* Intended usage is like this:
*
*
*
ActionFlagsTableCell aftc = new ActionFlagsTableCell();
*
col = new TableColumn(0);
*
col.setCellRenderer(aftc);
*
col.setCellEditor(aftc);
*
* Note: Do not use the same object both as TableCellRenderer and
* TableCellEditor - this can mess up the current editor component
* by subsequent calls to the renderer (#19995 and #12462).
