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.
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
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.

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.

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. The conversion between formats happens
at GTK level in GtkClipboard or, if GtkClipboard is not used, with
gtk_target_list_add_image_targets() to announce all supported image
formats, and with gtk_selection_data_set_pixbuf() to convert from
any GdkPixbuf formats to the format requested by the selection, and
with gtk_selection_data_get_pixbuf() to convert from the selection
format to GdkPixbuf, if supported.
GDK simply does not play any role in this. 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).
This leverages the normal input module 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 module
loading code, which, not being able to load the desired module
(which is and empty string), falls back to looking at current
keyboard layout.
Paired with the code that signals gtk-im-module change on keyboard layout
switches, this is sufficient to make GTK capable of loading appropriate
input modules at runtime. At least, the kinds of modules that specify
languages for which they are loaded automatically by default, and the
IME module.
Loading other kinds of input modules might still work via specifying
the gtk-im-module setting in gtk ini file, but doing so will likely
make GTK incapable of loading the IME input module 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.
Suggested by Garnacho. Hopefully fixes#1349.

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 359df028be 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.
For building the introspection dumper program on Visual Studio, leave out
the G_LOG_DOMAIN as g-ir-scanner does not like it when it constructs the
compiler command line for Visual Studio.
Also ensure that we are looking for the freshly-built libraries by looking
for the .lib's from the output directories of the Visual Studio project files.
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.
gdk_win32_window_set_transient_for() behaves incorrectly when
called in sequence with the same arguments. This fix ensures it
always operates correctly.
In some cases this function gets called multiple times with the
same arguments, e.g. when tooltips are shown.
See issue #1214
The enum is duplicated in the spec for the manager and the decoration
object. We should be using the right ones. In practice they have the
same value, so this bug didn't cause any issues.
The wl_surface is destroyed and recreated when the window is
mapped/unmapped. As we have a new wl_surface we need to create a new
server_decoration object for that surface.
According to the spec compositors were to assume surfaces are CSD until
told otherwise. This means we need to send
org_kde_kwin_server_decoration_request_mode in both cases.
This fixes libreoffice under kwin, which would remove it's own headers
as per the manager's request but not inform kwin leaving it in the even
more broken state of having none.
Cursor surfaces didn't listen for output scale changes, meaning they
didn't adapt their scale when an output changed scale, which could
happen for example when changing the monitor scale via Settings.
We also need to invalidate the OpenGL/ES window when we resize the
window via a mouse drag operation, so that we don't get glitches in such
situations, because they are not covered in GdkWindow's
impl_class->move_resize().
Make sure that we only force the invalidation when necessary (as it is
expensive), and clean up the gdkevents-win32.c code so that we include
gdkglcontext-win32.h in the right place instead of using an extern, as
we need to invalidate the window accordingly.
We need to force redraws of the whole window when we are using EGL/ANGLE
during maximize, restore and Aerosnap ops so that we do not get glitches
in the resulting window.
This is for adding a EGL-based renderer which is done via the ANGLE
project, which translate EGL calls to Direct3D 9/11. This is done as a
possible solution to issue #105, especially for cases where the needed
full GL extensions to map OpenGL to Direc3D is unavailable or
unreliable, or when the OpenGL implementation from the graphics drivers
are problematic.
To enable this, do the following:
-Build ANGLE and ensure the ANGLE libEGL.dll and libGLESv2.dll are
available. A sufficiently-recent ANGLE is needed for things to
work correctly--note that the copy of ANGLE that is included in
qtbase-5.10.1 is sufficient. ANGLE is licensed under a BSD 3-clause
license. Note also that Visual Studio 2013 or later is required to
build ANGLE from QT-5.10.1, but the 2013-built ANGLE DLLs can work
without without problems for GTK+ that is built with Visual Studio
2008 or later.
-Build libepoxy on Windows with EGL support enabled.
-Define GDK_WIN32_ENABLE_EGL when building gdk-win32.lib when building
with Visual Studio, or pass in --enable-win32-gles during configure
when building with MinGW/mingw-w64.
-Prior to running GTK+ programs, the GDK_GL envvar needs to contain
gles.
Known issues:
-Only OpenGL ES 3 is supported, ANGLE's ES 2 does not support the needed
extensions, notably GL_OES_vertex_array_object, but its ES 3 support is
sufficient.
-There is no autodetection or fallback mechanism to enable using
EGL/Angle automatically yet. There is no plans to do this in this
commit.
Thanks to LRN for pointing out that we should #include
"win32/gdkwin32.h" instead of #include "gdkwin32.h" for gdkgl.c. LRN
also did the autotools portion of this patch.
Further notes about the autotools --enable-win32-gles option, fom LRN:
This adds --enable-win32-gles option, which enables the
code for GLES renderer. This commit also adds tests for WGL and
EGL in epoxy. The absence of WGL is highly unlikely (it's enabled
by default), but checking for EGL when GLES is enabled is necessary,
as EGL is disabled in Windows builds of epoxy by default.
This functionality is similar to Linux's memfd. It creates anonymous shared memory without touching the filesystem, which allows it to work in Capsicum capability mode (sandbox).
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.

There is no reason why we shouldn't pass this flag every time
Z-order changes. We have separate routines that are used to
maintain relative Z-order, so it should be completely OK to
pass SWP_NOOWNERZORDER to let the OS know that it shouldn't try
to maintain relative Z-order of the windows when raising them.
