There is no need for popups to connect to the frame
clock to pause and unpause events on the display -
the toplevel already does it.
And don't connect to paint either - handle paint
on popups recursively.
Somewhat change the order of initialization (to be closer
to what Wayland backend does).
Also remove the wrapper field that is no longer needed -
it used to hold a pointer to the main GdkWindow instance,
which wrapped GdkWin32ImplWindow. Since impls are gone,
nothing is wrapping anything anymore.
Fix a substitution error, where wrong pointer was added
to the hash table. Added a comment to ensure that future readers
(including myself) won't be confused by the fact that we're
inserting a pointer instead of the handle itself.
Since we are now sharing frame clocks with multiple
surfaces, we can no longer dispose them unconditionally
when a surface goes away. Only do it if we are a
toplevel (without parent).
This was showing up as criticals on exit when opening
and closing any popover in widget factory.
Now that popups share the frame clock of their
parent, we have to be much more careful about
freezing the clock, since that may stop updates
for another surface.
This commit makes two changes that make the
X11 handling of the frame clock more similar
to the Wayland backend:
- Use gdk_surface_freeze_updates instead of
gdk_surface_freeze_toplevel_updates to avoid
affecting the frame clock
- Bail out early in before_paint/after_paint
if the surface is frozen, to avoid affecting
the frame clock
Together, these two make the X11 popup surface
type work without freezing updates for the toplevel.
With separate clocks, the phases are not coordinated,
which messes with GTKs size allocation machinery treating
the entire widget tree as a whole, and causes us to
run into assertion where popups get drawn before they
are allocated.
This api is meant to mimic xdg-popover.grab - we
show the surface, and dismiss it when we get events
on other surfaces. For foreign surfaces, the compositor
handles that for us; for our own, we check outselves
before delivering events to GTK.
Make them use o-r windows, and move
with their parent.
We do a sort-of ok job on stacking order
here - whenever the parent window gets a
ConfigureNotify, we just restack all popups
directly on top of their parent. This is good
enough to keep popups on top of their parent
while we drag it around, and it gets the popup
to disappear when raising another window on
top of the parent.
Store popup parents separately from transient-for
parents, since these are separate concepts with
different behaviors. And we need the parent in
the frontend, so we can use it in the fallback
move-to-rect implementation.
We don't need the complicated wrapper system anymore,
since client-side windows are gone. This commit moves
all the vfuncs to GtkSurfaceClass, and changes the
backends to just derive their surface implementation
from GdkSurface.
We want to use a gdk_surface_new_popup for popups,
and align the constructor names with the surface
types, so rename
gdk_surface_new_popup -> gdk_surface_new_temp
gdk_surface_new_popup_full -> gdk_surface_new_popup
The temp surface type will disappear eventually.
All the information in it is already contained
in the surface object we pass along, and none
of the backend implementations were using the
attributes at all.
We are not creating such surfaces anymore, and
they were only ever meaningfully implemented
on X11. Drop the concept, and the api for determining
if a surface is input-only.
We still need to keep the vfunc around, since the
fallback implementation of gdk_display_get_monitor_at_surface
uses it. So, a GDK backend must either have root coordinates
or always return a monitor from monitor_at_surface.
We still need to keep the vfunc around, since the
fallback implementation for move_to_rect uses it.
So, a GDK backend must either have root coordinates
or implement move_to_rect.
Start by adding a constructor. We have to call it
gdk_surface_new_popup_full for now, since gdk_surface_new_popup
is taken. This may be reshuffled later.
The “xdg-output” protocol provides clients with the outputs size and
position in compositor coordinates, and does not provide the output
scale which is already provided by the core “wl_output” protocol.
So when receiving the wl_output scale event, we should update the scale
regardless of “xdg-output” support, otherwise the scale will remain to
its default value of 1 and the surface will be scaled up by the
compositor to match the actual output scale, which causes blurry fonts
and widgets.

The change to keep some server resources around
until destroy was causing us to not recreate
the right things when a surface is hidden and
then shown again. Make sure to recreate everything.
The Wayland backend was dropping _all_ serverside
resources on hide, which is too early e.g. for
GtkGLArea which wants to use egl resources to
unload textures on unrealize.
Closes: https://gitlab.gnome.org/GNOME/gtk/issues/1485
We need to store the region *before* adding our own damage area, because
we want to only store the changes of this frame, not the whole history.
So do it in the same place Vulkan does it.
Fixes#1900
We were adding incomplete frame timings to the
profile, which lead to occasional nonsense
numbers. Instead, only add timings to the profile
once we marked them as complete. This also
gives us an opportunity to add the presentation
time as a marker.
Besides requiring it at build time, require that the server the client
is running against exposes the XInput2 protocol. We no longer fallback
on a device manager for core events.
XInput2 is more than a decade old already, and the input improvements
there (and in every other backend really) make it untenable to have
support for X11 core input events dragging things behind.
GdkSurface::set_startup_id() is NULL on Win32 and would cause a segfault
if called.
While the documentation of the main caller of set_startup_id(),
gtk_window_set_startup_id(), mentions that it's not implemented on
Windows it can still be automatically called via Glade and simply doing
nothing on Win32 is going to be less disruptive than a segfault.
If SYSPROF_TRACE_FD is set in the environment,
interpret it as an fd to write profiling data
to.
If GTK_TRACE is set, write profiling data
to a file with name gtk.$PID.syscap.
This is writing data in the capture format of sysprof,
using the SpCaptureWriter. For now, this is using a
vendored copy of libsysprof. Eventually, we want to
use the static library that sysprof provides.
apis that takes multiple display-relative objects
should make sure that they are all from the same
display, or hard-to-track-down badness will happen
later on.
