It doesn't make sense to keep them separate as GtkSizeRequest requires a
GtkWidget and GtkWidget implements GtkSizeRequest, so you can never have
one without the other.
It also makes the code a lot easier because no casts are required when
calling functions.
Also, the names would translate to gtk_widget_get_width() and people
agreed that this would be a too generic name, so a "preferred" was added
to the names.
So this patch moves the functions:
gtk_size_request_get_request_mode() => gtk_widget_get_request_mode()
gtk_size_request_get_width() => gtk_widget_get_preferred_width()
gtk_size_request_get_height() => gtk_widget_get_preferred_height()
gtk_size_request_get_size() => gtk_widget_get_preferred_size()
gtk_size_request_get_width_for_height() =>
gtk_widget_get_preferred_width_for_height()
gtk_size_request_get_height_for_width() =>
gtk_widget_get_preferred_height_for_width()
... and moves the corresponding vfuncs to the GtkWidgetClass.
The patch also renames the implementations of the vfuncs in widgets to
include the word "preferrred".
* 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/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.
