在我正在开发的应用程序中(在Java / swing中),我必须在用户的 second 屏幕上显示一个全屏窗口。 我使用类似于下面的代码来完成此操作... 是的,只要我在Windows资源管理器打开的窗口中单击,或者只要我打开Windows资源管理器(我使用的是Windows XP),全屏窗口就会最小化......
您是否知道解决此问题的方法或解决方法,或者是否有一些我不了解全屏窗口的重要内容?
感谢您的帮助,

通常,当应用程序处于“全屏”模式时,它将接管整个桌面。要让用户进入另一个窗口,他们必须使用alt-tab。此时,Windows将最小化全屏应用程序,以便其他应用程序可以到达前端。
这听起来像是Windows中的错误(未记录的功能......)。对于双屏设置,它可能不应该这样做。
解决此问题的一个选项是将窗口设置为“全屏”,而不是将窗口设置为与位置(0,0)的屏幕相同的大小。您可以从GraphicsConfigurations on the GraphicsDevice获取屏幕信息。

以下代码有效(谢谢John)。没有全屏和大“永远在上面”的窗口。 但我仍然不知道为什么窗户造成了这种奇怪的行为......
private Window initFullScreenWindow() {
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] gds = ge.getScreenDevices();
GraphicsDevice gd = gds[1];
JWindow window = new JWindow(gd.getDefaultConfiguration());
window.setContentPane(getJFSPanel());
window.setLocation(1280, 0);
window.setSize(gd.getDisplayMode().getWidth(), gd.getDisplayMode().getHeight());
window.setAlwaysOnTop(true);
//gd.setFullScreenWindow(window);
return window;
}
