JList returns null or -1

[sportacus]

Hi Guys,

I have a JList that I want to double click and get the String that is currently selected.However, the .getSelectedValue.toString keeps returning null or -1 even when I have a String selected.

My code is as follows:

    public void makeLstChatters(){
        //make the listener for the JList 
        MouseListener mouseListener = new MouseAdapter() {
            public void mouseClicked(MouseEvent e) {
                if (e.getClickCount() == 2) {  
                    try{
                        System.out.println(lstChatters.getSelectedValue().toString());
                        String str = lstChatters.getSelectedValue().toString();
                        serv.whisper(str, txtAreaMessage.getText());
                    }
                    catch(Exception ex){
                        ex.printStackTrace();
                    }
              }
            }
        };
        
        listModel = new DefaultListModel();

        lstChatters = new JList(listModel);

        JScrollPane scrollPane = new JScrollPane(lstChatters);
        lstChatters.addMouseListener(mouseListener);

can anyone see where I am going wrong?

Thanks a million!!

if (e.getClickCount() == 2) {
int index = list.locationToIndex(e.getPoint());
System.out.println("Double clicked on Item " + index);
}

then to get the string clicked...

listModel.get(index)
