How to consume JRadioButton select on mouse click doesn't seem to work

Question

I'm creating a very simple class to override Swing JRadioButton which allows a user to set a field determining whether or not the radio button is selectable.

public class SelectableRadio extends JRadioButton implements MouseListener
private boolean selectable = true;
public SelectableRadio()
{
    super();
    addMouseListener(this);
}

public void setSelectable(boolean select)
{
    selectable = select;
}

@Override
public void mousePressed(MouseEvent e)
{
    if (!selectable)
    {
        e.consume();
    }
}

All of the other methods are implemented. This does not work. When a SelectableRadio button is set as NOT selectable, the radio button is still selected when clicked.

Any help?

You'll need to change your setSelectable code, and add the following:

if (editable) {
    this.setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
    super.enableEvents(Event.MOUSE_DOWN | Event.MOUSE_UP);
} else {
    this.setCursor(CursorFactory.createUnavailableCursor());
    super.disableEvents(Event.MOUSE_DOWN | Event.MOUSE_UP);
}
