Question

I was looking for a a JTree implementation, that contains checkboxes and which:

Answer 1

Can be solution without map structure.

MouseAdapter ml = new MouseAdapter() {
        public void mousePressed(MouseEvent e) {
            if ( e.getClickCount() == 1 )
            {
                TreePath selPath = m_xTree.getPathForLocation(e.getX(), e.getY());
                if(selPath==null) return;
                else if (selPath!=null && selPath.getPathCount()>=1)
                {
                    DataItem xDIClicked = (DataItem)( selPath.getPathComponent(selPath.getPathCount()-1) );
                    xDIClicked.setIsSelectedByCheckbox( !xDIClicked.getIsSelectedByCheckbox() );
                    m_xTree.repaint();
                }
            }
        }
    };
    m_xTree.addMouseListener(ml);

So xDIClicked returned by getPathComponent() is JTree Model's data item. And each DataItem contains checked property.
