_gtk_accessibility_init() only gets called if the default
display changes, but in case gdk_init() is called before gtk_init()
the default display is already set and no property notification occurs.
This can happen quite easily in pygobject where
"from gi.repository import Gdk, Gtk"
will call gdk_init() followed by gtk_init() in the Python overrides.
This fixes it by checking for a default display in all cases.
Defer a11y initialization until we have a display. A11y initialization
causes widget classes to be initalized, which in turn needs some
backend-specific information about modifier masks that can't be
obtained before we have a display.

This is implicitly done for us in the case of grabs on windows from other
groups, but we must perform this check explicitly for grabs with
owner_events=True on windows from the same group, in that case the window
would handle the events as if there was no grab.
https://bugzilla.gnome.org/show_bug.cgi?id=752327
Popovers may be spawn when there's GTK+ grabs somewhere else (eg.
text selection popover/handles in an entry in a modal popover). When
this happens, events go to the grab widget (in this case the modal
popover) and are effectively ignored by the event widget, even though
it's can be conceptually a child of the grab widget.
To get away with this, tweak a bit gtk_main_do_event(), so events going
to popovers that are related to grab_widget or a child of it are received,
as it would happen with regular children of grab_widget.

The changes in commit 13e22e2030 made
_gtk_window_check_handle_wm_event() indirectly depend on
gtk_get_current_event_time() which relies on the current event being
available on the current_events stack.
Since the current event is only pushed on the stack afterwards we get
an invalid timestamp which breaks ewmh window moving.
This fixes the issue by pushing the current event before we start
relying on it being there in gtk_main_do_event() and, as a byproduct,
also fixes a potential memory leak when we have a rewritten event and
return early due to _gtk_window_check_handle_wm_event() being TRUE.

The gesture is hooked to the capture phase, so it works for buttons in
header bars and whatnot. In order to be friendly to the widget it is
capturing events from, an ugly hack is in place to avoid capturing
events when the target widget has a gesture that would consume motion
events.
The current way of exposing GDK API that should be considered internal
to GTK+ is to append a 'libgtk_only' suffix to the function name; this
is not really safe.
GLib has been using a slightly different approach: a private table of
function pointers, and a macro that allows accessing the desired symbol
inside that vtable.
We can copy the approach, and deprecate the 'libgtk_only' symbols in
lieu of outright removal.

Introduce a new debug category "actions" and write some messages from
GtkActionHelper about if we can find the actions or not.
We will probably soon want to add some similar messages to
GtkMenuTrackerItem.

Prevent a segfault in unknown circumstances, and break the ignore
deprecations wrapper out from the if statement so that we don't
cover too much ground by accident.
This reverts commit b875572f2a.
Apps like Abiword, gnumeric and gnome-chess, and toolkits like
ClutterGTK were all using this for various purposes, and this made them
break. Bring back this feature for now.
It still won't work under Wayland.
gtk_widget_set_double_buffered is now deprecated, and we don't support
non-double-buffered widgets. This means that under normal circumstances,
paints are never outside of a begin_paint / end_paint sequence, which
natively-double-buffered backends like Wayland can't possibly support.
Without this information introspection-based consumers don't realize
they can include context information, but instead think that they
receive an extra gpointer argument (which they don't know how to
handle).

