GtkTreeView / new cell renderer

[Elassadi t-online de (Mohamed Elassadi)]

Hi Volks 


I am trying to write a new cellrenderer that shows a combo widget after
the start_editing call

 
Well everything's goes fine and the entry is shown after the cell is
clicked ,
I have only one problem the button of the combo widget is not drawn, the
same thing happens if i try to implement 
a new cell renderer for optionmenu widget . the drawing routines of the
button widget seem to have problems
when inside a cell  ..


Please drop me line or 2 if you  have an Idea ..

By way is there some one who tried to write a similar widget

Thanks
