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.
Without this, the back buffers of the wrong size
keep being used, causing flickery misdraws, as
seen when expanding the expander in the popover
in widget-factory.
surface->x/y (and various x,y arguments) should be in the parent
coordinates, so treat it as such. We also keep track of the root coords
as these are needed for popup positioning.
Also, drop the isTemp property server side and the weird initial
placement at (100, 100) in the daemon. We now fully control window
placement from the client instead. If this is not we want we should do
a serious design for that but until then lets do the simplest thing.
In firefox, onload will trigger when the image is loaded, but at
that point it may not be decoded yet so showing it will sometimers
trigger flashes. We use the new decode() feature instead which ensures
both that the image is loaded *and* decoded, thus fixing the flashes.
These fixes were done blindly, to make the ci pass,
and will need review by somebody with access to an
actual win32 system to make sure the surface subtypes
are implemented properly.
There is no shape combining going on anymore, so
call this just gdk_surface_set_input_region, and
remove the offset arguments too. All callers pass
0 anyway.
Update all callers and implementations.
This is not quite right, and only temporary, since
it makes GDK_IS_POPUP (surface) true for every surface.
Eventually, the implementation will be moved to the
backends.
Sprinkle various g_assert() around the code where gcc cannot figure out
on its own that a variable is not NULL and too much refactoring would be
needed to make it do that.
Also fix usage of g_assert_nonnull(x) to use g_assert(x) because the
first is not marked as G_GNUC_NORETURN because of course GTester
supports not aborting on aborts.
Drop the input-mode, since it only makes sense for
floating devices, which we don't have anymore. And renamt
::input-source to ::source, to match the getter.
Update all users.
replace all uses with const char * (non-interned).
Also remove a lot fo juggling from atom to GdkAtom to string and back.
The X Atom hash table is now mapping to (again, non-interned) strings.
We were not properly converting the coordinates we
got to root coordinates. This was showing up as offsets
between the actual drop target and the area where drops
can happen, e.g. when dragging over a stack switcher
to switch pages.
We were forgetting to clean up the ::xevent signal
handler in some error cases. Move the signal connection
later, when we know the drag is going forward, and
use g_signal_connect_object to make sure the signal
handler is not forgotten.
This allows treating drop events like touch events, which GTK groups by
event sequence.
It's a bit ugly that we just case the GdkDrop pointer, but event
sequences are only meant to be unique pointer ids, so it's fine.
When a popup is already showing, and gdk_surface_present_popup() is
called, if the layout didn't change, we're not really interested in
relayouting.
In the future, we'll be able to get notified if position of the popup
would change by some environmental changes, but until then, just don't
support it.
Rearrange a few things, and move some booleans
into the Any struct, by using a bitfield there.
Some more cleanup could be done - the flags field
with its PENDING and FLUSHED members appears
entirely unused. Nobody is setting those flags.
Restructure the getters for event fields to
be more targeted at particular event types.
Update all callers, and replace all direct
event struct access with getters.
As a side-effect, this drops some unused getters.
Make the event translator return a new event, instead of
filling in a half-constructed one.
Update the two implementation in GdkX11Display and
GdkDeviceManagerXI2.
Instead of passing a half-constructed event and expect
it to be filled in, pass the surface as in argument, and
add an out argument for a newly constructed GdkEvent.
Add private API to construct events. This is a step towards
making events readonly, and not objects anymore.
The constructors here are sufficient to convert the Wayland
backend over. More may be added for other backends as needed.
Open issues:
- history
Replace the gdk_surface_move_to_rect() API with a new GdkSurface
method called gdk_surface_present_popup() taking a new GdkPopupLayout
object describing how they should be laid out on screen.
The layout properties provided are the same as the ones used with
gdk_surface_move_to_rect(), except they are now set up using
GdkPopupLayout.
Calling gdk_surface_present_popup() will either show the popup at the
position described using the popup layout object and a new unconstrained
size, or reposition it accordingly.
In some situations, such as when a popup is set to autohide, presenting
may immediately fail, in case the grab was not granted by the display
server.
After a successful present, the result of the layout can be queried
using the following methods:
* gdk_surface_get_position() - to get the position relative to its
parent
* gdk_surface_get_width() - to get the current width
* gdk_surface_get_height() - to get the current height
* gdk_surface_get_rect_anchor() - to get the anchor point on the anchor
rectangle the popup was effectively positioned against given
constraints defined by the environment and the layout rules provided
via GdkPopupLayout.
* gdk_surface_get_surface_anchor() - the same as the one above but for
the surface anchor.
