I had the same problem and solved it in the following way:
For each node that needs expander but have no real data in its brach I
create a fake row that contains no data. When this row is not expanded
user doesn't see this anyway. When it needs to be expanded I quickly
remove this fake row and add real data and then expand the tree. I had
some problems with Gtk+ that crashed when I messed with model's data in
some signal handlers, but finally I've managed to do it. Unfortunatelly
I'm using Gtkmm so I don't think my code would be an usable example for

struct Sig {
  string name("     J a r e k   D u k a t     ");
  string mail(" madmaxer (at) poczta (dot) fm ");
