If the tablet gets removed/freed while there are pad events in flight,
we leave a dangling pointer from the pad to the tablet, which may
lead to invalid reads/writes when handling the pad event(s).
If you run weston with the headless backend, you get a Wayland
display with no seat, which is just fine by the protocol.
gdk_display_get_default_seat() returns NULL in this case. Various
widgets assume that we always have a seat with a keyboard and a
pointer, since that is what X guarantees. Make things survive
without that, so we can run the testsuite under a headless
Wayland compositor.
In the gtk-demo drag-and-drop demo i can't drag anything, all I get
is:
(gtk4-demo:358993): Gdk-CRITICAL **: 09:36:19.617: Surface 0x7e1bb0 has not been mapped in GdkSeatGrabPrepareFunc
This is because GdkX11Drag.ipc_surface is not considered mapped, even
though we called gdk_x11_surface_show() on it, because the
GDK_SURFACE_STATE_WITHDRAWN flag is still set.
I added calls to gdk_synthesize_surface_state() to match what
e.g. show_popup() and gdk_x11_toplevel_present() does.
Tracking of those broke sometime along the gdk cleanups, so we
started missing some GDK_GRAB_BROKEN events from being emitted
(eg. after a button press/implicit grab triggers an active grab).
Implicit grabs are only added if there's no prior grab (either
implicit through other button presses, or explicit), in order to
keep accounting correct, make those prevail.
Conditionally check whether the Vulkan headers version defines
VK_RESULT_RANGE_SIZE, and avoid using it for version >=140. The
following comming in Vulkan-Headers has removed the enum value:
0c5351f5e9 (diff-4febd94c0666d59030d8b1dd20c72403)
When I removed the 0-termination for the entries for
each keyval, I remove the code initializing the key,
but accidentally left the code that adds it to the
array, so gdk_keymap_get_cached_entries_for_keyval
returns one extra, uninitialized value at the end
of the array. Stop doing that.
We currently calling gdk_display_map_keyval up to
once per key event per shortcut trigger, and that function
does an expensive loop over the entire keymap and
allocates an array. Avoid this by caching the entries
in a single array, and have a lookup table for finding
the entries for a keyval.
To do this, change the GdkKeymap.get_entries_for_keyval
signature, and change the ::keys-changed signal to be
RUN_FIRST, since we want to clear the cache in the class
handler before running signal handlers. These changes are
possible now, since keymaps are no longer public API.
In the absence of icon themes (such as in a freshly
created toolbox container), we should not just fall back
to "no cursor", since that makes it hard even to close
the application. Fall back to an included default cursor
of last resort.
Provide a fallback cursor of last resort. Otherwise,
we end up with no visible cursor if there is no
cursor theme installed, wihch is less than helpful.
If the wl_surface receiving touch events is destroyed, we will get no
wl_touch.up event to remove the touchpoint from our internal accounting.
Check for this, and drop touchpoints happening in surfaces that do
disappear during operation.
The api to configure surfaces is now GdkToplevelLayout
and GdkPopupLayout. Unfortunately, there's still quite
a bit of internal use of GdkGeometry that will take some
time to clean up, so move it go gdkinternals.h for now.

