Java中通过MouseMotionAdapter接口监听鼠标当前位置，然后将鼠标的位置信息通过Label显示出来。代码如下：
import java.awt.Frame;
import java.awt.Label;
import java.awt.TextField;
import java.awt.Color;
import java.awt.event.MouseEvent;
import java.awt.event.MouseMotionAdapter;
import java.awt.event.WindowEvent;
import java.awt.event.WindowAdapter;
public class TestAnonymousMonitor{
Frame f = new Frame("匿名内部类测试");
TextField tf = new TextField(30);
public TestAnonymousMonitor(){
f.add(new Label("请按下鼠标左键并拖动"), "North");
f.add(tf, "South");
f.addMouseMotionListener(new MouseMotionAdapter(){
public void mouseDragged(MouseEvent e) {
tf.setText("鼠标位置" + e.getPoint());
}
});
f.setBackground(Color.CYAN);
f.setSize(300, 200);
f.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e){
System.exit(0);
}
});
f.setVisible(true);
}
public static void main(String args[]) {
new TestAnonymousMonitor();
}
}效果图：
