gtk_window_get/set_attached_to() is a new API that allows for windows to
be attached to a GtkWidget.
The attachment is a logical binding between the toplevel window and the
widget that generated it; this kind of information is currently used to
propagate style information from the widget to the window, but is also
useful e.g. for accessibility.
https://bugzilla.gnome.org/show_bug.cgi?id=666103
'window-unfocused' is too long and mentions "focus" which is historically
loaded with the meaning "input focus".
'backdrop' isn't generally used in GUI speak and still conveys the state the
widgets in an unfocused or background toplevel window are in.
Move internal accel map API there and update all users.
Also, add an internal function to create an accel path for
an action and parameter, and use it in gtkapplication.c and
gtkmodelmenuitem.c instead of duplicating that code.
Even if we can't change our sensitivity because the parent is insensitive we
should still flip the sensitive flag. Otherwise, with and insensitive parent,
child.set_sensitive(True)
...
parent.set_sensitive(True)
would result in child still being insensitive.
https://bugzilla.gnome.org/show_bug.cgi?id=666392
In many cases we used to set focus_child to NULL all the way up
to the top and then to the right value, even if there was
a common ancestor, meaning these see a temporary NULL value for
focus_child. Only when the new focus widgets direct parent was
in the previous ancestor list did we stop early.
This fixes that by always stopping propagation when reaching
the common ancestor.
This function returns the accessible if it already exists. This way we
can call functions on the accessible from the widget itself instead of
having to rely on signals.
This is kind of a hack to get rid of infinite loops that occur when
child accessibles try to set their parent upon creation but the parent
accessible creates its children in the initialize vfunc. Because in that
case, the parent will not have an accessible set when the child tries to
access it, because it is still initializing itself. Which will cause a
new accessible to be created.

Add enum GdkModifierIntent which identifies use cases for modifier masks
and GdkKeyMap::get_modifier_mask(). Add a default implementation which returns
what is currently hardcoded all over GTK+, and an implementation in the
quartz backend. Also add gtk_widget_get_modifier_mask() which simplifies
things by doing widget->display->keymap->get_modifier_mask().
This commit introduces a new setting, gtk-visible-focus, backed
by the Gtk/VisibleFocus X setting. Its three values control how
focus rectangles are displayed.
'always' is equivalent to the traditional GTK+ behaviour of always
rendering focus rectangles.
'never' does what it says, and is intended for keyboardless
situations, e.g. tablets.
'automatic' hides focus rectangles initially, until the user
interacts with the keyboard, at which point focus rectangles
become visible.
https://bugzilla.gnome.org/show_bug.cgi?id=649567
We want the role to be kept in the accessible object. Using
gtk_widget_class_set_accessible_role() is only meant as a quick
workaround to requiring subclassing of the accessibles in the quite
common case where a subclass does not change the accessible
implementation at all and only has a different role.
The function is supposed to bypass the ATK registry. For 2 reasons:
1) We get rid of a lot of boilerplate madness.
2) The registry allows creating multiple accessibles per widget and we
don't.
The old code for registries is still there.
Doing it unconditionally is not useful when the subclasses actually
using them can only ever do it in the style_updated signal. So do it in
the style_updated handler instead.
Include the child widget path in the returned path now. This allows
customizing the path of the current widgets - like adding flags to child
widgets (and maybe siblings in the future).
This is a variant of gtk_widget_child_notify() that takes an
explicit container, instead of relying on widget->parent to
be the correct container to use.
Also print the parent widget. As the parent's size_allocate
implementation is usually the culprit for this warning happening, it
makes sense to print it.
Mnemonics for characters that go beyond the baseline (q, y, g) were not
being shown, because they are drawn outside of the label's allocated
size.
This patch just disables the clip-to-size for labels, so that the label
can draw outsize of its allocation. In most cases, that works around
this bug.
https://bugzilla.gnome.org/show_bug.cgi?id=648570
Instead rely on state_flags & GTK_STATE_FLAG_INSENSITIVE to tell us if a
widget is sensitive.
