Mon Nov 18 20:42:27 2002  Kristian Rietveld  <kris@gtk.org>

        * gtk/gtktreeview.c (gtk_tree_view_expand_to_path): modify and
        free tmp instead of path ... (patch from #97927).

Mon Nov 18 20:31:20 2002  Kristian Rietveld  <kris@gtk.org>

        * gtk/gtkcellrenderertext.c (gtk_cell_renderer_text_start_editing):
        only _set_text if celltext->text is not NULL. (#97815, reported
        and testcase provided by Vitaly Tishkov).

Mon Nov 18 20:28:28 2002  Kristian Rietveld  <kris@gtk.org>

        * gtk/gtktreeselection.c (gtk_tree_selection_real_modify_range):
        also update the anchor_path, makes behaviour consistent with the
        other selection modification functions. (#96801, reported and
        testcase provided by Vitaly Tishkov).

Mon Nov 18 20:17:56 2002  Kristian Rietveld  <kris@gtk.org>

        Hrm, this fixes up lots of mistakes in my swap/move code ... Some
        of these mistakes where pointed out by Vitaly Tishkov in bugs
        #97403, #97404, #97412, #97618.

        * gtktreestore.[ch]: gtk_tree_store_move is now private, use
        gtk_tree_store_move_{before,after} instead now. Lots of fixes
        (more like a rewrite :) in the _move and _swap functions.

        * gtkliststore.[ch]: likewise.
