如果可能，将jFrame输出到第二个监视器 [英] Output jFrame to second monitor if possible

问题描述

我在Java上有一个关于Swing的jFrame，如果这个监视器存在，我希望它输出到第二个监视器。

i have a jFrame on Swing in Java, and i want it to output to second monitor, if this monitor exists.

我试过这个（通过此页面）以获取显示分辨率

I tried this (by this page) to get resolutions of displays

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] gs = ge.getScreenDevices();
for (int j = 0; j < gs.length; j++)
{
    GraphicsConfiguration[] gc =  gs[j].getConfigurations();
    for (int i = 0; i < gc.length; i++)
    {
        Rectangle gcBounds = gc[i].getBounds();
        int xoffs = gcBounds.x;
        int yoffs = gcBounds.y;
    }
}         

然后我在调试器中看到xoffs和yoffs for
我的第一台显示器（1360 * 768）xoffs = 1360和yoffs = 0
秒显示器（1280 * 1024）xoffs = 0和yoffs = 0

But then i watch in debugger to xoffs and yoffs for my first monitor (1360*768) xoffs = 1360 and yoffs = 0 second monitor (1280*1024) xoffs = 0 and yoffs = 0

我做错了什么？

推荐答案

请尝试以下方法：

public static void main( String[] args )
{
   java.awt.GraphicsDevice[] devices = GraphicsEnvironment.getLocalGraphicsEnvironment().getScreenDevices();

   for ( int i = 0; i < devices.length; i++ )
   {
      System.out.println( "Device " + i + " width: " + devices[ i ].getDisplayMode().getWidth() );
      System.out.println( "Device " + i + " height: " + devices[ i ].getDisplayMode().getHeight() );
   }
}
