The forall() loop was buggy as it was skipping items in the list when
the current item gets removed from the groups array as a result of
calling the callback (causing memory leaks).
This patch adds the GtkScrollablePolicy type property to GtkScrollable
and implements it in all subclasses. GtkScrolledWindow observes this
property to make a good guess about when to show/hide scrollbars for
height-for-width content.
Most scrollable children do not do height-for-width *yet* but
most certainly will (toolpalette, treeview, iconview, textview
widgets all TODO), for scrollable widgets that do have a minimum
and natural size, it's important for them to observe the state
of this property in order to properly drive the scroll adjustments
according to the desired GtkScrollablePolicy. This patch makes
GtkViewport do this.
Patch also adds tests/testscrolledwindow.c to display the effects
of this property.
It is just too annoying to have to implement these properties in
every scrollable. Instead, we now have ::min-content-height/width
in GtkScrolledWindow.
We also add GtkScrollablePolicy to determine how to size the
scrollable content.
Create a new adjustment if there was *no* adjustment passed in, not
the other way around. Also remove unused function
gtk_tool_palette_set_adjustment().
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.
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".
It seems with latest GSEAL work for widget->window access a
call to gtk_widget_set_window() was missed (added the window
assignment and now the palette shows up in Glade again).
* 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.
GtkIconSize is an extensible enumeration (via
gtk_icon_size_register()), so methods that claim to take/return a
GtkIconSize need to actually use "int" to work correctly with bindings
that are strict about enum values.

* 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/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.
