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

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?
