Re: Reparent tree iter

[Ian Liu <ian liu88 gmail com>]

Hey Kristian,

Thanks for the answer. The problem with the "cursor-move" event is that I was re-parenting
the row to the same "father" when the user clicked on it. This, obviously, "canceled" the

selection, because the original row which was clicked is now replaced by the copy.

Cheers,
Ian L.

As you have probably seen there are functions to reorder, swap or move
iterators in the same level.  There is no such functionality for moves
to different levels (re-parenting).  What you have been advised on the
IRC channel seems the easiest way for now.  (This is also how tree
view implements the drag and drop of a row to a difference place in
the tree).

What is the problem you are having with the "cursor-move" event?  Did
you mean the move-cursor event?
