Java - JList remove with double click

Devi

Hi, Trying to teach myself Java over the summer and was going well until I ran into this little problem. I have a Jlist and want to remove an Item when I double click it.

I see MouseListener doesnt have a method to deal with double click so I tried to make my own one in an inner class that extends the MouseAdapter class so I can use the getClickCount() method but for some reason nothing is happening, not even showing errors. Can anybody tell me why/ point me in the right direction?

public class RemoveSelectedItem extends MouseAdapter {
 
  public void mouseClicked(MouseEvent ev){
       JList list = (JList)ev.getSource();
       DefaultListModel listModel = (DefaultListModel)list.getModel();
 
           if (ev.getClickCount() == 2) {
              listModel.remove(list.getSelectedIndex());
           } 
 
 
   }
 
 
 }

Are you adding an instance of RemoveSelectedItem as a MouseListener to your list?

Have a look at the javadoc for JList for an example:

Yea that was it. When I looked at it again I realised I never added the instance of the listener to the jlist. Thanks for your reply.
