[Gambas-user] Treeview HELL...

   Umm.. no I don't. See attached PNG. The list is sorted alphabetically 
and there is no 'parent' property available. The documentation for the 
treeviewitem virtual class agrees with what we see in the attached PNG, 
there is no Parent property. Was there ever a version that did not have 
the parent property in the treeviewitem class?

   I agree that this should require a recursive function to traverse the 
tree... as yet I have met with zero succcess using the methods 
available... I'll give it another whirl (what the heck.. I still have 
some hair left).
   The MoveBelow documentation does state it moves the internal cursor 
one 'visible' item below. So using this would require all nodes be 
expanded (just to be safe).
