list.setVisibleRowCount(-1);
//list.setSize(new Dimension(30, 30));
list.addListSelectionListener(new AddaxFMSBodyListSelectionListener());
DragSelectionListener dragListener = new DragSelectionListener();
list.addMouseMotionListener(dragListener);
list.addMouseListener(dragListener);
PopUpListener popUp = new PopUpListener();
list.addMouseListener(popUp);
