When an animated cursor was set and the previous cursor animation delay
happened to be the same, we wouldn't restart the animation timeout and
just return G_SOURCE_CONTINUE assuming the timer would continue. This
assumption is however only valid if the function was called from the
timeout, which is not the case.
Instead also arm the timer also if there is no previous timer active.
gdk_wayland_*_grab()/ungrab() would emit crossing events which translate
as focus_in/focus_out events for keyboard.
However, the ungrab() functions compare the native toplevel as this is
what gets the Wayland pointer enter/leave events with the grab surface,
so if the grab is issued on a child gdk surface, those won't match and
we would emit more focus_out events than focus_in.
This means that a widget such as spice-gtk which issues a keyboard grab
whenever the pointer enters the surface and releases the grab when it
leaves the surface would get uneven numbers of focus_in/focus_out
events.
Also, gdk_wayland_seat_ungrab() would not emit crossing events for
keyboard devices, whereas gdk_wayland_device_ungrab() does, which adds
even more potential discrepancies between focus_in/focus_out events.
To solve this problem, introduce two new helper functions which check
the relevant native surfaces to emit crossing events when needed that
get called evenly from both gdk_wayland_seat_grab()/ungrab() and gdk
_wayland_device_grab()/ungrab() APIs.

Instead of tracking offers in GdkWaylandSelection objects, track the
pending offer in the GdkWaylandSeat and pass it to the GdkDragContext
once we get an enter event.
The header linux/input.h used by GDK is specific to Linux. It is
possible to get a few Linux headers on FreeBSD by installing v4l_compat,
but it is usually better to use the one shipped with FreeBSD.
We prefer dev/evdev/input.h to linux/input.h here, so it will always use
dev/evdev/input.h on FreeBSD regardless of v4l_compat.

Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.
The GDK_POINTER_MOTION_HINT_MASK enumeration value is gone, but we're
still keeping around the "is_hint" field in GdkEventMotion, even though
every backend sets it to `false` — except for the core X11 device
manager.
The main GDK thread lock is not portable and deprecated.
The only reason why gdk_threads_add_timeout() and
gdk_threads_add_timeout_full() exist is to allow invoking a callback
with the GDK lock held, in case 3rd party libraries still use the
deprecated gdk_threads_enter()/gdk_threads_leave() API.
Since we're removing the GDK lock, and we're releasing a new major API,
such code cannot exist any more; this means we can use the GLib API for
installing timeout callbacks.

BTN_STYLUS3 is defined by the Linux 4.15 kernel and is sent when the
third button on a stylus is pressed. At the moment, only Wacom's "Pro
Pen 3D" has three stylus buttons. Pressing this button triggers a button
8 event to be sent under X11, so we use the same mapping here.
https://bugzilla.gnome.org/show_bug.cgi?id=790033
As far as possible, use per-display debug flags.
This will minimize the debug spew that we get from
the inspector if it is running on a separate display.
Without selections, drags can't have them either.
Also included is removing the selection from GtkSelectionData.
Includes a bunch of crude cleanups to Wayland code that no longer has to
care about selection atoms.
It won't stand true anymore that the GdkEventType argument is the
first field of the GdkEvent* structs. All callers have been updated
to use event->any.type instead.
Traditionally (and on most backends) there's a single master pointer driven
by all pointing devices. The notable exception is Wayland though, where
master pointing devices are created per capability in the case of
pointer/touch, and one for each drawing tablet.
This function call makes it easy to access all these.
https://bugzilla.gnome.org/show_bug.cgi?id=790920
I decided to put this in a custom subclass, because then I could keep
the whole gtk primary protocol self-contained.
The other option would have been reusing GdkWaylandClipboard, but that
didn't seem worth it, especially because that code needs to interact
with the DND machinery, while the primary doesn't.
We must reset the image delay when stopping the timeout,
otherwise the code setting it up thinks it is still running.
This fixes cursor animation only working for the very first
enter of a widget with an animated cursor, as seen in the
cursors example in gtk4-demo.
Change constructors to reflect that.
While doing so, also add a fallback argument to the cursor constructors,
so it is now possible to create cursors with fallback.
This patch makes that work using 1 of 2 options:
1. Add all missing enums to the switch statement
or
2. Cast the switch argument to a uint to avoid having to do that (mostly
for GdkEventType).
I even found a bug while doing that: clearing a GtkImage with a surface
did not notify thae surface property.
The reason for enabling this flag even though it is tedious at times is
that it is very useful when adding values to an enum, because it makes
GTK immediately warn about all the switch statements where this enum is
relevant.
And I expect changes to enums to be frequent during the GTK4 development
cycle.
Interpret NULL as "root window" here - we only have one
screen nowadays, so there is no choice involved, and this
will let us avoid dealing with the root window in the
fontend code.
This adds support for the shortcut inhibitor protocol in gdk/wayland
backend.
A shortcut inhibitor request is issued from the gdk wayland backend for
both the older, deprecated API gdk_device_grab() and the new gdk seat
API gdk_seat_grab(), but only if the requested capability is for the
keyboard only.

