Functions dealing with native Xlib types were (skip)ed because
gobject-introspection did not have correct Xlib types declarations.
They are corrected now, so these GdkX11 functions can be enabled back
again.

It could happen that a cookie event has been already allocated/freed
in an event filter, as it can't be allocated a second time, all GDK
can do is skipping the event. Spotted by Guillaume Desmottes.
This function can be used to find the GdkDevice wrapping
an XInput2 device ID. For core devices, the Virtual Core
Pointer/Keyboard IDs (2/3) may be used.
This function can be used to find out the XInput2 device ID
behind a GdkDevice, mostly useful when you need to interact
with say Clutter, or raw libXi calls.
Fixes Bug 645993 - XIM has wierd behaviors. Some XIM modules
filter every key event, possibly replacing it with their own
one. These events usually have serial=0, so make
GdkDeviceManagerXI2 also listen on these.
This is already done in gdk_event_source_get_filter_window(), and
could lead to wrong event assignment if an event translator happens
to return a window for an event it doesn't handle.
This method can be implemented by event translators so they
return the right window from XGenericEventCookie events, as
ev->xany.window isn't meaningful for these.
GdkEventSource now also uses this to find out the right window
filters to apply.
The XI2 device manager was mistakenly setting the window user_time on
both ButtonPress and ButtonRelease, which meant that processes that
tried to launch another process based on the time of a ButtonPress
event would end up always focus-stealing-preventing the new app.

_gdk_device_get_axis_use() dates back to pre-sealing, when the
xi2 work began, this remaining can be gone with a public
gdk_device_get_axis_use() function already in place.
The metacity theme format allows to use colors from the current
GTK+ theme in window decorations. Since GTK+ now gained support
for dark theme variants, window managers using that theme format
(metacity, mutter, compiz via gtk-window-decorator) should be able
to use colors from the correct variant; so in case a variant is
requested, export it in the _GTK_THEME_VARIANT property on
toplevel windows.

XSendEvent doesn't currently work with XI2 events, so add code to
translate core events when they have the send_event flag.
(We still don't actually select for core pointer/keyboard events, so
we will only receive send_event events that are sent with a 0
event_mask.)

This code is a relic from GTK2 days and should not be necessary anymore,
as code now makes sure to only copy those parts of the window that are
not overlapped by parent windows.
By deleting it we fix potential issues with composited and translucent
windows copying the wrong data.

The monitor change detection code in _gdk_x11_screen_size_changed() and
process_monitors_change() goes to some length to make sure its only emitted
when there is an actual change to the data visible via the GdkScreen monitors
api.
However, commit 662e69ad added some code that always emits "monitors-changed"
in _gdk_x11_screen_size_changed when we have randr13 and get a ConfigureNotify
on the root window (even though we may already have emitted it in the
RRScreenChangesNotify event!).
As far as I can tell this is due to a comment in the bug referenced by the
commit (https://bugzilla.gnome.org/show_bug.cgi?id=601712#c4) where it says:
This version of the patch changes GdkDisplay to emit "monitors-changed" when
the primary monitor changes (see the change in _gdk_x11_screen_size_changed).
And, if you remove this part of the change the signal is not emitted when just
the primary is changed. However, this is not really the right approach. We
should just also check for if the primary changes in process_monitors_change()
to avoid spurious signal emissions.

