我的目标是简化这段代码(一切正常):

package test;

import java.awt.Window;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.event.MouseMotionListener;
import javax.swing.JWindow;

public class A extends JWindow implements MouseListener, MouseMotionListener {

    public A() {
        addMouseListener(A.this);
        addMouseMotionListener(A.this);
    }

    @Override
    public void mouseClicked(MouseEvent e) {
    }

    @Override
    public void mousePressed(MouseEvent e) {
        //This method is being used, working fine
    }

    @Override
    public void mouseReleased(MouseEvent e) {
    }

    @Override
    public void mouseEntered(MouseEvent e) {
    }

    @Override
    public void mouseExited(MouseEvent e) {
    }

    @Override
    public void mouseDragged(MouseEvent e) {
        //This method is being …

我想将鼠标悬停在我的GUI(地图)上的一些JButton上,并显示该位置的名称,例如曼彻斯特和伦敦.我有一个按钮的代码,但它不适用于多个按钮,并打印out所有按钮位置的最后一条消息(因为我有10个按钮).

如果button1为true,则通过我的paintComponent()方法在指定区域中的GUI上绘制文本.

我该如何解决这个问题？

button1.addMouseMotionListener(this);
button2.addMouseMotionListener(this);

public void mouseMoved(MouseEvent arg0)
{
    if(button1.contains(arg0.getPoint()))
    {
        button1  = true;
        out = "test 1";
        repaint();
    }

    if(!button1.contains(arg0.getPoint()))
    {
        b1 = false;
        out = " ";
        repaint();
    }//same for all 10 buttons but change variables
}
