Display filename ToolTipText on JFileChooser

I have a JFileChooser.

I would like it to display a ToolTipText (which will be the filename) for each file in the JList, when the mouse points over it.

It looks that I will need to override JList::getToolTipText(), but I'm having trouble obtaining file chooser's list (and then overriding the getToolTipText() method).

I mean, do I have to create a new class that extends a JList, then override the method in that class, then replace file chooser's JList by the new class instance I made?

Do I need to access the JList ListModel attribute?

I made some research. These links might be useful:

This resolved my problem. Thanks to camickr for helping.

1- Use SwingUtils getDescendantOfType to obtain the list

2- Add a mouse listener to display ToolTipText

jList.addMouseMotionListener(new MouseMotionAdapter() {
        @Override
        public void mouseMoved(MouseEvent e) {
            JList l = (JList)e.getSource();
            ListModel m = l.getModel();
            int index = l.locationToIndex(e.getPoint());
            if( index>-1 ) {
                l.setToolTipText(m.getElementAt(index).toString());
            }
        }
    });
