Re: Bug in GtkCTree (gtk+ 1.2.10) or am I just misunderstanding the API?

Thanks!

But my program uses no pixmaps and gtk_ctree_node_get_text() still returns bad
data for column 0, not columns 1-n.  However, gtk_ctree_node_get_pixtext()
works.  I'm suspicious that gtk_ctree_node_get_text() was never debugged
because everybody uses pixmaps in column 0.

I'll see if I can produce a test case using no pixmaps.  That would require a
little bit more work with testgtk.c, but it would be a royal pain with my
program.

By the way, is the GtkCTree widget documented anywhere?  The tutorial is "under
construction" and both New Riders' books I have don't have any example code.