If a level 1 key maps to a key value passed to
gdk_test_simulate_key(), raise the GDK_SHIFT_MASK flag so the reqested
key value is generated. Also add a regression test for this fix.
Previously we weren't installing the device headers when compiling
without XINPUT support. But we would include them from gdkx.h, so
essentially the build was broken.
With this patch the types will exist but not do anything.
The previous function gdk_drag_get_protocol_for_display() took native
window handles, so it had to be changed. Because it didn't do what it
was named to do (it didn't return a protocol even though it was named
get_protocol) and because it doesn't operate on the display anymore but
on the actual window, it's now called gdk_window_get_drag_protocol().
... and all APIs making use of it.
That code like it hasn't been touched in years, Google codesearch
didn't find any users and most importantly it's a horrendous API, so
let's just make it die instead of having to port it over to
non-GdkNativeWindow usage, which would be required for multi-backend
GDK.
http://mail.gnome.org/archives/gtk-devel-list/2011-January/msg00049.html
Use GdkWindow instead. This requires calling
gdk_x11_window_foreign_new_for_display(), so might cause a slight
performance penalty, but is required to be portable.
This function allocates the button mask, so free it after
use, or right before the next XIQueryPointer() call, as done
in gdk_x11_device_xi2_window_at_position().
mods_state->effective is not being set in XIQueryPointer() currently, so
use base|latched|locked instead, effective is nothing else than a shorthand
for these ORs, and these 3 values are set correctly anytime.
Prevents an Xlib warning on Xnest, or Xorg with xinerama, or other
non-RANDR-capable xserver. Reintroduce a have_randr12 field in
GdkDisplayX11 to avoid having to call XRRQuery{Extension,Version} twice,
and don't select randr 1.2 events if that's false.

We need to defer setting the default display until the
GdkDisplay is fully initialized. Also, short-circuit some
encoding conversions when creating windows, to avoid an
implicit dependency on the display being in the list of
displays yet.
This was an incomplete attempt to get rid of the custom free function.
Lets just keep it for now. Bug 637849, patch by Dan Winship.
Also add a test case for this function.
This is for compatibility reasons. We want to change APIs that operate
on X11 objects to take the X11 objects as arguments. However, this would
break a lot of APIs and we'd like to avoid this, so we play this little
trick (we will use the same trick for the other X11 objects). Also,
gobject-introspection and other bindings can correctly attach the
functions to the correct types as it is the same scheme that GDK2 used
for pixmaps, windows and drawables.
For GTK 4, we will remove this trick, so apps should properly cast their
objects right now.
Unfortunately, I don't think there is a way to use
GDK_DISABLE_DEPRECATED or similar macros to check for proper type casts
while compiling ensure compatibility with future GDK versions. I'm free
to consider them though.
Move everything dealing with compound text to be X11 specific
Only gdk_text_property_to_utf8_list and gdk_utf8_to_string_target
are kept across backends, so add vfuncs for these.
Also, remove the non-multihead-safe variants of all these.
Remove the --sync option and remove the possibility of backend-specific
commandline options altogether. --sync is being replaced by
a GDK_SYNCHRONIZE environment variable.
Moving the direct-access redefinitions of various macros
to gdkprivate-x11.h and use that header throughout in x11/.
Also remove a workaround for a long-fixed X server bug.
The X11 backend exports a number of symbols which are _-prefixed
(so don't become part of the gdk api), but are not named in a
way to prevent accidental clashes between backends.
The one API change here is that the gdk_xid_table functions
have been removed - they did not server an purpose, since the
xid table only stores windows anyway, and we already have a
lookup-by-xid function for windows.
These functions were trivial g_spawn wrappers in all backends
except for X11, and they can be easily replaced by
g_app_info_create_for_commandline + GdkAppLaunchContext.
Commandline arguments should go away altogether, but this one
goes first, since we then don't need to worry about
_gdk_windowing_substitute_screen_number anymore.
This commit hides the GdkDisplayManager instance and class structs,
adds vfuncs for listing displays, opening displays, and getting and
setting the default display. The X11 backend has a derived
GdkDisplayManagerX11.
The gdk_display_manager_get() function is responsible for deciding on
which of the compiled in backends to use. Currently, it consults the
GDK_BACKEND environment variable and falls back to x11.
Use the grab and ungrab vfuncs from the frontend instead of the
_gdk_windowing wrappers, and move some things around accordingly.
Again, only the X11 backend has been updated, other backends
need to be updated to match.
It turned out no vfuncs were necessary. I've decided to move
the screen member up to GdkVisual, since it is the same in all
backends. The X11 backend subclasses now, to add the X members
that it needs to keep track of. GdkVisual and GdkVisualClass
are hidden now.
This commit hides GdkDragContext and GdkDragContextClass, adds
vfuncs for most drag context functionality, and turns the X11 DND
implementation into GdkDragContextX11. We also add vfuncs to
GdkDisplay for gdk_drag_get_protocol and to GdkWindow for
gdk_drag_begin, and implemenet them for X11.
Other backends need similar treatment and are broken now.
Add a GdkDisplay::get_app_launch_context vfunc, and a
gdk_display_get_app_launch_context that for X11 returns a subclass.
For win32 and quartz, the implementations were trivial, so we
just return a new GdkAppLaunchContext without subclassing. Since
the type of the context now depends on the display,
gdk_app_launch_context_set_display is deprecated.
Running gnome-shell under valgrind, I saw the attached invalid write.
Basically we can destroy a window during event processing, and the old
window_remove_filters simply called g_free() on the filter, ignoring
the refcount. Then later in event processing we call filter->refcount--,
which is writing to free()d memory.
Fix this by centralizing list mutation and refcount handling inside
a new shared _gdk_window_filter_unref() function, and using that
everywhere.

