We used to handle zero height/width specially in the non-double buffered
case due to the weird behaviour of XClearArea in this case. However
this is undocumented, incompatible with what happens on double-buffered
drawing, and just not a good API. So, we drop this behaviour, having
fixed gtkclist.c which used this.
* gtk/gtksettings.c: (settings_install_property_parser): Handle enums too.
* gtk/gtktoolbar.c (gtk_toolbar_class_init): Move the gtk-toolbar-style and
gtk-toolbar-icon-size settings into GtkSettings because we now use it in
GtkToolPalette too.
* gtk/gtktoolpalette.[h|c]: Add gtk_tool_palette_unset_style() and
gtk_tool_palette_unset_icon_size(), and use the toolbar-style and
icon-size from GtkSettings if these are not set via the set functions.
* demos/gtk-demo/toolpalette.c (on_combo_style_changed),
(do_toolpalette): Add and handle a -1 value to mean the desktop "Default"
toolbar style.
* demos/gtk-demo/toolpalette.c (load_special_items): Demonstrate
gtk_tool_item_group_set_label_widget().
* gtk/gtktoolitemgroup.[h|c]: Rename the "item-group-name" property to
"label" because that is what it is. Likewise rename the functions.
Add a "label-widget" propert and get/set_label_widget() functions,
based on the same code/API in GtkExpander.
* gtk/gtktoolitemgroup.[h|c]: Rename the name property to item-group-name
and rename get/set_name() to get/set_item_group_name(), to avoid a clash with
GtkWidget::name.
* gtk/gtktoolpalette.h: GtkToolPaletteClass: Add padding for future use.
* gtk/gtktoolshell.c: Added vfuncs to get/set ellipsize, text-orientation,
text-alignment and size-group plus getter/setters to invoke these vfuncs.
* gtk/gtktoolitem.[h|c]: Added getters and setters to get/set these from the
parent GtkToolShell. This is in the style of the existing "properties".
* gtk/gtktoolbutton.c: Updated to use the extra properties.
* docs/reference/gtk/gtk-sections.txt
* gtk/gtk.symbols: Updated to mention the new functions.
These new "properties" are used by GtkToolPalette.
* gtk/gtktoolpallete.[h|cc]:
* gtk/gtktoolitemgroup.[h|cc]: Added a tool pallete container widget,
with groups of toolbar items that can be shown as a grid of icons
or a list of names.
* gtk/Makefile.am:
* gtk/gtk.h:
* gtk/gtkmarshal.list: Mentioned the new files.