Adds support for creating scroll events from Wayland tablet wheel events.
Even though no Wacom tablet puck has a smooth-scrolling wheel, both event

https://bugzilla.gnome.org/show_bug.cgi?id=783716
If a tablet device is used to perform actions like window moving or resizing,
GTK must provide the correct implicit grab serial number over Wayland to Mutter
in order for the action to succeed. This commit adds tablet support to the
implicit serial getters.
https://bugzilla.gnome.org/show_bug.cgi?id=777333
Under Wayland, when multiple keys are pressed and the user releases a
key, key repeat should continue unless the key released is the one
currently repeating.
In the case of:
- key1 press
- key1 repeat
- key2 press -> key1 repeat stopped
- key2 repeat
- key2 release
The behavior should be to cancel keyboard repeat, though key1 is still
held down. This is consistent with prior X11/XWayland behavior.
The following also must work:
- key1 press
- key2 press
- key2 release
- key2 press
- key1 release
- key2 should continue to repeat
The fix for bug #778019 should continue to work:
- key1 press
- key1 repeat
- key2 press -> key1 repeat stopped
- key1 release
- key2 should repeat
The choice to change the counter nkeys to the flag repeat_active
helps to solve the second test case.
https://bugzilla.gnome.org/show_bug.cgi?id=781285
With Wayland, GDK_DEBUG=events would log key events but not explicitly
state whether the event is a key press or release, or if it's
originating from a key repeat.
Add some more verbosity to make sure these informations are logged on
key delivery when GDK_DEBUG is set.
https://bugzilla.gnome.org/show_bug.cgi?id=781767
Make sure to clear up the number of keys being pressed on enter/leave so
that we don't end up with leftovers if a new window is mapped by a
keyboard shortcut.
https://bugzilla.gnome.org/show_bug.cgi?id=779374
The key repeat is stopped as soon as a key is pressed, so if the user
quickly presses a key while another is already pressed and being
repeated, key repeat gets cancelled:
- key1 press
- key1 repeat
- key2 press -> key1 repeat stopped
- key1 release
- key 2 is not repeated even though it's kept depressed
This is a different behavior from X11, which confuses migrating users.
To mimic the X11 behavior, keep track of the number of keys pressed
simultaneously and cancel key repeat only when none is pressed.
This way, if a user pressed a key while another one is being repeated,
the new key press can possibly be repeated as well.
Bugzilla: https://bugzilla.gnome.org/show_bug.cgi?id=778019
Elsewhere we already go through the keymap to get modifiers so we
should do the same here. In fact, this was relying on xkb modifier
mask values being bitwise compatible with GdkModifierType which isn't
necessarily true.
https://bugzilla.gnome.org/show_bug.cgi?id=770112
These complicate a lot of GdkWindow internals to implement features
that not a lot of apps use, and will be better achieved using gsk.
So, we just drop it all.
xdg_shell v6 allows grabless popups, whose behavior is not that
different from override redirect windows with no grab to take
keyboard input (and pointer events outside).
This means we can relax the requirement to have a grab before
creating an xdg_popup. The warning is still useful to have so
people stop relying on gdk_window_show();gdk_device_grab() being
an ok pattern to popup a window, it's been moved to wayland
implementation of gdk_device_grab() instead, so we warn if trying
to grab a GDK_WINDOW_TEMP window that's already visible.
https://bugzilla.gnome.org/show_bug.cgi?id=771694
And with it, gtk_widget_get_visual() and gtk_widget_set_visual() are
gone.
We now always use the RGBA visual (if available) and otherwise fall back
to the system visual.
The wayland tablet protocol allows notifying the compositor with
descriptions of the actions performed by each tablet element. This
API call allows to hook up in to this wayland-specific feature.
https://bugzilla.gnome.org/show_bug.cgi?id=770026
These devices are kind of an strange case. Their "master" device is
the keyboard, because they share toplevel focus with it, regardless
of stylus focus. Nonetheless, they are only expected to send the
GdkEventPad* set of events.
https://bugzilla.gnome.org/show_bug.cgi?id=770026
This is a subclass of GdkWaylandDevice that implements GdkDevicePad,
all pad features are looked up from the info obtained through the