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.
The xi2 device manager now handles slaves being detached and/or
attached to a master.
gdk_device_list_slaves() has been added so it is possible to
know how slaves relate with masters. The other backends (X11 and not)
don't neeed to to anything special here since their hierarchy is
fully flat.
When the slave device changes, the master takes the shape of the
new one, modifying its axes, this signal is more useful to catch
this situation than the n-axes property
This function may be used to know the hardware device that triggered
an event, it could resort to the master device in the few cases there's
not a direct hardware device to relate to the event (i.e.: crossing events
due to grabs)
gdk_enable_multidevice() has been replaced with gdk_disable_multidevice(),
so applications may call that function if they want to go back at the
previous behavior.
There would be usually little reasons to call that function, unless the
application is doing X calls itself that count on old fashioned core
devices.
Scanner doesn't detect this case correctly because it's a typedef;
work around it here by explicitly specifying that it's caller
allocates. See bug 636393 for the scanner issue.
One less magic function. Also refactored it to make it easier to
implement. It now returns TRUE if it beeped and FALSE if it failed to do
so. A default implementation exists that just returns FALSE for all the
backends that can't beep windows (read: everything but X11 with XKB -
and why on earth do keyboard libs implement beeping?)
Trying to get rid of all the _gdk_windowing_something() functions that
we expect backends to magically know about and instead put them in a
proper interface (mostly GdkWindowImplClass).
An event filter may add or remove filters itself. This patch does
two things to address this case. The first is to take a temporary
reference to the filter while it is being used. The second is
to wait until after the filter function is run before determining
the next node in the list to process. This guards against
changes to the next node. It also does not run functions
that have been marked as removed. Though I'm not sure if this
case can arise.

Since what we are doing is turning an icon with alpha into a
no-alpha icon + mask for legacy window managers, it makes more sense
to use the system visual than the window's visual, which might
be ARGB.
https://bugzilla.gnome.org/show_bug.cgi?id=634821
gdk_settings_map needs to be updated when gdk_settings_names is changed,
and it's easier to add the setting at the end, so we don't need to
recalculate everything.
Really fixing:
https://bugzilla.gnome.org/show_bug.cgi?id=634697
In this case, gnome-terminal sets an RGBA visual on its window,
and we need to be careful when creating the icon pixmap, to create
the pixmap with the same depth as the visual, or we risk a BadMatch
from XRenderCreatePicture deep inside cairo.
Allow -1 for the hotspot coordinates in gdk_cursor_new_from_pixbuf,
if the pixbuf contains the x_hot/y_hot options with appropriate values.
Bug #632140.
In particular, the following functions are gone:
- gdk_screen_get_default_colormap()
- gdk_screen_set_default_colormap()
- gdk_screen_get_system_colormap()
- gdk_screen_get_rgba_colormap()
This way, we can specify a colormap when constructing windows. And ew
must do that to avoid BadMatch from XCreateWindow when we use a
different visual.
Also add a priv pointer to GdkVisual and use it for the GdkVisualPrivate
structure. Then Make GdkVisualPrivate actually private to
gdkvisual-x11.c and make other callers use proper function calls to
access it.
Direct and TrueColor visuals don't alloc colors, so they don't need to
fiddle with colormaps. Just copy the code that computes the pixel value
from gdkcolor-x11.c and use it. For other visual types, don't set the
background color and fallback to background = None.
No more GdkPixmap to store the icon and its mask, but instead use cairo
surfaces. Also render the icon into the surfaces using Cairo instead of
gdk_pixbuf_render_threshold_alpha().
Now the window background is a cairo_pattern_t. The backends will try to
set this as good as they can on the windowing system, but no guarantees
are made on wether the windowing system supports the pattern.
Also gets rid of GDK_NO_BG as undefined behavior is not a good idea to
support, and GDK_NO_BG effectively made the window's contents undefined.
It wasn't effectively used in GTK anyway.
Basically copies the code for setting the WM icon hint from GtkWindow to
GdkWindow. This achieves the following:
- Putting this X11 specific code into the X11 backend
- Enables removal of gdk_window_set_icon()
- Gets rid of Pixmap/Bitmap usage outside of GDK.
trap->end_sequence is the first serial for which we don't
ignore errors anymore, so we know the trap is dead if
end_sequence <= processed_serial.
Bug 629608
Currently fprintf(stderr, ...) is used for X error and X IO errors
(unless compiled with debugging, in which case g_error() is used for
X errors.)
But if an application is redirecting log messages, we really want
X errors to appear in that same log, so it's better to use a g_logv()
variant.
Though g_warning() isn't really appropriate for "lost connection to the
server", G_LOG_LEVEL_INFO isn't part of the "prefixed log levels"
so will produce output without the application name and PID.

