JRadionButton自动取消选择

Question

我有一个jframe,它包含两个JRadioButton.

public class jradioButtontest extends javax.swing.JFrame {

public jradioButtontest() {
    initComponents();
}

@SuppressWarnings("unchecked")
// <editor-fold defaultstate="collapsed" desc="Generated Code">
private void initComponents() {

    jRadioButton1 = new javax.swing.JRadioButton();
    jRadioButton2 = new javax.swing.JRadioButton();

    setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

    jRadioButton1.setText("jRadioButton1");

    jRadioButton2.setText("jRadioButton2");

    javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
    getContentPane().setLayout(layout);
    layout.setHorizontalGroup(
        layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addGroup(layout.createSequentialGroup()
            .addGap(198, 198, 198)
            .addGroup(layout.createParallelGroup(javax.swing.GroupLayout.Alignment.TRAILING)
                .addComponent(jRadioButton2)
                .addComponent(jRadioButton1))
            .addContainerGap(203, Short.MAX_VALUE))
    );
    layout.setVerticalGroup(
        layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addGroup(layout.createSequentialGroup()
            .addGap(80, 80, 80)
            .addComponent(jRadioButton1)
            .addGap(18, 18, 18)
            .addComponent(jRadioButton2)
            .addContainerGap(225, Short.MAX_VALUE))
    );

    pack();
}// </editor-fold>

public static void main(String args[]) {
    java.awt.EventQueue.invokeLater(new Runnable() {
        public void run() {
            new jradioButtontest().setVisible(true);
        }
    });
}
// Variables declaration - do not modify
private javax.swing.JRadioButton jRadioButton1;
private javax.swing.JRadioButton jRadioButton2;
// End of variables declaration
}

我希望当我选择第一个JRadioButton时,应该取消选择其他JRadioButton.我使用ready jframe,如何更改netbeans生成的代码？这是怎么回事？

Answer 1

默认情况下,在自己的ButtonGroup中创建一个新的JRadioButton,这意味着它们都可以独立选择.

如果您希望链接两个按钮,以便一次只能选择一个,则需要添加:

ButtonGroup group = new ButtonGroup();
group.add(jRadioButton1);
group.add(jRadioButton2);

构建按钮后.
