TreeView/Treestore

[Mickael DREAN <mickael drean gmail com>]

Hi there,

 I've done a TreeStore which allow drag and drop. But, i would like to 
know how to move rows (like drag and drop in a way) without user 
interaction (just by calling a function)?

This is what it's look like :

   Elem 1  
      SElem 11
         SSElem 111
         SSElem 112
     SElem 12
        SSElem 121
  Elem2
      SElem 21
...

I would like to move SElem 11 (for example) with its children to Elem2 
so SElem 21 become SElem 22 and SElem 11 become SElem 21.
