Java Swing - 如何在不同的顯示器上創(chuàng)建不同的JFrames
我們想知道如何在不同的顯示器上創(chuàng)建不同的JFrames。
import java.awt.GraphicsConfiguration;
import java.awt.GraphicsDevice;
import java.awt.GraphicsEnvironment;
import java.awt.Rectangle;
import javax.swing.JFrame;
import javax.swing.JLabel;
public class Main {
public static void main(String[] args) {
GraphicsDevice[] sds = GraphicsEnvironment.getLocalGraphicsEnvironment()
.getScreenDevices();
for (GraphicsDevice sd : sds) {
System.out.println(sd.getIDstring());
GraphicsConfiguration gc = sd.getDefaultConfiguration();
JFrame f = new JFrame(gc);
f.add(new JLabel(sd.getIDstring()));
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.pack();
centerOn(f, gc);
f.setVisible(true);
}
}
private static void centerOn(JFrame f, GraphicsConfiguration gc) {
Rectangle bounds = gc.getBounds();
int x = bounds.x + ((bounds.width - f.getWidth()) / 2);
int y = bounds.y + ((bounds.height - f.getHeight()) / 2);
f.setLocation(x, y);
}
}
