Java setFullScreenWindow（）保持在最顶层 [英] Java setFullScreenWindow() keep on top

问题描述

我正在编写一个旨在双显示器设置上运行的应用程序，其中DisplayJFrame在一台显示器上全屏显示，另一台显示器上显示ControlJFrame，向显示器发送指令。我尝试了两种不同的方法来设置全屏显示;每个人的成功似乎取决于操作系统。

  display.setUndecorated（true）; 
 display.setExtendedState（JFrame.MAXIMIZED_BOTH）; 
  

适用于Windows，但JFrame隐藏在OS X和Linux的dock / panels下。 / p>

我的另一种方法，利用

  GraphicsDevice.setFullScreenWindow（display）; 
  

适用于我尝试的所有三个操作系统，但在Windows中，将控制窗口聚焦在另一台显示器上使显示窗口隐藏，并调用

  display.setAlwaysOnTop（true）; 
  

无法解决问题。我有点偏向 GraphicsDevice 方法，因为我不必处理OS X或Linux中的问题，我希望Windows的问题是一个简单的修复。是吗？

解决方案

试试这个......

对于多屏幕

  GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment（）; 
 GraphicsDevice [] gs = ge.getScreenDevices（）; 
 
 
 //获取每个屏幕的大小
 
 for（int i = 0; i< gs.length; i ++）{
 DisplayMode dm = GS [I] .getDisplayMode（）; 
 int screenWidth = dm.getWidth（）; 
 int screenHeight = dm.getHeight（）; 
} 
  

使用 public final void setAlwaysOnTop（boolean alwaysOnTop）用于将窗口置于顶部，如果窗口可见，则包括将窗口带到前面，然后将其粘贴到最顶端的位置。

I'm writing an application that is intended to be run on a dual monitor setup, with a "Display" JFrame going fullscreen on one monitor and a "Control" JFrame on the other monitor, sending instructions to the Display. I've tried two separate methods of setting the Display fullscreen; the success of each seems to depend on the OS.

display.setUndecorated(true);
display.setExtendedState(JFrame.MAXIMIZED_BOTH);

Works in Windows, but the JFrame gets hidden under the dock/panels in OS X and Linux.

My other method, utilizing

GraphicsDevice.setFullScreenWindow(display);

Works in all three OSes that I tried, but in Windows, focusing the Control window on the other monitor makes the Display window hide, and calling

display.setAlwaysOnTop(true);

Doesn't fix the problem. I'm kind of partial to the GraphicsDevice method because I don't have to deal with the issues in OS X or Linux, and I'm hoping that the Windows problem is a simple fix. Is it?

解决方案

Try this...

For Multiple Screen

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] gs = ge.getScreenDevices();


// Get size of each screen

for (int i=0; i<gs.length; i++) {
    DisplayMode dm = gs[i].getDisplayMode();
    int screenWidth = dm.getWidth();
    int screenHeight = dm.getHeight();
}

Use public final void setAlwaysOnTop(boolean alwaysOnTop) for putting the window on top, If the window is visible, this includes bringing window toFront, then "sticking" it to the top-most position.