When an error occurs with nested traps in place, only the innermost
trap should have the error code stored in it; outer traps are
shielded by the inner trap.
https://bugzilla.gnome.org/show_bug.cgi?id=629608
* don't lose track of previous X error handler
if nested traps are pushed
* free any remaining traps when display
is finalized
Test will fail unless bug 630032 is closed so
gdk_display_close() works.
https://bugzilla.gnome.org/show_bug.cgi?id=630033
* _gdk_device_set_associated_device() did not allow NULL device
* GdkDisplay should dispose device manager to avoid devices
trying to touch the display in finalize
* GdkDeviceManagerXI did not ref devices in id hash
* GdkDisplayX11 did not ref devices in ->input_devices
* add per-display gdk_x11_display_error_trap_push()
(X11-specific because gdk_error_trap_push() probably
should have been)
* make gdk_error_trap_push() handle only GDK displays
not displays opened without a GDK wrapper
* make gdk_error_trap_pop() and gdk_x11_display_error_trap_pop()
automatically sync only if needed, so manual gdk_flush() is not
required
* add gdk_error_trap_pop_ignored() which just asynchronously
ignores errors, so never needs to sync
* add G_GNUC_WARN_UNUSED_RESULT to plain pop(), because
if you use plain pop() and don't need the return value,
the async gdk_error_trap_pop_ignored() should be used
instead. This results in lots of warnings to clean
up in a later patch.
The main objective here was to avoid the need to sync just
to ignore an error. Now, syncing is automatic, and only
happens when we need to know the error code.

Add the composite overlay window to the cache, as this can be a reasonable Xdnd proxy as well.
This is only done when the screen is composited in order to avoid mapping
the COW. We assume that the CM is using the COW (which is true for pretty
much any CM currently in use).
https://bugzilla.gnome.org/show_bug.cgi?id=601731
This was the last exported variable; it wasn't multihead safe,
and there's easy replacement with gdk_display_get_default().
Also drop the GDK_DISPLAY() macro which was just a wrapper around
the variable.
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.
Bug 628656 - _gdk_windowing_get_startup_notify_id memory leak
get_display_name() returns a newly allocated string, which was being fed
directory info a g_strdup_printf() call.
While X11 surfaces can be resized, this is not the case for Quartz
surfaces. Instead of resizing we will invalidate the surface instead.
By giving _gdk_windowing_set_cairo_surface_size() a boolean return
value, we can signal back whether or not resizing was possible. If not
possible, we invalidate the surface.
The window move code needs special attention for multiple reasons:
- invalid areas for expose events need to be modified
- self-copy is not supported by Cairo
- in X11, copying from an overlapped Window might cause unexposed areas
to be copied in, spo expose events for those need to be generated.
This was all special cased in various parts of the code. By making it an
explicit vfunc, we can work around it.
