I've narrowed down the problem to a callback not getting called when the 
 key-press-event event occurs.  If I click off the field first the 
callback set the data with the "edited" event.  Then I can go back to 
the field and tab off and the data remains.

What I think I need to do is call g_signal_emit_by_name() in the 
key-press-event event callback, but I haven't gotten it working yet. 
The prototype from the gtk documentation is: 
g_signal_emit_by_name(gpointer instance, const gchar *detailed_signal, 
...);.  Can some explain the parameter to this?  I don't think I'm 
getting them right.  I think the instance is my treeview or renderer. 
The detailed-signal is in the form of "signal-name::detail"  which I 
know the signal is "edited" but what is the detail suppose to be?

Thanks,
