我有一个中央数据库,我用JDBC连接它,在对数据进行一些准备之后,我生成了6个不同的JFrame,我喜欢在建筑物的不同墙壁上的不同显示器(显示器)上显示每个JFrame。我只能同时通过IP(通过WiFi)到达。我可以用GraphicsEnvironment以某种方式解决它吗?
我会很高兴任何建议!

如果操作系统可以将每个屏幕视为单独的图形设备,您应该可以使用类似的东西......
import java.awt.EventQueue;
import java.awt.GraphicsConfiguration;
import java.awt.GraphicsDevice;
import java.awt.GraphicsEnvironment;
import java.awt.Rectangle;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
public class TestGC {
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
}
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);
}
}
