Since no-one appears to have replied here is my meagre help.

No idea.  I doubt it is automatic; I guess you will need to do it 
yourself.

See section 9 of the GTK+ 2.0 Tree View tutorial. (esp. 9.2)
I see that this was a capability that was present in the old 
CTree but is not immediately supported with the new one.  As an 
added complication I wonder if having hid the expander you can 
still expand and collapse using the + and - keys.

I can't see one.  Is this for a library function or something 
where you are not in control?  If not then the easiest thing to 
do would be to do it as part of the code that actually makes the 
change to the data model.  I know it's imperfect but it's the 
best that I can think of.