tablet v2 interface.
https://bugzilla.gnome.org/show_bug.cgi?id=770026
An xdg-popup requires a serial that the compositor will compare against
its own serial and will dismiss the popup if it doesn't match.
gtk+ uses either a pointer or touch serial for its helper function
_gdk_wayland_seat_get_last_implicit_grab_serial() but if the menu is
triggered before the user has had any pointer or touch interaction with
the client, using a keyboard shortcut, there is neither pointer nor
touch serial available, and gtk+ will use 0 as the default.
As a result, the compositor will instantly dismiss the xdg-popup. In
this case, gtk+ should use the keyboard serial instead.
Track keyboard serial as well and use the keyboard serial as the value
if there is no newer pointer or touch serial available.
https://bugzilla.gnome.org/show_bug.cgi?id=768017
Only update to using v2 headers/structs. The incompatible changes
to tool events are dealt with in the next commit. Pads aren't handled
in this commit either.
On X11, device_query_state() uses XIQueryPointer() which will return a
child window only if the pointer is within an actual child of the given
window.
Wayland backend would return the pointer->focus window independently of
the given window, but that breaks the logic in get_device_state() and
later in gdk_window_get_device_position_double() because the window is
searched based on coordinates from another window without sibling
relationship, breaking gtkmenu sub-menus further down the line.
Fix the Wayland backend to mimic X11's XIQueryPointer() to return a
child only if really a child of the given window.
That's the most sensible thing to do to fix the issue, but the API here
seems to be modeled after the X11 implementation and the description of
gdk_window_get_device_position_double() is not entirely accurate.
https://bugzilla.gnome.org/show_bug.cgi?id=768016
The Wayland protocol does not share XI2's wealth of information
about individual devices, but it does provide discriminating
information about the source for scroll events. Pass this on to
the application by creating separate slave devices for these,
and setting them as source device on the scroll events.
These devices can be discriminated by their input-source property:
wheel - GDK_SOURCE_MOUSE
finger - GDK_SOURCE_TOUCHPAD
continuous - GDK_SOURCE_TRACKPOINT
https://bugzilla.gnome.org/show_bug.cgi?id=767093
fix up
Only generate crossing events on wl_touch.down for the virtual master
device used for touch events, and only whenever this virtual device
actually moves across surfaces. This behavior resembles better what is
expected in X11, where the pointer is warped to the touch position
on XITouchBegin.
This avoids the double emission of leave events when the pointer
emulating touch is lifted, that crossing event will be instead
generated when/if the focus surface changes.
https://bugzilla.gnome.org/show_bug.cgi?id=766314
The wayland specification for discrete step information for scroll and
other axes reads:
| The discrete value carries the directional information. e.g. a
| value of -2 is two steps towards the negative direction of this axis.
mutter sets a value of 1 for SCROLL_DOWN events and -1 for SCROLL_UP
events.
gdkdevice Wayland backend does the opposite, it translates a positive
discrete value as SCROLL_UP and a negative value as SCROLL_DOWN, which
ends up inverting the scrolling direction.
Fix the logic in gdkdevice Wayland to use a positive value as
SCROLL_DOWN and a negative value as SCROLL_UP so that it matches mutter
and weston logic.
https://bugzilla.gnome.org/show_bug.cgi?id=765907
NoSymbol is not a valid GDK symbol (it only has the concept of
VoidSymbol, for some reason, which is neither the same thing nor
produced by any sane keymap). Passing NoSymbol events through to GTK+
apps is unlikely to produce anything useful.
In particular, this meant VTE would scroll to the end of the buffer when
pressing Fn (required for Page Up/Down on Macs), as it was receiving a
keypress that wasn't a modifeir. This does not happen on X11, as the
KEY_FN keycode is above 255, so does not get sent to clients.
https://bugzilla.gnome.org/show_bug.cgi?id=764825
We don't care about the specific (possibly client-side) window that
requested the focus here, only the toplevel. Fixes mistakenly sent
focus events when the grab happens inside the current focus window.

