The condition we check for to catch X servers going away
may not be accurate anymore, and the warning shows up in
logs, causing customers to be concerned. So, be quiet by
default, unless the user explicitly asked for a message.
The DnD code for X11 adds the composite overlay window (aka COW) to the
cache.
Yet the X11 requests to get and release the COW may trigger XErrors that
we ought to ignore otherwise the client will abort.
Fixes: #3715
When setting a window's background to ParentRelative on X11, the window
depths must match to avoid a BadMatch error. Query the X server for the
parent window rather that relying on the parent passed to
gtk_window_new() to prevent crashes with reparented windows.

Reading form the back buffer is not allowed on software renderers,

When a device is added, there are two references to it by the device
manager, the initial one and the one used for the id_table. Removing a
device only removed the reference added by the id_table resulting in the
GdkDevice being leaked.

Window scale can change at runtime. If cairo_surface is already
created for root window gdk_pixbuf_get_from_window will return
wrong image.
_gdk_x11_screen_set_window_scale already updates window_scale for
root window, update also cairo_surface device scale.

Otherwise the icon "jumps" to the cursor position with its top left when

I was not getting any gtk+ profile markers output from the frame clock
when I was profiling an OpenGL app (gnome-hexgl). I debugged this and
it turns out that the profiling depends on getting the _NET_WM_FRAME_TIMINGS
event from the compositor, and once we switched to OpenGL rendering
this never appeared.
It turns out the reason it didn't is that the compositor only does
so if the client increases the counter tied to the window, and the
x11 gdk code has this optimization where if we do a draw pass
but nothing is actually drawn we don't update the counter.
Unfortunately the detection of whether something was draw or not
is based on some cairo surface hack that breaks when we render with
OpenGL instead. The fix is to just always update the counter if
we're drawing with OpenGL.
This was added with https://bugzilla.gnome.org/show_bug.cgi?id=148032
to make gtk compile against X11R5, see commit 3b9a31df0
That release is >20 years old now, so we can safely remove it.
The motivation for this is to remove any checks that we don't have in the
meson build.
We clamp to 32767 when creating a new X11 GdkWindow due to larger sizes
not being supported, but still try to resize to larger when
gdk_window_resize() is called. Fix this by clamping in both places.
This fixes an issue in mutter where ridiculously sized Java windows
would not show up.
Previously, the manufacturer property of the GdkMonitor was NULL,
and having at least PNP id at GdkMonitor.manufacturer makes it
possible to distinguish between different monitors programmatically.
This is a backport of the GdkProfiler from master. It does not include
the pixel bandwidth numbers that come from gdkdrawcontext.c since there
does not seem to be an analog in 3.x.
Additionally, this implements the recent changes for SYsprof's D-Bus
profiler API which adds a Capabilities property and an options hash-table
to the D-Bus interface for forward portability.
If we set c_marshaller manually, then g_signal_newv() will not setup a
va_marshaller for us. However, if we provide c_marshaller as NULL, it will
setup both the c_marshaller (to g_cclosure_marshal_VOID__VOID) and
va_marshaller (to g_cclosure_marshal_VOID__VOIDv) for us.
Add private API to GDK to move these variables from the environment into
static scope. Also move the DESKTOP_STARTUP_ID validation here to reduce
code duplication.
Use constructors to read them as early as possible; however, do not
unset them until first requested. This avoids breaking gnome-shell and
gnome-settings-daemon, which want to use the DESKTOP_AUTOSTART_ID in
their own gnome-session clients.

