Nevermind the visual bug (where the subtree appeared even though the "UNIX - /" item was collapsed)--I did a gtk_widget_show(fs_tree) (the subtree), which I see from reading the Tutorial that I shouldn't have. However, the question of how to set collapsed/expand setting using gtk_* calls still remains. -- To unsubscribe: mail -s unsubscribe [EMAIL PROTECTED] < /dev/null
