Another feature to create truly ugly TreeViews!: style properties
for the even/odd colors used for row hinting. (#71595, reported
by Owen Taylor).
* gtk/gtktreeview.c (gtk_tree_view_class_init): add even_row_color
and odd_row_color style properties.
* gtk/gtkstyle.c (get_darkened_gc): support darken_count == 0 case,
(gtk_default_draw_flat_box): rework cell coloring code to support
user-provided even/odd row colors.
Wed Oct 23 01:01:52 2002 Kristian Rietveld <kris@gtk.org>
Cache signal IDs to speed up signal emission. This is a good speedup
because GtkTreeModel emits a big number of signals.
* gtk/gtktreemodel.c (gtk_tree_model_base_init): save IDs returned
by g_signal_new,
(gtk_tree_model_row_changed): use g_signal_emit instead of
g_signal_emit_by_name,
(gtk_tree_model_row_inserted): ditto,
(gtk_tree_model_row_has_child_toggled): ditto,
(gtk_tree_model_row_deleted): ditto,
(gtk_tree_model_rows_reordered): ditto.
Wed Oct 23 00:56:15 2002 Kristian Rietveld <kris@gtk.org>
* gtk/gtktreeselection.c (model_changed): new function,
(gtk_tree_selection_selected_foreach): monitor changes in the model,
bail out if the model has been changed from the foreach func.
(#50263, reported by Havoc Pennington).
* gtk/gtktreeselection.c (_gtk_tree_selection_internal_select_node):
free anchor if applicable (#94868, reported and testcase provided by
Daniel Elstner).