This has the huge benefit that the way the widget is actually rendered
corresponds to the return value of gtk_widget_is_sensitive().
As a side effect, we do not ever allow unsetting the
GTK_STATE_FLAG_INSENSITIVE for a widget the is set to not be sensitive
(via gtk_widget_set_sensitive()). This way we stop propagation of making
stuff sensitive at insensitive widgets.

This commit makes GTK_ALIGN_START/_END pay attention to
the text direction when used in horizontal context.
This is how similar parameters in GtkMisc and GtkAlignment work,
and is generally expected of GTK+ positioning parameters. And this
is new GTK+ 3 api, so it is basically still unused at this point.
If explicit right/left turn out to be needed at some point, we
can expand the enumeration with new values.
This ensures that widgets that aren't ported and rely on the style-set
signal being emitted work as well as before. They should not rely on
style-set being emitted however.
Note that this function is a no-op if the initial style has been set
already and is very cheap if it has not been set yet. It only becomes
relevant if the resulting style actually gets used.
https://bugzilla.gnome.org/show_bug.cgi?id=639584
The intention of this patch is to make the code clearer, shorter and
most of all to avoid recreating the widget path and setting it path
twice on the style context when the style context was recreated.
This patch optimizes window resizes by assuming that if a widget
has the same height at a width of 50 as with a width of 150, the
height for width 100 will also be the same.
The patch also further optimizes the cache allocator, now there
are 2 pointer arrays of up to a maximum of 5 requests, the arrays
will only be allocated if a request is ever made in that orientation
and the array will be sparse until each request is made (i.e. if a
label can only wrap to 3 lines, there will only be 3 out of a
possible 5 SizeRequest structures allocated to cache it).
This patch makes contextual height-for-width request caching
optional (the contextual cache is not allocated for widgets that
report GTK_SIZE_REQUEST_CONSTANT_SIZE).
The constant size request mode defines a request mode where
height-for-width geometry is unneeded, thus optimizing GTK+
by reducing the overall amount of requests that need to be
performed and cached while resizing an interface.
Fixes Bug 639584 - initial emission of GtkWidget:style-set is
not happening.
GtkWidget was filtering out ::style-updated (and ::style-set)
emissions until the widget was realized in order to avoid often
useless updates during widget construction and placing.
This is now done instead until the widget has a parent/screen,
which ensures the initial emission happen prior to the first
size negociation, while still filtering out all early emissions
during construction.
Writing onto the passed-in GtkStateData could cause changes that would
propagate to siblings, as the data was not reset again.
By copying the data structure, this is avoided and the proper values are
passed to sibling widgets.
GtkWidget now parses custom attributes like
<style>
<class name="dark-label"/>
<class name="big-heading"/>
</style>
to add style classes to widgets.
https://bugzilla.gnome.org/show_bug.cgi?id=643347
Sensitivity changes were not properly propagated down the
hierarchy. There were two issues here:
a) correctly identifying when a state change request affects
sensitivity
b) not filtering out sensitivity in gtk_widget_propagate_state(),
since gtk_widget_set_sensitivity() uses that to do its work
https://bugzilla.gnome.org/show_bug.cgi?id=641431
Optimized GtkSizeGroup code that is invoked for every queued resize
and every request that is not previously cached by trading qdata on
widgets for 3 extra bitfields on the GtkWidgetPrivate structure.
It is used to get the default providers, without them
the style context can't do much. A check for NULL screen
is done before any sensitive call to
gtk_style_context_set_screen(), in the hope that any widget
will open the display before doing anything related to
styling. Fixes bug #641429, reported by Bastien Nocera.
This management is better done per-widget rather than per-screen,
as windows being destroyed won't trigger a leave notify for the
devices on top of it, and this information is too transitive
to keep weak refs and such.
This fixes the critical warning seen in gtk/tests/testing.
Instead of checking if klass->get_request_mode is != NULL from
the gtk_widget_get_request_mode() api, this allows classes to
trust that there is a default implementation and chain up (specifically
added this for gtkmm wrapper objects).
