Java 将JPanel添加到ActionListener
我已经创建了一个JPanel,上面有我需要的所有JRadioButtons(称为PortSettings)。我还有一个按钮,叫做端口设置,当用户单击该按钮时,我需要JPanel出现并显示单选按钮。我曾尝试将JPanel添加到actionlistener,但没有成功。我的代码如下。我已从除portsettings按钮之外的其他按钮中删除了所有其他ActionListener。如果这个问题让人困惑,我很抱歉。很难解释我需要做什么。我已经上传了面板的外观图以及我的程序截图Java 将JPanel添加到ActionListener,java,swing,jpanel,actionlistener,jradiobutton,Java,Swing,Jpanel,Actionlistener,Jradiobutton,我已经创建了一个JPanel,上面有我需要的所有JRadioButtons(称为PortSettings)。我还有一个按钮,叫做端口设置,当用户单击该按钮时,我需要JPanel出现并显示单选按钮。我曾尝试将JPanel添加到actionlistener,但没有成功。我的代码如下。我已从除portsettings按钮之外的其他按钮中删除了所有其他ActionListener。如果这个问题让人困惑,我很抱歉。很难解释我需要做什么。我已经上传了面板的外观图以及我的程序截图 import java.aw

我曾尝试将JFrame添加到ActionListener,然后将JPanel添加到JFrame,但单击端口设置按钮时,什么也没有发生。另外,当我试图将JPanel添加到JFrame时,它告诉我将final放在JPanel PortSettings=new JPanel();。这是代码

只需将动作侦听器添加到所有按钮。 像这样:
yourButton.addActionListener(this);
对所有按钮都这样做
然后使用TestPalication类的actionPreformed方法执行以下操作:
@Override
public void actionPerformed(ActionEvent arg0) {
((JRadioButton) arg0.getSource()).setTitle("Clicked!");
}
您的问题有点让人困惑,但我希望这能澄清一点。您的思路是正确的,但您不想将
PortSettings
面板添加到新的JFrame
面板,而是添加到先前构建的面板的某个位置,分配给局部变量frame
。所以你的行动听众应该
portsettings.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
frame.add(PortSettings, BorderLayout.SOUTH);
frame.pack();
}
});
(这是假设您确实希望在该时刻将其添加到帧中,而不是从一开始就以不可见的方式添加并使其可见,如@Aleksei建议的那样。)
关于final
的错误消息是因为您在(匿名)内部类中使用了PortSettings
,即ActionListener
。在我建议的修改中,框架
,同样适用,因此您还需要修改其声明:
final JFrame frame = new JFrame();
原因是相当技术性的,而且现在离题了:就这么做吧
如果希望面板显示在单独的窗口中,则需要一个JDialog
,而不是第二个JFrame
:
portsettings.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
JDialog dialog = new JDialog(frame);
dialog.add(PortSettings);
dialog.pack();
dialog.setVisible(true);
}
});
查看
JOptionPane
类,了解从对话框中获得更多功能的丰富方法选择。可能是我不懂一些东西,但可能是在这个JFrame上制作一些带有按钮的JPanel,让它们可见或不可见会更好。当我单击按钮portsettings时,我需要打开面板端口设置。我刚刚贴了一张照片,上面是我布置好面板后的样子。
