getLocationOnScreen of CellRect

[Isaac Hewitt]

I am using drag and drop. The user initiates a drag on a table cell. The size of the table cell is determined along with the text in that cell. A label is created which can be dragged across the glasspane.
The part that is not working correctly is the location on screen. The label when it appears on the glasspane appears very far to the left offscreen and obove the slected table cell. The purpose of this is for visual effect whilst dragging a film title to a text box. Here > frame.getGlasspane().setPoint(this.getLocationOnScreen(selected_Row));

 
private Point getLocationOnScreen(int selected_Row) {
          final Point tableLoc = this.getLocationOnScreen();
          final Rectangle cellRect = this.getCellRect(selected_Row, 0, true);
          tableLoc.x += cellRect.x;
          tableLoc.y += cellRect.y;
          return tableLoc;
    }

    public void dragGestureRecognized(DragGestureEvent e) {
      
        final int selected_Column = this.getSelectedColumn();
        if(selected_Column == 0) {
             final int selected_Row = this.getSelectedRow();
             final String title = this.getModel().getValueAt(selected_Row, 0).toString();
             
             final DVD_Titles frame = (DVD_Titles)SwingUtilities.getRoot(this);
             final JLabel label = new JLabel(title);
             Dimension d = this.getCellSize(selected_Row);
             label.setPreferredSize(d);
             BufferedImage img = new BufferedImage(d.width, d.height, BufferedImage.TYPE_BYTE_GRAY);
             Graphics2D gr = (Graphics2D)img.createGraphics();
             label.paint(gr);
             gr.dispose();

             label.addMouseListener(new GhostComponentAdapter(frame.getGlasspane(), "release"));
             label.addMouseMotionListener(new GhostMotionAdapter(frame.getGlasspane()));
             frame.getGlasspane().setPoint(this.getLocationOnScreen(selected_Row));
             frame.getGlasspane().setImage(img);
             frame.getGlasspane().repaint();
             frame.getGlasspane().setVisible(true);