GtkStateType was generally used as an index in GtkStyle color arrays, so
bigger values will cause invalid memory accesses in widgets that are still
doing that. this was seen in focused GtkIconViews for example
together with commit 8903615a34, this finally fixes bug #640282.
Insensitivity is handled separatedly in _gtk_widget_update_state_flags(),
but the insensitive flag is mistakenly unset afterwards if clear is TRUE
in gtk_widget_set_state_flags().
There is only one widget supposed to have the focused flag at a given time,
so avoid propagating the state down the hierarchy, the focused flag is now
also set in _gtk_widget_set_has_focus().
This function is a more convenient variant than
gtk_widget_set_device_events(), as it will
1) perform changes down a widget hierarchy, to
all windows.
1) use the same event mask than gdk_window_get_events()
This function takes a region ID and cancels all animations
on or beneath that region (as in push/pop_animatable_region).
First user of this is GtkWidget itself, so unmapped widgets
have looping animations cancelled. Fixes bug #638119, reported
by Jesse van den Kieboom.
Now GtkWindow takes some measures when setting toplevelness:
- When a window becomes toplevel after being embedded it saves
the visibility state and reshow's itself so that the window
re-realizes and presents itself again automatically
- When emitting hierarchy-changed, synthetically mark the toplevel
as not anchored, this allows the hierarchy changed propagation to
recurse properly.
GtkWidget also takes care to unset the parent window *after* unparenting
the widget and after emitting the heirarhcy changed that leaves a NULL
toplevel.
That means there are now 2 cycles of "hierarchy-changed" when removing
an embedded toplevel from a parent, first one that makes the new toplevel
a NULL one (since the toplevel flag is not yet restored), the second cycle
makes the removed window toplevel again when setting the parent window
to NULL.
GtkFileChooserDefault watches the toplevel and montitors "set-focus"
signal on it... however the connection needs to be remade when the
GtkFileChooserDialog is in an embedded toplevel.
Measure's taken: GtkWindow propagates hierarchy changes when
_gtk_window_set_is_toplevel() is called, gtk_widget_unparent()
unsets the widget's parent window earlier in the function so that
the possible hierarchy change is still able to properly access the hierarchy.
GtkFileChooserDefault checks if the "new" toplevel is indeed
gtk_widget_is_toplevel() but not the old one, GtkRange has been
updated to use gtk_widget_is_toplevel() inside it's hierarhcy_changed
vfunc, other classes already do this properly.
This patch makes gtk_widget_set_parent_window() undo the toplevelness
of a GtkWindow, GtkWindow then realizes itself as a normal child widget
and behaves like a normal GtkBin by checking gtk_widget_is_toplevel() in
several places (show/hide/map/unmap/draw/size_allocate/check_resize/configure_event).
For normal toplevels, visible is tightly bound to mapped, but for
something like a toplevel that exists within a Clutter stage we
may want to make mapping dependenton external factors, so we shouldn't
actually checked that !mapped toplevels are !visible.

Previously, for performance reasons we would sometimes
skip invoking the unmap signal (and associated vfunc)
in favor of simply unrealizing. However, widgets then
had no way to clean stuff up when they were hidden
(but still inside a parent which was shown).
This patch also removes _gtk_tooltip_hide() which
was done in both unmap and unrealize in gtkwidget.c,
now can only be in unmap.
There are probably lots of things cleaned up in
unrealize that would now be better to move to unmap.
https://bugzilla.gnome.org/show_bug.cgi?id=629923
Requires fixes to GtkContainer and GtkWindow to unmap their
children, rather than just withdrawing or hiding the container
window.
Requires fix to GtkHandleBox to chain up to GtkContainer unmap.
Historically we avoided these unmaps for efficiency reasons,
but these days it's a bigger problem that there's no way
for child widgets to know that one of their ancestors has
become unmapped.
These checks are a bit expensive so require --enable-debug=yes.
gtk_widget_verify_invariants() checks invariants mentioned
in docs/widget_system.txt in particular, and can verify
others in the future.
Some of the invariants in docs/widget_system.txt don't
in fact hold right now, so those are #if 0'd in this
patch pending someone fixing either the docs or the code.