Always associate a drag context with a GdkDisplay and use that when
getting a cursor for a given action.
If we don't do this, dragging on a window that doesn't use the default
display will make us use cursors from the wrong display.
https://bugzilla.gnome.org/show_bug.cgi?id=765565
The naming of pointers to GdkWaylandDisplay's were inconsistent.
Running the following commands in gtk+/gdk/wayland illustrate the
inconsistency:
$ grep -r '\<display_wayland\>' *.[ch] | wc -l
195
$ grep -r '\<wayland_display\>' *.[ch] | wc -l
81
This patch renames all occurrences of "wayland_display" to
"display_wayland". This is also consistent with naming in the X11
backend. A couple of whitespace changes were done as well in places
where the rename was already done, that added line breaks to long lines
that stood out.
https://bugzilla.gnome.org/show_bug.cgi?id=765474
When synthesizing keyboard repeat, we can potentially drift further from
the mark depending on the timing of the frame callback and how long it
took to deliver the event.
This patch attempts to reduce this by tracking from a stable epoch the
time of our next keyboard repeat.

Windows save in hardware_keycode an information which is not so low

If we get gdk_wayland_seat_flush_frame_event() with no previous event to be
flushed, we fallback into the scroll event checks. However, there's no check
performed there as to whether it really scrolled, so it'd always send a smooth
scroll event with 0/0 deltas in this case.
This should be mostly harmless, but still, we should only end up emitting scroll
events if those really happened.
The frame event is also meant to compress wl_pointer.leave events, at this
point the focus surface will be definitely NULL. In the end, wl_pointer.frame
should flush the last composed event despite the pointer focus.
https://bugzilla.gnome.org/show_bug.cgi?id=765065
On wayland, such axes are per-tool, we must update device capabilities
on the fly as new tools enter proximity, first the slave device so
it matches the current tool, and then the master device so it looks
the same than the current slave device.
Only the management of tablets and tools is added so far. No tablet events
are yet interpreted.
As it's been the tradition in GTK+, erasers are split into their own device,
whereas the rest of the tools are meant to be routed through the
GDK_SOURCE_PEN device. Both pen/eraser devices are slaves to a master
pointer device, separate to wl_pointer's. This is so each tablet can
maintain its own cursor/positioning accounting.
Signed-off-by: Stephen Chandler Paul <thatslyude@gmail.com>
This will enable multiple "pointers" to have separate data here.
Will come out useful when adding support for tablets, as they
will have a separate cursor for all purposes.
Now that GdkWaylandDeviceData is gone, the functions prefixed
"gdk_wayland_device_" and taking a GdkWaylandSeat as first
parameter feel out of place. Renaming those makes it more obvious
that it's seat functions.
https://bugzilla.gnome.org/show_bug.cgi?id=763859
It's the same than gdk_device_get_seat() nowadays. Also, rename the
usages of GdkWaylandDeviceData to GdkWaylandSeat in the functions

key repeat is handled client side, which means stalls in the compositor
dispatching key release events can lead to fictious repeat events.
This commit ties key repeat to a server roundtrip to ensure the client
and server are in sync.
https://bugzilla.gnome.org/show_bug.cgi?id=757942
We don't need the key repeat rate or anything like that when
handling key up events, so do key up events first before querying
for that information.
https://bugzilla.gnome.org/show_bug.cgi?id=757942
deliver_key_event is sometimes called from a timeout handler and
sometimes called directly. We currently erroneously return TRUE
(G_SOURCE_CONTINUE) in the case where it's called directly, but to
no ill effect, since we ignore that return value. In the future,
we're going to need to call it directly in other parts of the code
where the return value would be relevant and handling TRUE, would
require adding redundant code.
Instead, this commit just changes the code to always reset the timer
manually, and never rely on glib's ability to automatically reset
the timer by returning TRUE. This makes the code smaller, too, since
there's less special casing required.

