Question

I have a set of JRadioButtons placed inside a JPanel.
Also I have a “delete” button, such that if a JRadioButton is selected and then this “delete” button is pressed, the JRadioButton should be deleted from the JPanel.

I tried this following (action listener for the delete button) but it didn’t work.

// bg: buttonGroup

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
    int count = -1;
    for (Enumeration e=bg.getElements(); e.hasMoreElements(); ) {
        JRadioButton b = (JRadioButton)e.nextElement();count++;
        if (b.getModel() == bg.getSelection()) {
            bg.remove(b);
            jPanel1.remove(jPanel1.getComponent(count)); 
        }
    }
}

Answer 1

Did you call

jPanel1.revalidate();
jPanel1.repaint();

after deleting?