Most code in gtkrc.c has been turned into a no-op, but that one
reverting in public API (gtk_rc_scanner_new() and such). GtStyle
is also more shallow, now fully relies in the backing
GtkStyleContext and all connection to gtkrc.c has been removed.
GtkBinding has been also affected, there is no replacement yet
for custom keybindings in style files, so that piece of code that
hooked into gtkrc has been replaced by a FIXME so in the future
it may be added back.
In the process of removing all sealed members from headers.
At the same time, add a gtkwindowprivate.h header and move
all internal functions from gtkwindow.h there.
The old functions to get core pointer and devices list are gone as
well. This slice is entirely replaced internally by multidevice
handling and may just go.
This allows us to add a check before executing
->get_preferred_height_for_width() to ensure we always
request for at least the minimum required size (and lets
us remove the warning in gtkcontainer.c telling implementors
to do this check manually from thier container implementations).
This object backs up gtk_widget_override_* operations. This object
is not meant to be public because any intention to modify widgets'
style in a themeable way should involve using regions/classes, so
they're modifiable through CSS. As such, the API is really
short-scoped.
Things like font settings depend on the screen, and widgets
like GtkTextView trigger queries on widgets without screen
when the parent window is being destroyed.
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.
This is now used throughout in order to have the full path for a given widget,
including intermediate named regions, the default implementation just returns
the GtkContainer's path copy, no intermediate regions between.
Some unparented widgets like to ask style details, so now the style is
constructed regardless of the parent being present or not, and then
reconstructed if the parent changes.
There will be one GtkStyleContext per widget, at the moment its
lifetime is tied to the widget's, but it could be narrowed down
to GTK_WIDGET_REALIZED.
Now gtk_widget_size_allocate() unsets the resize_needed flags
before returning, essentially this means that any widget that
has a queued resize and is allocated before resize time, including
queued resizes from inside a size_allocate() method will be
cancelled.
alignment/margin vfuncs adjust_size_request/allocation
Now get_height_for_width() will internally update the for_width
before passing it to the real height_for_width() vfunc, allowing
margins and extra space for alignments to be stripped, thus requesting
sufficient height for greater than natural widths (and also accounting
for margins properly). Test case adjusted in testadjustsize to ensure
proper behavior.
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.
- add slots for damage-event, move-focus and keynav-failed
- reorder signals a bit so related stuff is grouped together
- some indentation fixes in the GtkWidgetClass
- remove the move-focus compat hack from GtkTextView
- turn the move-focus compat hack in GtkWindow into properly
implementing GtkWidget::move-focus()
The gtkprivate.h header contains GtkWidget-specific private symbols that
are not useful except in a handful of cases. Basically everything
includes gtkprivate.h for the GTK_PARAM_* macros.
https://bugzilla.gnome.org/show_bug.cgi?id=632539
This path would only do anything where widget->window was not located at
widget->allocation.x/y but at a different position. This should never
happen in the real world. But if it does, GTK3 will break for you.
Better fix your widget.
GtkWidget now has flags for horizontal and vertical expand, and
a compute_expand() method. compute_expand() is used by containers
to set a default expand flag. (If a widget has expand set explicitly,
it always overrides the results of compute_expand.)
GtkContainer has a default implementation of compute_expand which
simply walks over all child widgets and sets expand=TRUE
if any child is expanding.
The overall effect is that you only have to set expand on
leaf nodes in the widget tree, while previously you had to
set expand all the way up the tree as you packed every
container. Also, now containers need not have their own child
properties for expand.
For old containers which do have "expand" child properties,
they should override compute_expand and include the child
properties in whether the container is expand=TRUE.
Also, the old container should use
"child_prop_expand || gtk_widget_compute_expand()" everywhere
it previously used simply "child_prop_expand"
https://bugzilla.gnome.org/show_bug.cgi?id=628902
The geometry widget feature of gtk_window_set_geometry_hints() has
never really worked right because the calculation that GTK+ did to
compute the base size of the window only worked when the geometry
widget had a larger minimum size than anything else in the window.
