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.
Change gdk_surface_get/set_user_data to private
API and rename them to get/set_widget.
Also remove an unused associated function.
The last two places where the surface API is used
are in gtkroot.c and gtkwidget.c. Make them
use the private api.
When the user approaches a tablet tool to the screen we get a proximity-in event
and in this moment we need to check the surface output scale to find the scaling
to be applied to the cursor.
And the same should be done when the tool is detached or the monitors
configuration changes.

The @filename@ directive will use the full path of the file being parsed

the reproducibility of the build by using only the file name.
Some of the flags got lost in the meson transition or were demoted from
error flags to warning flags.
This commit reintroduces them.
It also includes fixes for the code that had warnings with those flags.
The big one being -Wshadow.
Setting it as qdata on the object doesn't save any memory since we use
the user_data as the event target, which every event has set these days.
This way is also faster since just reffing the object doesn't do any
locking.

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.

This makes apps use "Segoe UI 9" by default instead of whatever matches "Sans 10".
It also cleans up the code and uses some new pango API while at it.
This was previously disabled in 9e686d1fb5 because it led to a poor glyph coverage
on certain versions of Windows which don't default to "Segoe UI 9" (Chinese, Korean, ..)
because the font fallback list was missing in pango.
This is about to get fixed in https://gitlab.gnome.org/GNOME/pango/merge_requests/34
so enable it again when we detect a new enough pango version.
(See !436 for the original MR)
GTK widgets expect the scroll deltas to be 1 or -1 and calculate a scroll value from that.
Multiplying the delta by the Windows scroll line setting (which defaults to 3) results
in a much larger delta and vastly different behaviour for running a GTK app on Windows
vs on Linux. For example text view and tree view scroll by 9 lines per scroll wheel tick
per default this way while on Linux it is around 3.
Remove the multiplication for now.
See !426 for the gtk3 MR
Enables hinting, antialiasing and set the subpixel orientation according to the
active clear type setting. This ensures that font rendering with the fontconfig backend
looks similar to the win32 backend, at least with the default system font.

Build the .rc files for Windows so that one can track the version info
more easily for Windows, as well as giving GTK+ apps a default icon.
Also, move back the manifest embedding for the themed Windows print
dialog back into gtk-win32.rc.body.in, so that we just have one way of
embedding this manifest file, making things easier for ourselves, as
this is supported in the later Visual Studio compilers as well, which is
2013 and later.
As per the spec:
> The back buffer can
> either be reported as invalid (has an age of 0) or it may be
> reported to contain the contents from n frames prior to the
> current frame.
So a buffer age of 1 means that the buffer was used in the last frame.
We were handling buffer_age==1 the same as buffer_age==0, i.e. we
returned the full damage for the surface.

When we decide to fall back because the settings portal
is not present, adhere to that decision elsewhere. And
treat the fontconfig-timestamp like the other special-cased
settings, with G_TYPE_NONE.
Under Wayland, we are currently directly using GSettings
for desktop settings. But in a sandbox, we may not have
access to dconf, so this may fail. Use the new settings
portal instead.
As GSettings now supports session-specific defaults, GNOME Classic
no longer uses a separate schema and the decoration layout is always
determined by the regular schema.
This essentially reverts commit add67b516c (although the code was
moved since then).

