java - 双屏应用

Question

我必须在双屏模式下运行应用程序。如何在两个屏幕上作为独立窗口运行应用程序但共享相同的应用程序模型？

Answer 1

如果我没记错的话，这个例子可能对你有帮助。 首先将您的框架放在每个屏幕设备上。

frame1.setLocation(pointOnFirstScreen);
frame2.setLocation(pointOnSecondScreen);

最大化:

frame.setExtendedState(Frame.MAXIMIZED_BOTH);

工作示例:

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Frame;
import java.awt.GraphicsDevice;
import java.awt.GraphicsEnvironment;
import java.awt.Point;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextArea;
import javax.swing.SwingUtilities;

public class GuiApp1 {
protected void twoscreen() {
    Point p1 = null;
    Point p2 = null;
    for (GraphicsDevice gd : GraphicsEnvironment.getLocalGraphicsEnvironment ().getScreenDevices()) {
        if (p1 == null) {
            p1 = gd.getDefaultConfiguration().getBounds().getLocation();
        } else if (p2 == null) {
            p2 = gd.getDefaultConfiguration().getBounds().getLocation();
        }
    }
    if (p2 == null) {
        p2 = p1;
    }
    createFrameAtLocation(p1);
    createFrameAtLocation(p2);
 }

 private void createFrameAtLocation(Point p) {
    final JFrame frame = new JFrame();
    frame.setTitle("Test frame on two screens");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JPanel panel = new JPanel(new BorderLayout());
    final JTextArea textareaA = new JTextArea(24, 80);
    textareaA.setBorder(BorderFactory.createLineBorder(Color.DARK_GRAY, 1));
    panel.add(textareaA, BorderLayout.CENTER);
    frame.setLocation(p);
    frame.add(panel);
    frame.pack();
    frame.setExtendedState(Frame.MAXIMIZED_BOTH);
    frame.setVisible(true);
 }

 public static void main(String[] args) {
    SwingUtilities.invokeLater(new Runnable() {


        public void run() {
            new GuiApp1().twoscreen();
        }
    });
 }

}
