Java Swing - 如何創(chuàng)建兩個JFrames并排
我們想知道如何創(chuàng)建兩個JFrames并排。
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;
public class Main {
static void createFrameAtLocation(Point p) {
JFrame frame = new JFrame();
frame.setTitle("Test frame on two screens");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel(new BorderLayout());
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) {
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);
}
}
