Ok, according to the examples already posted on this
list, the TreeView's style attribute can be used to draw
all the stuff provided by the gtk.Style class, such as
text, arrows, lines, etc. What I would like to have is 
the cellrenderer to display a real gtk widget, with
all it's functionality. Does anyone have an idea, how 
this can be done? The hard way would probably be to 
create all the stuff needed for such a widget as 
described above (gtk.Style) and then somehow set up 
some control functionality needed by the widget (don't 
know how yet and whether this is possible at that 
level). Using a gtk widget would of course make the 
whole thing a lot easier.

This implementation uses gtk.Windows to display the 
editors, which seems a possible solution for lists, 
but not for real trees where nodes must be expanded. 
And even for lists there are some problems, e.g., the 
windows displaying the editors (or other cell contents)
do not move if the window containing the treeview is 
moved.

thanks for any further hints,
Bernhard
