Wed Oct 25 20:40:25 2000 Jonathan Blandford <jrb@redhat.com> * gtk/gtktreemodel.h: Got rid of GtkTreeNode, and changed it to GtkTreeIter. Added iterators everywhere. * gtk/gtktreeviewcolumn.c: Changed to use the iterators. * gtk/gtktreeviewselection.c: Changed to use the iterators. * gtk/gtktreestore.c: Changed to use the iterators. * gtk/gtkliststore.c: Commented out the code. Will convert to iterators tomorrow. * gtk/gtkmodelsimple.c: Commented out the code. Will convert to iterators tomorrow. * gtk/treestoretest.c: Changed to use iterators. * demos/testgtk/main.c: Moved to use the new iterator system.
