This patch changes all uses of GDK_DEPRECATED(_FOR) in gtk headers
by the versioned variants, GDK_DEPRECATED_IN_3_x(_FOR). At the same
time, we add GDK_AVAILABLE_IN_3_x annotations for all API additions
in 3.2 and 3.4.
The GtkScrollable interface provides "hadjustment" and "vadjustment"
properties that are used by GtkScrolledWindow. It replaces
the ::set_scroll_adjustment signal. The scrollable interface
also has ::min-display-width/height properties that can be
used to control the minimally visible part inside a scrolled window.
* gtk/gtktoolpalette.[h|cc]: gtk_tool_palette_get_drop_group():
Change the return type from GtkWidget* to GtkToolItemGroup*,
for consistency with other parts of GTK+, such as GtkToolbar.
* 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.
* 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/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.
