 /**

  * This code is taken from the tutorial written by Jörn Hameister, <A

  * HREF="http://www.hameister.org/JavaSwingTreeTable.html">available here</A>.<BR/>

  * <BR/>

  * This class is a generic class. It has not been adapted for JUpload. It's directly taken from Jörn Hameister tutorial<BR/>

  * In order to allow the unfolding of the tree one, needs a AbstractCellEditor . That's why you put a class

  * MyTreeTableCellEditor to the AbstractCellEditor expanded and the TableCellEditor implemented interface. The only

  * function of the class MyTreeTableCellEditor is forwarding a double-click on the tree. In the method isCellEditable is

  * checked whether the first column ( column1 ) was clicked. If this is the case, a double click is on the tree forward,

  * so that the ExpansionListener can respond.
