）。当我说整个屏幕时，我的意思是它涵盖了所有内容（包括OSX/Linux/Windows中的坞站/任务栏/菜单栏），而当我说透明时，我指的是实时透明，而不仅仅是黑客截图。以下是我了解/尝试的内容：
所以我问这是否可以通过另一个我不知道的黑客来实现，那么我很高兴听到。
目标是在桌面上覆盖一个半透明的全屏。
.
GraphicsEnvironment.getLocalGraphicsEnvironment().getMaximumWindowBounds();

Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException:
The effects for full-screen windows are not supported.
