如何将悬停效果放在jbutton上？

Question

我正在尝试创建一个Java桌面应用程序,我使用两个按钮.我想在这些按钮中添加悬停效果.我想:当我点击任何按钮时,它应该改变它的背景颜色.

我怎样才能实现它？

这是我的代码:

public class Party1Party2 extends JFrame
{
    JButton b1;
    JButton b2;
    Container pane;

    public Party1Party2()
    {
        getContentPane().setBackground(new java.awt.Color(255, 255, 255));

    b2.addActionListener(new ActionListener()
    {
        public void actionPerformed(ActionEvent ae)
        {
            JOptionPane.showMessageDialog(frame, "Welcome to allhabad High Court");
        }
    });

    b1.addActionListener(new ActionListener()
    {
        public void actionPerformed(ActionEvent ae)
        {
            JOptionPane.showMessageDialog(frame, "Welcome to allhabad High Court");

        }
    });
  }
}

你可以使用moused Entered和Exitedthe JButton,并做你想做的事.

例如:

jButton1.addMouseListener(new java.awt.event.MouseAdapter() {
    public void mouseEntered(java.awt.event.MouseEvent evt) {
        jButton1.setBackground(Color.GREEN);
    }

    public void mouseExited(java.awt.event.MouseEvent evt) {
        jButton1.setBackground(UIManager.getColor("control"));
    }
});