I am testing GTK+ master against mutter 3.19.90, so I'd
like GTK+ to survive even when the compositor does not
support the primary selection interface.
Implement it using the internal copy of the protocol. Otherwise,
we just deal with it the same than clipboard selection, just mapping
it to the PRIMARY atom instead of the CLIPBOARD one.
https://bugzilla.gnome.org/show_bug.cgi?id=762561
If the grab window is destroyed the grab will be implicitly removed,
although we won't get GdkSeat:ungrab called in order to clear our
internal window<->seat relation entirely. Setting a weak ref will
nullify the pointer we keep on the seat to the window, avoiding the
expected crashes.
Due to implicit grabs, we basically can guarantee that the pointer
won't have any buttons pressed at the time of wl_pointer.enter.
Seems like a good place to unset any button modifiers that might
have been left stale by compositor grabs.
And use it to handle kinetic scrolling in the GtkScrolledWindow.
However, dropping the delta check causes the X11-based kinetic
scroll to break since we don't have the stop event here. Correct handling of
xf86-input-libinput-based scroll events is still being discussed.
https://bugzilla.gnome.org/show_bug.cgi?id=756729
This adds support for the new wl_pointer events available in v5.
The wl_pointer.axis_source events can be ignored for the purposes here, the
main reason they exist is so that the combination of axis_source=finger and
axis_stop triggers kinetic scrolling. We don't need to care about the source,
axis_stop is enough for us to tell us when we're scrolling.
The wl_pointer.frame events group events together and is intended as a
mechanism to coalesce events together. This for example allows us to now
send a single GTK scroll event for a diagonal scroll. Previously, the two
wl_pointer.axis events had to be handled separately.
The wl_pointer.axis_discrete event sends mouse wheel clicks where
appropriate, and is translated into up/down/left/right scroll events.
https://bugzilla.gnome.org/show_bug.cgi?id=756729
When a cursor is specified in gdk_seat_grab(), the cursor is reverted as
soon as the pointer enters or leaves another window.
To avoid this issue, store the grab cursor separately, so we force-apply
it in ::set_window_cursor(). Also, unset early the seat info from the
window on gdk_seat_ungrab(), so the next time switch_to_pointer_grab()
happens we end up picking the cursor set for the window underneath the
pointer window.
Based on a patch by Olivier Fourdan <ofourdan@redhat.com>.
https://bugzilla.gnome.org/show_bug.cgi?id=760213
We no longer need a grabbed seat, instead we'll just use the default
seat if this happens, not without first warning and recommending
gdk_seat_grab() for the operation.
https://bugzilla.gnome.org/show_bug.cgi?id=759309
This allows GDK to unset the grab itself. Also, make sure we unset
the "pointer emulating" touch on the device if this is the
pointer emulating sequence.
https://bugzilla.gnome.org/show_bug.cgi?id=759309
GdkWaylandDeviceData conceptually gathers the data that belongs to
a seat, so it's been renamed (although the old typedef stays, plenty
of refactoring is due here...).
The methods in GdkSeatClass have also been implemented, the most
remarkable is ::grab, which ensures the grab is performed on all
the relevant "master" devices.

Instead of having our own copy of the pointer gestures XML file, use
the one installed by wayland-protocols.
Since pointer gestures is an unstable protocol, it went through the
unstable protocol naming convention changes, which is reflected in this
commit.
https://bugzilla.gnome.org/show_bug.cgi?id=758634
After the grab is finished, we would expect an enter event, and
GDK updating internally the cursor for that window and device.
This means there is no need at all to store it separately in the
backend.
As a side effect, animated cursors are now also possible on grab
icons.

If the buffer of a cursor is NULL, for example if its an empty cursor,
just set the cursor surface to NULL as well. Not doing this we'll use
uninitialized hotspot coordinates, dimensions and scales.

This GdkDragContext should be created even if we don't have pointer
capabilities. Make it created on add_seat(), and only set the device
on wl_seat.capabilities, so it can be set to either master pointer.
https://bugzilla.gnome.org/show_bug.cgi?id=741066
Now that we have multiple master pointers, this call may pick the wrong one.
Instead, pick the GdkWaylandDeviceData from the first device, and pick the
master pointer from there.
The common GDK code accounts for "pointer emulating" touch sequences to be
synchronized with the pointer position by the windowing system.
However on Wayland pointer and touch are completely independent, the backend
attempts to implement pointer emulation, but doesn't account for the
possible crossing events happening when the user switches from pointer to
touch or the opposite.
In order to fix this, and to ensure we don't have to interact with the
master pointer (which backs the wl_pointer), separate the touch interface
to have its own master pointer, and ensure crossing events are emitted on
it, so the picture of an "emulated pointer" is complete above the backend.

We were using that range for the extra buttons after left/right/middle,
while this is harmless for clients not handling extra buttons (we
used to translate those button events into scroll events in x11 anyway)
this will be unexpected for clients that do handle additional mouse
buttons themselves (eg. back/forward buttons present in some mice).
In order to remain compatible with X11, those need to be assigned from
button 8 onwards.
Also, include input.h, and stop using magic numbers here.

GDK_NOTIFY_ANCESTOR would happen when the pointer crosses across a direct
parent/child. However nonlinear events are more likely, specially when
the pointer moves across toplevels (either different apps, or menus being
popped up over the pointer position).
This makes popping up comboboxes and other menus that fall over the pointer
position possible. With the previous detail the GtkMenu code misinterpreted
the crossing event, making it think the button release coming right after
should dismiss the popup, which made menus just flash on the screen unless
you kept the button pressed.
