insert widget in clist ?

["zawsh" <zawsh sinamail com>]

hi, 

I have an question about how to insert a GtkCombo widget (or other widget) into a cell in a clist ?

I can't find an api about how to do that . It seems that can only insert text or pixmap

into a cell.  maybe I forget something, have any idea about this problem . 

Thanks :)
