我在玻璃窗格下有一些带有两个图像的代码。我想让每个图像都在它自己的玻璃窗格下，并且每个玻璃窗格都发出它自己的鼠标监听器的信号。目前，我将它们都制作在一个玻璃窗格下，一个鼠标监听器用于整个玻璃窗格。两个图像并排在网格布局中，因此将玻璃窗格分成两半应该不会太难。这是一个玻璃窗格的代码，但请注意，我正在尝试制作两个玻璃窗格，并为每个图像制作两个单独的鼠标侦听器类。这只是带有一个*两个图像的鼠标侦听器的代码：
package Buttons;
import java.awt.GridLayout;
import java.awt.event.*;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.event.MouseMotionListener;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JDialog;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class Giraffewindow extends JDialog {
public Giraffewindow() {
JDialog giraffewindow = new JDialog();
Icon giraffe = new ImageIcon(getClass().getResource("giraffe.png"));
Icon windows = new ImageIcon(getClass().getResource("windows.png"));
giraffewindow.setLayout(new GridLayout(1, 2, 0, 0));
giraffewindow.add(new JLabel(windows));
giraffewindow.add(new JLabel(giraffe));
giraffewindow.pack();
giraffewindow.setTitle("GIRAFFE!");
giraffewindow.setVisible(true);
giraffewindow.setDefaultCloseOperation(DISPOSE_ON_CLOSE);
JPanel glass = ((JPanel) giraffewindow.getGlassPane());
glass.setVisible(true);
status = new JLabel("I can change");
glass.add(status);
glass.setLayout(null);
giraffemousehandler giraffemouse = new giraffemousehandler();
glass.addMouseListener(giraffemouse);
glass.addMouseMotionListener(giraffemouse); //Can I add mouse motion listener to a picture
// setLayout(null);
}
JLabel status = null;
class giraffemousehandler extends MouseAdapter implements MouseListener, MouseMotionListener { //MouseAdapter makes it so that you don't have to have all 7 implemented mouse listener methods
@Override
public void mouseMoved(MouseEvent e) {
// TODO Auto-generated method stub
status.setBounds(e.getX(), e.getY(), 50, 60); //Makes JLabel follow mouse
}
@Override
public void mouseEntered(MouseEvent e) {
status.setText("Enter);
}
@Override
public void mouseExited(MouseEvent e) {
status.setText("Exit");
// status.setBounds(e.getX(), e.getY(), 5, 6);
}
}
}
这是camickr请求的代码，请注意有两个单独的鼠标侦听器，我很想知道如何做到这一点。当 JLabel 跟随鼠标时，1）它离鼠标非常远，2）它不显示完整的 JLabel 和 3）它在一次退出/进入后不会改变。我非常感谢您的帮助，这是基于 camickrs 建议的代码：
