我被按钮和按钮卡住了 预期结果…(所有信息均有效) 还有我所拥有的 我想替换这个:Java 将按钮更改为JButton can';我不能修理它(((,java,image,swing,button,jbutton,Java,Image,Swing,Button,Jbutton,我被按钮和按钮卡住了 预期结果…(所有信息均有效) 还有我所拥有的 我想替换这个: Button butRock = new Button("Rock"); butRock.addActionListener(this); ButtPan.add(butRock); 为此: BufferedImage buttonIcon = ImageIO.read(new File("rock.jpg")); JButton butRock = new JButton(new ImageIcon(but
Button butRock = new Button("Rock");
butRock.addActionListener(this);
ButtPan.add(butRock);
为此:
BufferedImage buttonIcon = ImageIO.read(new File("rock.jpg"));
JButton butRock = new JButton(new ImageIcon(buttonIcon));
butRock.addActionListener(this);
ButtPan.add(butRock);
我被卡住了,因为当我把按钮换成JButton时,程序不能正常工作……当我使用这个JButton时
问题:如何用图片替换按钮,程序仍能正常工作

问题是,您正在使用
getActionCommand
确定单击了哪个JButton
,但在Swing中默认情况下未设置此属性。您必须调用
butRock.setActionCommand("Rock");
java.awt.Button
如果未显式设置,则会自动将label属性用作ActionCommand
如果命令名为null(默认值),则此方法返回按钮的标签
一些旁白:
- 在整个应用程序中更好地避免和使用轻量级组件 当你的石头、剪纸、剪刀按钮具有相同的功能时,考虑使用.
- 通常使用直接实例
,而不是扩展类JFrame
- 使用
- 已弃用。请使用
Window\setVisible
- 不要使用
-查看更多系统。退出