Setup:
* Move the GtkSizeGroup private functions to a new private header
gtksizegroup-private.h
* Add the possibilty to pass flags to _gtk_size_group_queue_resize(),
with the flag GTK_QUEUE_RESIZE_INVALIDATE_ONLY to suppress adding
the widget's toplevel to the resize queue.
* _gtk_container_resize_invalidate() is added to implement that feature
* _gtk_widget_override_size_request()/_gtk_widget_restore_size_request()
allow temporarily forcing a large minimum size on the geometry
widget without creating resize loops.
GtkWindow:
* Compute the extra width/height around the geometry widget
correctly; print a warning if the computation fails.
* Always make the minimum size at least the natural minimum
size of the toplevel; GTK+ now fails badly with underallocation.
* Always set the base size hint; we were failing to set it
properly when the specified minimum size was overriden, but
it's harmless to always set it.
Tests:
* New test 'testgeometry' that replaces the 'gridded geometry' test
from testgtk. The new test is roughly similar but creates a bunch
of windows showing different possibilities.
* The testgtk test is removed. No need to have both.
https://bugzilla.gnome.org/show_bug.cgi?id=68668
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.
When fitting a widget into its allocation, the second dimension
is always dependent on the first, so gtk_widget_get_preferred_size()
cannot be used directly (because we want the natural height for
the allocated width, not the natural height for the natural width,
which is generally a smaller height than the height-for-minimum-width
or height-for-allocated-width).
Added test to testadjustsize to ensure proper behaviour.
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".
Previously, we tried to move the context's origin to the widget's top
left location, no matter what window the paint was happening on. Now we
only do that for child windows of the widget's window and leave the
context untouched for windows that the widget has created outside its
own hierarchy. In those casses, we also don't clip the context to
the widget's allocation.
Includes fixes to GtkHandlebox for this effect and fixes all known
issues with it.
These semantics assume that gtk_widget_draw() should only draw the parts
of a widget that are inside child windows and not draw stuff that is
located in completely different GdkWindows. In the handlebox case, it
means that it should only draw the handle when it is attached, but not
when it isn't. We'll likely need a special draw function for the
detached handlebox if we want to draw it.
I've seen (and written) quite some widgets (and theme engines) that use
cairo_paint() to draw the background. So avoiding overdraw makes sense.
Also move all that setup into a _gtk_widget_draw_internal() function
that will be used by all functions that can be used by other functions
that draw widgets.
For now, the draw signal is emitted by default from the expose event, so
widgets can chose to either implement the expose event or the draw
function.
This is for the transitional period from expose event to draw signal.
Note that for now subclasses can only implement the draw function when
none of their parents implemented the expose event.
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).
We now return the visual of the topmost widget in widget's stack that
has a window. If no such widget exists, but a GtkWindow is a parent, we
return its visual (note: GtkWindow Will gain support for setting visuals
soon). If a window doesn't exist, we return the system visual of the
default screen.
This change has multiple reasons:
- Colormaps are gone
Now visuals are the most important resource for creating GDK windows.
- Allow widgets to change visuals for themselves and their children
By walking the hierarchy, we ensure that child windows have the same
visual as their parents by default. But widgets can still select a
different visual in their realize handler when creating the GDK
window.
- Have a replacement for gtk_widget_set_colormap()
That function is going to die with colormaps, so a replacement was
needed. That replacement is going to be gdk_window_set_visual().
- Make a future transition to no-window GTK easy
Should we ever attempt a change to make all GTK widgets no-window, a
gtk_widget_set_visual() would be silly, as only widgets with windows
can have their own visuals. So only toplevels will gain the ability to
change it.
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.
h-align = START,END,CENTER,FILL
v-align = START,END,CENTER,FILL
margin-left,right,top,bottom
margin
These should obsolete all such similar properties on
layout containers, GtkMisc, GtkAlignment, GtkContainer::border-width
Margin is outside the size request.
If margin were not outside the set_size_request() it would not work the
same way as container-supplied (child property) padding.
