[英]Keep the jframe open on a dual monitor configuration in Java
I have a dual monitor configuration and I managed to open my Jframe
on the desired screen. 我具有双监视器配置,并且设法在所需的屏幕上打开了Jframe
。
But the problem is, every time I click on my main screen the other window minimizes, but I needed to always be on top. 但是问题是,每次我单击主屏幕时,另一个窗口都会最小化,但是我必须始终位于最上面。
PS: I checked the always on top check box PS:我选中了始终位于最前面的复选框
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] gs = ge.getScreenDevices();
that's how I'm using the other screen. 这就是我使用其他屏幕的方式。
As long as I use setFullScreenWindow I do get the same issue. 只要我使用setFullScreenWindow,我都会遇到相同的问题。 Replacing the frames by dialogs solves the issue but I guess you really want to have a frame, not a dialog. 通过对话框替换框架可以解决此问题,但我想您真的想拥有一个框架,而不是一个对话框。
So the solution is to manually maximize the frame instead of using setFullScreenWindow: 因此解决方案是手动最大化框架,而不是使用setFullScreenWindow:
import java.awt.*;
import javax.swing.*;
public class MultiMonitorFrame extends JFrame {
public static void showFrameOnScreen(Window frame, int screen) {
GraphicsEnvironment graphicsEnvironment = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] graphicsDevices = graphicsEnvironment.getScreenDevices();
GraphicsDevice graphicsDevice = ( screen > -1 && screen < graphicsDevices.length ) ? graphicsDevices[screen] : graphicsDevices.length > 0 ? graphicsDevices[0] : null;
if (graphicsDevice == null)
{
throw new RuntimeException( "There are no screens !" );
}
Rectangle bounds = graphicsDevice.getDefaultConfiguration().getBounds();
frame.setSize(bounds.width, bounds.height);
frame.setLocation(bounds.x, bounds.y);
}
public static void main(String[] args) {
JFrame frame1 = new JFrame("First frame");
frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame1.setVisible(true);
frame1.setAlwaysOnTop(true);
JFrame frame2 = new JFrame("Second frame");
frame2.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame2.setVisible(true);
frame2.setAlwaysOnTop(true);
showFrameOnScreen(frame1, 1);
showFrameOnScreen(frame2, 2);
}
}
This shows the two frames each on one monitor and the frames do not get minimized when using ALT-Tab or clicking on the desktop. 这样可以在一个监视器上显示两个帧,并且在使用ALT-Tab或单击桌面时,这些帧不会被最小化。
