JButton背景图片 [英] JButton background image

问题描述

您好我正在尝试为JButton实现Action侦听器，代码如下所示：

Hi i am trying to implement Action listener for JButton and code look like following:

ImageIcon imageForOne = new ImageIcon(getClass().getResource("resources//one.png"));
one = new JButton("",imageForOne);
one.setPreferredSize( new Dimension(78, 76));
one.addActionListener(myButtonHandler);

使用上面的JButton它看起来很好

Using the above JButton it looks fine

当我为按钮添加特定值时，例如

When i add specific value to button for e.g.

ImageIcon imageForOne = new ImageIcon(getClass().getResource("resources//one.png"));
//Check this
one = new JButton("one",imageForOne);
one.setPreferredSize( new Dimension(78, 76));
one.addActionListener(myButtonHandler);

如下图所示

我有什么方法可以避免这种情况并设置值。

Is there any way i can avoid this and set the value too.

感谢您的帮助。

推荐答案

就个人而言，我会使用 Action API 。

Personally, I would be using the Action API.

它将允许您定义动作命令的层次结构（如果这是您想要的）以及定义自包含的响应命令。

It will allow you defined a hierarchy of action commands (if that's what you want) as well as define self contained response to the commands.

你可以......

public class OneAction extends AbstractAction {
    public OneAction() {
        ImageIcon imageForOne = new ImageIcon(getClass().getResource("resources//one.png"));
        putValue(LARGE_ICON_KEY, imageForOne);
    }

    public void actionPerfomed(ActionEvent evt) {
        // Action for button 1
    }
}

然后您只需使用按钮...

Then you would simply use with your button...

one = new JButton(new OneAction());
one.setPreferredSize( new Dimension(78, 76));

例如......