Conceptually set_size_request() forces the value from the subclass
(the original unadjusted request) and then we go on to adjust
the request further by adding the margin.
Use these new methods to handle set_size_request (aka aux_info)
inside gtkwidget.c, instead of having external code mess with it.
The virtual functions can be used for other purposes in the
future. For example, GtkContainer::border_width could be
automatically implemented for all container subclasses.
Did not update uses in other files because the plan is to
get rid of those other uses anyhow. So don't want to make
this function available in the header.
This is better than peeking aux info then testing != NULL
in several ways:
- it returns const aux info so if we don't create we can't write
- it ensures that the default we assume if aux_info is NULL is
the same as the default we set if we've created the aux info
- it avoids typing in != NULL checks
In GtkBin and GtkWidget we tried to provide handy defaults that
call get_width if there's no get_width_for_height and
get_height for get_height_for_width.
However, they used the wrapper API on GtkSizeRequest instead of
chaining directly to the other method implementation.
This could result in all kinds of surprising behavior, for example,
get_width_for_height() would now already include the effects of set_size_request().
If nothing else it's inefficient. But it's just conceptually wrong,
because to chain to another implementation, we should call the other
implementation, not call a wrapper around the other implementation
(when we're already inside a previous invocation of the wrapper,
i.e. compute_size_for_orientation() ends up reinvoking itself
in the same orientation on the same object which it pretty
likely isn't intending to do)
https://bugzilla.gnome.org/show_bug.cgi?id=628829
gtk_widget_set_window() does not add a reference to the
owned window... this is an exception to most gtk_foo_set_bar()
functions where as it acts as if it were named gtk_widget_take_window().
Adding note to the docs to avoid people giving the window to the
widget and naturally proceeding to unref the window.
Now that we have a private data installed directly on
the GtkWidget instance it makes no sense to cache the size
requests on widget qdata. This change will generally make
GTK+ memory less fragmented as well as significantly speed
up the size request process.
The keysyms create a lot of potential namespace conflicts for
C, and are especially problematic for introspection, where we take
constants into the namespace, so GDK_Display conflicts with GdkDisplay.
For C application compatiblity, add gdkkeysyms-compat.h which uses
the old names.
Just one user in GTK+ continues to use gdkkeysyms-compat.h, which is
the gtkimcontextsimple.c, since porting that requires porting more
custom Perl code.
Preferrably should be made just into a local variable for libgtk like
_gdk_debug_flags for libgdk. But for now used by
gtk/tests/textbuffer.c and modules/printbackends/cups/gtkprintbackendcups.c.
Since we have a new mechanism for requesting sizes: GtkSizeRequestIface;
it makes no sense to maintain this cache on the GtkWidget structure...
removing the requisition cache however does not break the old "size-request"
signal which is there for backwards compatability reasons.
In any case widget->requisition should not have been accessed,
gtk_widget_get_child_requisition() would have been the correct way
to consult the cache.
This commit also deprecates the newly added gtk_widget_get_requisition()
API and makes it fallback on gtk_size_request_get_size().
These members of GtkWidgetAuxData can no longer be set after
the removal of deprecated gtk_widget_set_uposition(), now removed
these members completely and removed the access to them from
gtk_widget_size_allocate().
Allow windows to be dragged by clicking on empty areas in menubars
and toolbars. This is under theme control, via the GtkWidget::window-dragging
style property. The idea is that it makes sense to turn this on if a
theme makes the window frame and the menubar/toolbar appear visually
contiguous.
The main patch was written by Cody Russell, with a contribution by
Ayan George. See bug 611313.
Includes fixing all callers to use the cairo region API instead. This is
usually just replacing the function names, the only difference is
gdk_region_get_rectangles() being replaced by
cairo_region_num_rectangles() and cairo_region_get_rectangle() which
required a bit more work.

This commit makes a few massive changes to the extended layout
code:
a.) gtkextendedlayout.c --> gtksizerequest.c
b.) _is_height_for_width --> get_request_mode()
c.) get_desired_size(), get_desired_width(), get_desired_height() -->
get_size(), get_width(), get_height()
This is the first partial commit and only effects portions
of the tree that have already been merged in master (in order to
easily cherry pick this commit).

