}
private class ButtonHandler implements ActionListener {
@Override
public void actionPerformed(ActionEvent e) {
String output = "";
if (e.getSource() == button1) {
output = "plain button pressed.";
} else if (e.getSource() == button2) {
output = "icon button pressed.";
} else if (e.getSource() == button3) {
output = "button with icon and text pressed.";
}
JOptionPane.showMessageDialog(null, output);
}
}
public static void main(String[] args) {
JButtonDemo jbd = new JButtonDemo();
jbd.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
看到button3了吗是加文字和图片的说明，你可以试试，环境是在MyEclipse下运行的
你想改什么就改什么，图片上的字可以自己看看改吧。希望对你有所帮助！