Tools on the same physical item have the same serial number, so the eraser
and the pen part of a single pen share that serial number. With the current
lookup code, we'll always return whichever tool comes first into proximity.
Change the code to use the hw id in addition to the serial number, this way we
can differ between two tools.
Generic tools (Bamboo, built-in tablets) always have the same serial number
assigned by the wacom driver. This includes the touch tool when the wacom
driver handles the touch evdev node (common where users require the wacom
gestures to work).
When the first device is the touch device, a tool is created with that serial.
All future tools now return the touch tool on lookup since they all share the
same serial number. Worse, this happens *across* devices, so the pen
event node gets assigned the touch tool because they all have the same serial.
Since we don't actually care about the touch as a tool, let's skip any unknown
tool. This captures pads as well.
Any wacom device currently sets the tool type to UNKNOWN. The wacom driver has
a property that exports the tool type as one of stylus, eraser, cursor, pad or
touch. Only three of those are useful here but that's better than having all
of them as unknown.
G_GNUC_END_IGNORE_DEPRECATIONS terminates the if statement and does not
consider the following block to be part of the if. So that block was
always taken irregardless of the pattern.
Fixes#1280
We don't want to set ParentRelative when:
- the parent window is NULL
In that case we are unsure about the depth, so better err on the side
of caution and avoid a BadMatch by accepting ugly output.
- the cairo pattern is in an error status
This should never happen - unless you start up in OOM - but better
be safe than sorry.
Might help with the spurious crashes in #1280.
Fixes#1280, tray icons not drawing background. This is a magic pattern only
usable for gdk_window_set_background_pattern() that sets the underlying
X window's background to ParentRelative.
According to the XEmbed specification, a window should be created
"elsewhere" and then reparented into the target parent window. Instead,
GTK+ creates the window directly in desired target parent window. This
allows some races to occur.
Another program that does not follow XEmbed is tabbed. XEmbed requires
an _XEMBED_INFO property on the to-be-embedded window, but tabbed does
not check for this property. Thus, as soon as GTK+ creates its window,
tabbed starts managing this window and now GTK+ setting up the window
races with tabbed starting to manage the window.
If tabbed is fast enough to map the window, GTK+ never sees a MapNotify
event, because it did not yet select StructureNotifyMask on its window.
This results in a black window inside of tabbed.
Note that this cannot really be fixed in tabbed, since XEmbed says that
the _XEMBED_INFO property must be already present when the window
appears. Thus, patching tabbed to wait for _XEMBED_INFO to appear is not
something that the spec requires/allows.
Instead, this commit changes GTK+ so that it directly sets the right
event mask when the window is created. This means that there is no more
race between tabbed mapping the window and GTK+ selecting
StructureNotifyMask.
Note that the proper fix would be to do as XEmbed requires: Create the
window elsewhere and then reparent it into the target window. However,
that would require a more invasive patch, so this commit only takes the
"easy approach" of fixing this one race. Hopefully, all the other races
that can occur during window setup are harmless, because the
embedder/socket will hopefully watch for PropertyNotify events as
needed.

In 01455399e8 ("gdk: do not deactivate surface on keyboard grabs"), we
made gdk avoid deactivating surfaces when another application takes a
keyboard grab, by using has_focus_window instead of has_focus. That however
broke activating surfaces when the gdk application acquired a grab itself,
in which case has_focus_window is false but has_focus is true.
We thus actually need to use both: surfaces should be activated either
because we have normal keyboard focus, or because we grabbed the keyboard.
This also renames HAS_FOCUS to APPEARS_FOCUSED to better reflect its
role.

When pressing e.g. a window manager shortcut, which acquires keyboard grab,
Xorg would send FocusOut NotifyGrab then FocusIn NotifyUngrab. Currently
gdk would then deactivate the current surface, which makes accessibility
screen readers think that we have switched to a non-accessible application
and came back again, and thus reannounce the application frame etc. which we
don't want when e.g. just raising volume.
And actually, receiving FocusOut NotifyGrab does not mean losing the
X focus, it only means an application aqcuired a grab, i.e. it is
temporarily stealing keyboard events. On Wayland, this isn't even
notified actually.
This commit makes gdk only deactivate surfaces when there was an actual
focus switch to another window, as determined by has_focus_window (instead
of just has_focus), which happens either normally through FocusOut with
NotifyNormal, or during grabs through FocusOut with NotifyWhileGrabbed.

Epoxy 1.4 has new ad hoc API that we can use to check whether GLX is
available on the current system.
If we didn't use this API, we'd have to manually dlopen libGL (or its
equivalent on different OSes) and check if it had GLX symbols; since
Epoxy already does all of this internally, we can simply ask it instead.

This state flag is used in several places in GTK+, for example to
ignore RESIZE_INC hints if tiled. Setting it is also necessary for
backwards compatibility with applications that changed their behaviour
when tiled, such as GNOME Terminal and its MATE fork.

Commit c415bef5de introduced support for the new _GTK_EDGE_CONSTRAINTS
atom. If the compositor supports that atom, however, we were always
setting the tiled state, even if no actual tiling information is
available, where the correct action is to completely remove any traces
of the tiled state.
Fix that by correctly removing the tiled state when compositor supports
_GTK_EDGE_CONSTRAINTS Xatom.
