Added gtk_cell_area_context_get_preferred_height_for_width and
width_for_height & gtk_cell_area_copy_context() to gtk.symbols
and gtk3-sections.txt (also finished up documenting those apis).
gtk_cell_area_foreach_alloc() itterates over an allocated list of cells
and calls a callback with the cell's allocation until the callback returns
TRUE.
- Removed vfunc get_cell_allocation() and implemented
gtk_cell_area_get_cell_allocation() using foreach_alloc()
- Added gtk_cell_area_get_cell_at_position() using foreach_alloc()
- Removed GtkCellAreaBox ->event() implementation and implemented
mouse "click" cell activation in GtkCellArea class directly using
gtk_cell_area_get_cell_at_position().
gtk_widget_override_*() deprecates gtk_widget_modify_*(). There are
only functions to modify fg/bg/font/symbolic color, If anything more
fancy/complex is needed. There is the possibility of adding a
GtkStyleProvider yourself.
gtk_widget_(set|unset|get)_state_flags() has been added, using GtkStateFlags
to represent the widget state. GtkStateType API has been implemented on top
of the new one.
It actually messed up with the state being actually set, and having a
transition animation running for it. Now this dichotomy is removed, and
gtk_style_context_state_is_running() only checks whether an animation is
running, leaving state checking to flags & GTK_STATE_FLAG_*.
Based on a patch by Matthias, add an "active-id" property for
GtkComboBox and add some convenience API for GtkComboBoxText.
Also, add a test case to gtk-demo.
It is really bad code, mostly unused and no one stepped up to fix it.
Note that Gtk developers do not object to a ruler widget in priciple,
just to the current implementation. If someone wants to propose a sane
version, please don't hesitate.

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.
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.
Use input-only windows for capturing input, and just draw onto
the parent window. This allows themes to make entries with rounded
corners. Patch by Boram Park.

GtkComboBox now sports a construct-only "has-entry" property which
decides if it uses a GtkEntry to allow additional user input. Also
it has a new "entry-text-column" to fetch strings for the entry
from the model.
This patch deprecates the GtkComboBoxEntry and updates the rest of GTK+
to use the new semantics on GtkComboBox instead.
GtkComboBoxEntry will be removed altogether before GTK+ 3, in a
later commit.
We remove the resize grip from GtkStatusbar, but keep the code
that makes the content avoid the grip, and adapt it to GtkWindow
grips.
The gtk_status_bar_set/get_has_resize_grip() functions and related
properties are removed.
Allow any window to display a resize grip, in the south-east or
south-west corner, depending on text direction. This is implemented
as a shaped window that gets overlayed on top of whatever content
is there. We add api that allows widgets to avoid the resize grip,
if desired.
The ::has-resize-grip property controls if a window may display
a resize grip. It will only be displayed if the window is resizable
and not maximized.
The size and visual appearance of the resize grip is under theme
control, using the resize-grip-width/height style properties and
the paint_resize_grip style function.
It turns out that the previous handling of just providing a way to set
visuals just on toplevels was not sufficient. In particular it
complicated the various implementations of the tray icon specification.
This patch reintroduces gtk_widget_set_visual() which behaves very
similar to GTK2's gtk_widget_set_colormap().
A future commit will remove the gtk_window_set_visual() function.
The function reverses the transform that GTK does before emitting a draw
event. So we can use it in "old" widgets to revert the coordinate system
properly.
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".
The functions are gtk_widget_get_allocated_width() and
gtk_widget_get_allocated_height().
They are currently identical to using width/height of
gtk_widget_get_allocation(), but are introduced for ease of use (no need
to use a custom struct) and to free people from having to think about
allocation.x and allocation.y (which is where the origin of the cairo
context in GtkWidget::draw is located).
This removes:
gtk_widget_set_default_colormap()
gtk_widget_get_default_colormap()
gtk_widget_get_default_visual()
Colormaps are gone, and the default visual is the system visual of the
default screen.
Add gtk_window_set_visual() and a "visual" property. This allows
changing the window visual to the rgba one and other awesome things
(like implementing the trayicon spec).
Replace gtk_widget_shape_combine_region() with
gtk_widget_shape_combine_mask() and
gtk_widget_input_shape_combine_region() with
gtk_widget_input_shape_combine_mask().
As GdkBitmap is going away, and the region equivalents already exist,
this seems like pretty much the default step to take.
Includes code to fix up the users.
Dealing with bare pointers is problematic for language bindings,
using interned strings is much more straightforward and more than
good enough for what is needed here.