Add such a check for the surface and device arguments
of gdk_seat_grab. This helped in tracking down
critical warnings from combo boxes in the inspector.
Now that GdkSurface has properties, it makes
sense to turn the frame clock into one too.
This will make it easier to reshuffle some
of the surface constructors later.
Make find_grab_input_seat return a GdkWaylandSeat
instead of a struct wl_seat, so we can use it and
avoid calling gdk_display_get_default_seat when
we need to get a serial later.
Save the information whether the cursor in use is the default one, and
don't create a new cursor object in that case.
We previously created a new cursor object every frame just to compare it
to the current cursor in use and then throw it away.
The skip-taskbar, skip-pager and urgency hints were
only ever implemented for X11, and are not very useful
with modern desktops. Relegate the functionality to
x11 backend api, and drop the GtkWindow api.
And update the surface accordingly (eg. scale on hidpi). The mechanism
that did that for wl_pointer has been made generic so it can be shared
with tablets too.
Closes: https://gitlab.gnome.org/GNOME/gtk/issues/1675
_gdk_wayland_cursor_get_buffer was not initializing
its out variables in the 'not found' case. This
was showing up in protocol traces as garbage hotspots
being sent to the compositor.
Closes: https://gitlab.gnome.org/GNOME/gtk/issues/1328
Previously, the GDK backend for Wayland would deduce the logical size
of the monitors from the wl_output size and scale.
With the addition of fractional scaling which advertises a larger scale
value and then scale down the client surface, the computed logical size
of the monitors in GDK would be wrong and confuse applications which
insist on using the monitor size and position (like Firefox).
The xdg-output protocol aims at describing outputs in a way which is more
in line with the concept of an output on desktop oriented systems by
presenting the outputs using their logical size and position appropriately
transformed.
Add support for the optional xdg-output protocol so that the size and
position of the monitors as reported by GDK is correct even when using
fractional scaling.

This function is a (private) function to parse a GdkRGBA accoridng to
the CSS specs. We should probably use it for gdk_rgba_parse(), but that
would change the syntax we accept there...
This also introduces a dependency of libgdk on libgtkcss.
So far, no users for this function exist.
This library is meant to be the new CSS library that gets used from GDK,
GSK and GTK for string printing and parsing.
As a first step, move GtkCssProviderError into it.
While doing so, split it into GtkCssParserError (for critical problems)
and GtkCssParserWarning (for non-critical problems).
Since commit 3b2f9395, the frame time may be set into the future, so
only ensure monotonicity, and don't store the offset. This prevents the
frame time from becoming out of sync with g_get_monotonic_time().
Fixes#1612
We preiously did not apply the resizes and moves as they were previously
only done in the Cairo drawing context on Win32. Fix this by applying
this too in the GL drawing context.
Make gdk_win32_surface_get_queued_window_rect() and
gdk_win32_surface_apply_queued_move_resize() not static functions, as we
want to use them in gdkglcontext-win32.c, to fix resizing and moving.
As in commit d45996c, the x and y coordinates passed into begin_drag and
begin_move are no longer root coordinates but are now surface
coordinates.
Use the x and y surface coordinates to acquire the root x and y
coordinates so that resizing and moving can work as expected.
I've come to the conclusion that we should keep
this state, since not all backends support per-edge
information. Updated the docs to explain how the
tiled state relates to the per-edge states.
This is nice when you want to make a "screenshot" by using save-as.
Its not going to perform as well though, so you have to enable it
by adding ?datauri to the url
This is not ideal because we report the time of a full roundtrip, rather
than the presentation time, but its better than nothing, and i'm not sure
how the browser time should be reconciled.
This is a very old X session management thing, and you
will be hard-pressed to find a session manager that can
make use of it, and even harder-pressed to find apps
using it to their advantage.
Change the all the begin_drag and begin_move apis in
GdkSurface and GtkWindow to expect surface coordinates.
Update the x11 implementation to translate to root
coordinates where it matters. Wayland is ignoring the
coordinates anyway.
When sending render nodes from the client to the daemon we add an id,
and whenever we're about to re-send the entire tree node we instead
send the old id. We track all the nodes for the previous frame
of the surface this way.
Having the id on the daemon side will allow us do to much better deltas.
We want to delay some rendering, and to make that safe we need to correctly
refcount the use of blob uris for the textures so that we don't unref
it while something is scheduled to use it.
ImmIsIME() doesn't work (always returns TRUE) since Vista.
Use ITfActiveLanguageProfileNotifySink to detect TSF changes,
which are equal to IME changes for us.
Also make sure that IMMultiContext re-loads the IM when keyboard layout
changes, otherwise there's a subtle bug that could happen:
* Run GTK application with non-IME layout (US, for example)
* Focus on an editable widget (GtkEntry, for example)
* IM Context is initialized to use the simple IM
* Switch to an IME layout (such as Korean)
* Start typing
* Since IME module is not loaded yet, keypresses are handled
by a default MS IME handler
* Once IME commits a character, GDK will get a WM_KEYDOWN,
which will trigger a GdkKeyEvent, which will be handled by
an event filter in IM Context, which will finally re-evaluate
its status and load IME, and only after that GTK will get
to handle IME by itself - but by that point input would
already be broken.
To avoid this we can emit a dummy event (with Void keyval),
which will cause IM Context to load the appropriate module
immediately.
This is named gdkconstructor.h to avoid any possible conflicts. This fixes
the current usages of G_HAS_CONSTRUCTORS, as that header is not installed
by glib.
