GtkText inside GtkTree can't get input

[George Young <gry ll mit edu>]

[gtk+-1.2.8 / pygtk-0.6.6 / python1.5 / SuSE Linux]

I have GtkText widgets inside a GtkTree.
I can't seem to type into the text widgets... 
When I click on the text widget, the whole treeitem (or tree, I don't know)
highlights, which makes it's contents very hard to read.  Worse yet,
the gtktext widget doesn't accept text I type. 
I did 
        self.set_editable(1)
but it doesn't seem to help.

Maybe I need to abandon GtkTree and manage my own "+/-" button opening and closing widgets,
I don't need the full flexibility GtkTree provides anyway.  
Has anyone done something like this?