Currently the only users of the GTK_HAS_FOCUS flag are setting it
before sending a focus change event. This is normally needed by
GtkWindow, but there are widgets that require controlling the focus
of widgets that are semantically their children even though they are
parented to another top-level. Case in point: the quick search entry
for GtkTreeView.
Over the years people have been hacking the focus change out of
gtkwindow.c and gtktreeview.c, thus leaking the direct access of the
GTK_HAS_FOCUS flag.
The simplest way to avoid that is to add a function that sends the
focus change event and controls the setting of the flag, thus removing
the need for external widgets to do the same.

Removed _gtk_size_group_compute_requisition and
_gtk_size_group_get_child_requisition in favor of
_gtk_size_group_bump_requisition() which does an orientation
contextual computation of the size group and returns the
collective value in one pass.
This commit changes gtk_extended_layout_get_desired_size() for
per dimension variants. Furthermore this commit reverts the actions
done in size-groups for now as it needs a different approach.
The natural width/height parameters added to aux_info have been changed
for a per width cache for heights and a per height cache for widths.
gtk-demo is still working, currently sizegroups are not taken
into account as mentioned above - size groups need to be alerted both
when the widths and heights are updated independantly and then that
information needs to repropagate also to other extended layout implementors.
Ever since size groups gtk_widget_size_request() can be used in place
of gtk_widget_get_child_requisition(), deprecating both now in favor
of gtk_extended_layout_get_desired_size().
As it is not allowed to called gtk_extended_layout_get_desired_size()
on a GtkWidget directly; gtk_widget_get_desired_size() was really an
ambiguous api. This patch removes the added GtkWidget api, calls
the appropriate sizegroup code which in turn envokes the interface
vtable, this patch also accordingly makes GtkWidget a prerequisite
of GtkExtendedLayout (the api doesnt work for cell renderers anyway,
patch comming...).
When doing size-requests and get_natural_size() calls, use 0 as
the base value instead of -1, because size_request code assumes
that widget->requesition is initialized at 0.
Because "size-request" signal can be handled by signal connections as well
as by third party derived classes it is necessary to always fire the
"size-request" signal for every recalculation of the widget requisition,
now gtksizegroup.c:do_size_request() fires the signal first and allows it
to overflow the minimum/natural sizes returned by extended layout
implementations.
GtkWidget->get_natural_size() is now left assigning default -1 values to
ensure they both get overridden by the size-request handling.
This commit was created using a script that searched for all docstrings
containing a parameter and the string 'or %NULL'.

There are no side effect of setting these flags and we don't fire g_object
notifies also. Thus set/unset right away without costly check of current state.
Deprecate widget flag macros GTK_WIDGET_STATE, GTK_WIDGET_SAVED_STATE,
GTK_WIDGET_FLAGS, GTK_WIDGET_TOPLEVEL, GTK_WIDGET_NO_WINDOW and
GTK_WIDGET_COMPOSITE_CHILD.
Also deprecate the type macros GTK_WIDGET_TYPE, GTK_OBJECT_TYPE_NAME and
GTK_OBJECT_TYPE which have become redundant.
Instances of GTK_WIDGET_TOPLEVEL are replaced with gtk_widget_is_toplevel,
GTK_WIDGET_TYPE is replaced with G_OBJECT_TYPE, GTK_WIDGET_COMPOSITE_CHILD
is replaced with use of the "composite-child" property and uses of
GTK_WIDGET_NO_WINDOW are adjusted to use gtk_widget_get_has_window.
Uses of GTK_WIDGET_SAVED_STATE and GTK_WIDGET_FLAGS inside GtkWidget are
changed to direct flag usage.
Documentation is updated to refer to gtk_widget_set_has_window and
gtk_widget_get_has_window.
Gail and tests are updated as well.

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.

The Gtk-custom.c file in gir-repository contained a number of
introspection annotations. Merge those into the GTK source files.
Some documentation was moved from the tmpl/ files to accomodate
the addition of annotations.