By returning a default surface. The situation where there's no
currentContext arises when GtkCSS is trying to determine the
layout sizes so no actual display is necessary.
Closes: #1411
Do not lie to W32 about the formats that we provide or accept.
Originally the logic behind such lies was that GdkPixbuf allows us to
convert any supported image to BMP or PNG, and therefore we should
announce that we always provide/accept BMP and PNG along with other
formats.
But that's not how it works. GDK has built-in serializers and
deserializers for all pixbuf formats (where it just invokes GdkPixbuf
API) and will use them automatically to read or write GdkTexture
objects (internally wrapping GdkPixbuf objects where necessary). The
encoding and decoding of images is handled
by GdkContent(De)Serializers, backend has nothing to do with it.
Therefore W32 GDK backend should only offer formats that it can
actually do conversion for by itself (such as image/bmp <-> CF_DIB,
or text/uri-list <-> CFSTR_SHELLIDLIST).
Instead we just cache the monitor number and get
out of it the nsscreen when it is needed. This is
a requirement since it nsscreen it is not supposed
to be cached.
Fixes: https://gitlab.gnome.org/GNOME/gtk/issues/1312
This leverages the normal input context switching mechanism in GTK
by making it think that the gtk-im-module setting changed.
The backend returns gtk-im-module value as "ime" if W32
IME API says that an IME is in use. Otherwise it returns
and empty string - this still triggers an input context
switching code, which, not being able to create the desired context
(which is and empty string), falls back to looking at current
keyboard layout (currently that code is still a FIXME).
Paired with the code that signals gtk-im-module change on keyboard layout
switches, this is sufficient to make GTK capable of switching to
the appropriate IM context at runtime. At least, the kinds of context
that specify languages for which they are used automatically by default
(once locale matching is implemented), and the IME context.
Loading other kinds of IM context might still work via specifying
the gtk-im-module setting in gtk ini file, but doing so will likely
make GTK incapable of using the IME context that is used
for Korean, Chinese and Japanese (and some other languages).
Until someone figures out a way to actually change gtk-im-module
setting on Windows at runtime with meaningful values, the behaviour
introduced by this commit seems like a sufficient workaround.
Commit 359df028be changed the
code to send GDK_SCROLL_SMOOTH with deltas instead of
GDK_SCROLL_(UP|DOWN|LEFT|RIGHT).
Windows defines deltas inversed for vertical direction
(positive values mean the wheel was turned forward)
but not for horizontal direction
(positive values mean the wheel was turned towards the right).
This commit fixes behavior as both axes were inverted previously.
Commit d64467b334 changed the
code to send GDK_SCROLL_SMOOTH with deltas instead of
GDK_SCROLL_(UP|DOWN|LEFT|RIGHT). Change it again, to send
both the GDK_SCROLL_SMOOTH and the GDK_SCROLL_(UP|DOWN|LEFT|RIGHT)
event separately (with the discrete event marked as emulated),
as this is what other backends (such as wayland) do.
Let's just use the fact that a window was mapped as a subsurface to
remap it above another transient parent instead of relying on the more
complicated 'should-map-as-subsurface' helper function.
Set delta_x or delta_y for GdkScrollEvent.
HIWORD (wParam) in WM_MOUSE(H)WHEEL is the scroll delta.
A delta value of WHEEL_DELTA (which is 120) means scrolling
one full unit of something (for example, a line).
The delta should also be multiplied by the value that the
SystemParametersInfo (SPI_GETWHEELSCROLL(LINES|CHARS), 0, &value, 0)
call gives back, unless it gives back 0xffffffff, in which case
it indicates that scrolling is page- or screen-based, not line-based
(GDK doesn't support that at the moment).
Also, all deltas should be inverted, since MS sends negative deltas
when scrolling down (rotating the wheel back, in the direction of
the user).
With deltas set the mode should be set to GDK_SCROLL_SMOOTH.
Fixes issue 1263.
GLib master propagates argument types in g_clear_pointer(), which causes
the usual function pointer casts to GDestroyNotify to trip compiler
warnings. Additionally, this commit changes some cleanup functions where
appropriate (wl_data_source_destroy ->
gtk_primary_selection_source_destroy for struct
gtk_primary_selection_source).
GtkEntryCompletion can rapidly release and claim ownership of the
primary selection. This generates multiple XFixesSelectionNotify events,
first stating that no one owns the selection, then another stating that
we own the selection. The notification that no one owns the selection
causes GtkEntryCompletion to deselect the text, breaking inline
autocompletion.
This fixes it by ignoring any XFixesSelectionNotify with a timestamp
earlier than our clipboard timestamp.