We don't create a grabbing popup if it's not the top most one, as that
is a protocol violation, and complain if anything attempts to do it.
What we didn't do is handle this gracefully in the code that tries to
create said popup.
Fix this by dropping the attempt to show the popup on the floor, instead
of setting various state making it look like it succeeded. This won't
actually fix anything, but it'll result in a bit more accurate warnings
logged, as the state more correctly corresponds to the reality.
When we autohide a popup surface with a grab, hide all other auto hiding
popups up the popup chain. The end result is that when you click outside
a menu with submenus open, the whole menu chain is dismissed.
GdkEvent has been a "I-can't-believe-this-is-not-OOP" type for ages,
using a union of sub-types. This has always been problematic when it
comes to implementing accessor functions: either you get generic API
that takes a GdkEvent and uses a massive switch() to determine which
event types have the data you're looking for; or you create namespaced
accessors, but break language bindings horribly, as boxed types cannot
have derived types.
The recent conversion of GskRenderNode (which had similar issues) to
GTypeInstance, and the fact that GdkEvent is now a completely opaque
type, provide us with the chance of moving GdkEvent to GTypeInstance,
and have sub-types for GdkEvent.
The change from boxed type to GTypeInstance is pretty small, all things
considered, but ends up cascading to a larger commit, as we still have
backends and code in GTK trying to access GdkEvent structures directly.
Additionally, the naming of the public getter functions requires
renaming all the data structures to conform to the namespace/type-name
pattern.
For the X11 backend, keep a list of monitors for which the surface
intersects the monitor area.
Whenever the X11 surface is configured, check against the list of
monitors to determine whether it enters a new monitor or if it left a
monitor, to emit the corresponding ::enter/leave-monitor signals just
like a Wayland compositor would.
As monitors can be added, removed or reconfigured at any time, redo
those checks whenever any of these events occur.
Stop rewriting key and focus events on the GDK side.
Instead deliver them as they are, and propagate them
from the root on the gtk side, in gtkmain.c. And
stop complaining about focus events on popups - we
can just ignore them if we have no use for them.
A toplevel will only ever be transient-for to another toplevel, and only
a toplevel will ever be transient-for, so move the field into the
GdkWaylandToplevel, and make it a pointer to another GdkWaylandToplevel.
We them up there, so that code higher up compared to where they are
defined now can make use of them. Also add a few macros for type
checking and casting.
The third version of xdg-shell introduces support for explicit popup
repositioning. If available, make use of this to implement popup
repositioning.
Note that this does *NOT* include atomic parent-child state
synchronization. For that,
https://gitlab.freedesktop.org/wayland/wayland-protocols/issues/13 will
be needed.
This currently uses my own fork of wayland-protocols which adds meson
support, so that we can use it as a subproject. Eventually when
wayland-protocols' meson support lands upstream, we should change it to
point there.
Silence some meson warnings while at it to make CI happy.
This also bumps the glib requirement, since g_warning_once() is used.
We don't need all of them, only the ones that contain public API. This
allows us to reduce the chance of a stray symbol getting incorrectly
added to the introspection data.
This removes the use of the context menu and shift group
intents in gdkevents.c. If it turns out to be important,
we need to introduce vfuncs for gdk_event_triggers_context_menu
and gdk_event_matches.
Add all of the keyboard translation results in the key event,
so we can translate the keyboard state at the time the event
is created, and avoid doing state translation at match time.
We actually need to carry two sets of translation results,
since we ignore CapsLock when matching accelerators, in
gdk_event_matches().
At the same time, drop the scancode field - it is only ever
set on win32, and is basically unused in GTK.
Update all callers.
The win32 backend is using GDK_MOD2_MASK for AltGr,
so define GDK_MOD2_MASK locally to keep this working,
but remove any mention of GDK_MOD3_MASK,...,GDK_MOD5_MASK.
With C compilers defaulting to -fcommon, this isn't an issue, but
upcoming compilers (GCC 10 and Clang 11) will default to -fno-common,
ending up with duplicate definitions of these variables.
With the removal of `gdk_seat_grab` we do not need to keep the
definitions of `GdkGrabStatus` and `GdkGrabOwnership` public.
Move those definitions to become internal only.
When we reconfigure, `configure_file()` is called again, and
`*.gresource.xml` files are regenerated, which causes many (all?)
binaries to be relinked. Now we only write those out if the contents
actually changed (or if the output didn't already exist).
This is exactly what Meson already does with `configure_file()` when
`command:` is not used.
While we're at it, also do the same for `gen-c-array.py` and
`gentypefuncs.py` for completeness. Now even if the input to those
changes, re-building of those custom targets may not result in
relinking if the outputted C files have the same contents.
When we `Alt+Tab` away from a GTK application, it loses keyboard focus.
If we don't clear the modifiers, events from other devices that we
receive while unfocused will assume `Alt` is still pressed. This results
in e.g. Firefox navigating through the history instead of scrolling the
page when using the mouse wheel on it.
We don't get any information about modifiers while we are missing
keyboard focus, so assuming no modifiers are active is the best we can
do.
The shell sends us a modifier update immediately before we regain
keyboard focus, so the state shouldn't get out of sync.

Win32 backend doesn't have support for inhibit shortcuts, yet it needs
support the standard set of GdkToplevel properties.
Add support for the "inhibit-list" object property to GdkToplevel on
win32.
Broadway doesn't have support for inhibit shortcuts, yet it needs to
support the standard set of GdkToplevel properties.
Add support for the "inhibit-list" object property to GdkToplevel on
Broadway.
On X11, there is no such equivalent to the inhibit shortcut protocol
found on Wayland.
To implement the inhibit_system_shortcuts API on X11, we emulate the
same behavior using grabs on the keyboard.
To avoid keeping active grabs on the keyboard that would affect other
X11 applications even when the surface isn't focused, the X11
implementation takes care of releasing the grabs as soon as the toplevel
loses focus.
With the current implementation, we use a `wl_seat` as the key for our
internal has table where we store the Wayland shortcuts inhibitors.
There is however no technical reason for this, and we could use a
GdkSeat instead, which will ease the implementation of the GdkToplevel
shortcut inhibition API.
With the removal of grabs from the public API, we need a replacement API
to let applications bypass system keyboard shortcuts.
A typical use case for this API is remote desktop or virtual machine
viewers which need to inhibit the default system keyboard shortcuts so
that the remote session or virtual host gets those instead of the local
environment.

GTK defines various types that are meant to be derivable only within GTK
itself, and "final" from the perspective of consumers of the GTK API.
The existing macros defined by GObject, such as G_DECLARE_FINAL_TYPE and
G_DECLARE_DERIVABLE_TYPE, lack this functionality.
While we wait for GObject to get this kind of macro, we should define
our own.
