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"); } }); } }
解决方法
你可以使用鼠标输入和退出JButton,并做任何你想要的.
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")); } });