Add gdk_device_get_last_event_window(), and use to implement the window
tracking we need for synthesizing crossing events for sensitivity changes
and gtk grabs, rather than keeping the information in qdata and updating
it based when GTK+ gets events.
https://bugzilla.gnome.org/show_bug.cgi?id=726187
Try to do a better job of keeping example content
from being too wide. It is often rendered as <pre>
text so the only time we can wrap it is in the source.
It is best to full break lines at all punctuation and
to try to keep the width under 70 chars or so.
This makes it possible to move/resize client-side decorated windows that are
otherwise obscured by a GTK+ grab somewhere else, either a popover within the
window itself or a modal dialog above the window.
We now consider non-native windows non-opaque, which means any invalid
area in a subwindow will also be invalid all the way up to the nearest
native windows. We take advantage of this by ignoring all expose events
on non-native windows (which typically means just the toplevel) and instead
propagating down the draw() calls to children directly via
gtk_container_propagate_draw.
This is nice as it means we always draw widgets the same way, and it
will let us do some interesting ways in the future.
We also clean up the GtkWidget opacity handling as we can now always
rely on the draing happening via cairo.
We can't really just draw by walking down the widget hierarchy, as
this doesn't get the clipping right (so e.g. widgets doing cairo_paint
may draw outside the expected gdkwindow subarea) nor does it let
us paint window backgrounds.
So, we now do multiple draws for each widget, once for each GdkWindow,
although we still do it on the same base cairo_t that we get for the
toplevel native window. The difference is only the clipping, the rendering
order, and which other widgets we propagate into.
We also collect all the windows of a widget so we can expose them inside
the same opacity group if needed.
NOTE: This change neuters gtk_widget_set_double_buffered for
widgets without native windows. Its impossible to disable
the double buffering in this model.
Some utilities such as GIR and gtk-doc, initialize class vtables without
initializing GTK+, with composite templates accessing resources this
causes a hand full of unneeded warnings.
The workaround for now is the use a private function _gtk_ensure_resources()
which is both called while initializing GTK+, and at the beginning of
gtk_widget_class_set_template_from_resource() (the private function
ensures that the resource will only ever be registered GOnce).
Don't mention "auto mnemonics", since those methods are purely about
scheduling a delayed display, and that makes understanding the code a
bit harder.
https://bugzilla.gnome.org/show_bug.cgi?id=697144
When event capturing is enabled, stop propagating scroll events
at insensitive widgets, but don't handle them (don't return TRUE),
so they can bubble up again and reach their handling widgets.
I'll add a bunch of fixes for gcc complaining about
-Wmissing-declarations after finding a bunch of cases today where I had
forgotten to make functions static in the CSS code.
A thorn in those patches is G_DEFINE_TYPE() which doesn't allow making
the get_type() function static, so I added definitions for that function
above the G_DEFINE_TYPE().
After those patches, GTK should compile without warnings when this flag
is enabled.
Showing mnemonics immediately on modifier press can be annoying and
distracting when the user is just trying to Alt+Tab into another
application/window since the mnemonic will show up and quickly vanish
again when we receive the focus out event.
https://bugzilla.gnome.org/show_bug.cgi?id=672431
See inline comments for what it does. Its main use is figuring out if
something has been caused by GTK's caching of CSS properties or if it's
a different problem.
If the touch sequence happens on a window with GDK_TOUCH_MASK set,
a GdkTouchGrabInfo is created to back it up. Else a device grab is
only created if the sequence emulates the pointer.
If both a device and a touch grab are present on a window, the later
of them both is obeyed, Any grab on the device happening after a
touch grab generates grab-broken on all the windows an implicit
touch grab was going on.
This patch adds a capture phase to GTK+'s event propagation
model. Events are first propagated from the toplevel (or the
grab widget, if a grab is in place) down to the target widget
and then back up. The second phase is using the existing
::event signal, the new capture phase is using a private
API instead of a public signal for now.
This mechanism can be used in many places where we currently
have to prevent child widgets from getting events by putting
an input-only window over them. It will also be used to implement
kinetic scrolling in subsequent patches.
http://bugzilla.gnome.org/show_bug.cgi?id=641836
We automatically request more motion events in behalf of
the original widget if it listens to motion hints. So
the capturing widget doesn't need to handle such
implementation details.
We are not making event capture part of the public API for 3.4,
which is why there is no ::captured-event signal.
_gtk_widget_set_device_window() is suppose to make accounting of
the topmost widget under the device at each time, so avoid setting
it on virtual crossing events as the device is already in another
window.
Now that ATK no longer uses a key snooper but is invoked directly,
checking in advance for existing snoopers is wrong and stops ATK from
working.
Also: code reduction without performance loss == good thing.

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.
- add gtkmodulesprivate.h and move stuff there from gtkprivate.h
- add gtkprivate.c and move stuff there from gtkmain.c
- add gtkwin32.c and move stuff there from gtkmain.c
- don't redefine GTK_DATADIR and friends in gtkprivate.h
- have _gtk_get_datadir() and friends on all platforms
- remove the horrid hacks where gtkprivate.h can't be included,
or must be included later due to redefinition of the compile-time
directories
and finish the port to using the new modifier abstraction API.
This commit has some evilness, it uses the default display for
the lack of a widget context, and the change to gtkstock.c
is very ugly, but I can't think of anything better given
GtkStockItem needs an accel mask instead of a proper accel
string.
Add _gtk_button_event_triggers_context_menu() and use it instead
of checking for event->button == 3, so context menus are invoked
correctly on the Mac.
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.

It is now no longer possible to disable it.
This doesn't matter though because GTK will not instantiate a11y
objects until you actually use it. So nothing changes in practice.
* gtk/gtkmain.c: (gtk_init): Mention that argc and argv can be 0,
using the new text from the g_applicatoin_run() documentation.
There was already introspection annotation about that.
(gtk_init_check, gtk_init_with_args): Use the same text here.
See bug #643649 comment 2.
This commit does a number of things:
- remove some dead wchar configury from configure.ac and gdkconfig.h
- repurpose gdkconfig.h as header that contains GDK_WINDOWING_foo
macros for each included backend, include it in gdk.h and install
it in $includedir instead of below $libdir
- drop the backend from the library names
- build libgdk-3.0.la as a convenience lib and include it in libgtk-3.0.la
It does not yet enable building multiple backends at the same time.
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 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.

Rename the gtk_major_version() etc functions I introduced yesterday to
start with gtk_get. Avoids misleading results in client programs whose
developers that don't notice the change or the compiler warnings, and
when recompiling against gtk3 then use the function addresses as the
version numbers.
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.
Having variables exported from a DLL is slightly painful and
potentially error-prone on Windows, so let's try get rid of them now
when we can. Starting with these.
Fixes https://bugzilla.gnome.org/show_bug.cgi?id=620440 (Reported by
Marek Kašík), where the print dialog modality would impair the pop-up
window from getting events. Device GTK+ grabs gain in specificness.