A new signal replaces the old "moved-to-rect" one -
"popup-layout-changed". However, it is only intended to be emitted when
the layout changes implicitly by the windowing system, for example if
the monitor resolution changed, or the parent window moved.
We can map a non-grabbing popup wherever, it's just the grabbing
popup-chain that needs to be ensured not to break any ordering rules.
Fix this by managing two lists; one of open popups, and another for
grabbing ones.
The returned position should be relative to the parent surface, but
GdkSurface::x,y were only managed properly for O-R windows. This makes
it correct for regular windows too.
Now popups surfaces are always created with the parent set, so we don't
need to implement vorious guess work to try to find what the parent
might be. Remove that code and just use GdkSurface::parent which is
where the parent set during construction ends up at.
Add event queues specifically for surface configuration events
(xdg_surface.configure, xdg_toplevel.configure, xdg_popup.configure etc)
so that a configuration can be completed without having side effects on
other surfaces. This will be used to synchronously configure specific
GdkSurfaces, as is needed by the Gtk layout mechanisms.
The freezing is conditioned on various state, so lets make the thawing a
bit more robust. Without this there was a risk that we'd thaw too many
times if there was a frame callback requested while the conditions for
the freezing were not met.
Content providers are meant to be immutable, apart from very special
cases, but in those cases they need to emit
gdk_content_provider_content_changed().
Having a constructor that just uses a get_func invites abuse of this
by not making developers aware of those requirments.
In fact, all users in GTK failed to do this.
Instead, code should use the GtkDragSource::prepare signal to create
content providers when needed.
The same problem exists with gdk_content_provider_new_with_formats(),
but this commit doesn't touch that.
Otherwise the compositor gets all confused when it's trying to make
drag happen but we know it's not going to happen.
After all, we exchange data behind its back, we just need to keep it
informed.
1. GdkDrop does deserialization, so add the deserialize formats
2. If the drop is local, we can copy straight from the drag, so we can
also copy all its formats. This fixes cases where the backend would
drop formats it doesn't support.
For a given OpenGL context, macOS in particular does not support enumeration / detection of OpenGL features that have been promoted to core OpenGL functionality. It is possible other drivers are the same. This change assumes support for GL_ARB_texture_non_power_of_two with OpenGL 2.0+, GL_ARB_texture_rectangle with OpenGL 3.1+ and GL_EXT_framebuffer_blit with OpenGL 3.0+. I failed to find definitive information on whether GL_GREMEDY_frame_terminator has been promoted to OpenGL core, or whether GL_ANGLE_framebuffer_blit or GL_EXT_unpack_subimage have been promoted to core in OpenGL ES. This change results in a significant GtkGLArea performance boost on macOS.
Closes#2428
The function is fundamentally broken for unbounded surfaces.
If a surface is unbounded, we cannot represent this as a
cairo_rectangle_int_t, and using the return value doesn't work because
it's already used for something else.
In GTK3, unbounded surfaces aren't a problem, but GTK4 uses recording
surfaces.
So better remove that function before we keep using it and using it
wrong.
The marks are averaged based on the name, so this makes more sense.
Also rename the map/unmap marks to have the same capitalization as
everything else.
I was getting CI failures like:
../gdk/gdkprofiler.c: In function ‘add_markvf’:
../gdk/gdkprofiler.c:111:3: error: function ‘add_markvf’ might be a candidate for ‘gnu_printf’ format attribute [-Werror=suggest-attribute=format]
This drops the marks for before/after-paint as they are internal
things that very rarely use any time, and also flush/resume-events
as any events reported here will get separate marks so will be easy
to see anyway.
Also, we rename the entire frameclock cycle to "frameclock cycle"
rather than "paint_idle" which is rather cryptic.
These don't take a duration, instead they call g_get_monotonic_time() to
and subtract the start time for it.
Almost all our calls are like this, and this makes the callsites clearer
and avoids inlining the clock call into the call site.
When we use if (GDK_PROFILER_IS_RUNNING) this means we get an
inlined if (FALSE) when the compiler support is not compiled in, which
gets rid of all the related code completely.
We also expand to G_UNLIKELY(gdk_profiler_is_running ()) in the supported
case which might cause somewhat better code generation.
usec is the scale of the monotonic timer which is where we get almost
all the times from. The only actual source of nsec is the opengl
GPU time (but who knows what the actual resulution of that is).
Changing this to usec allows us to get rid of " * 1000" in a *lot* of
places all over the codebase, which are ugly and confusing.
This allows us to avoid hand-rolling g_strdup_printf calls,
but also moves the printf into the called function where
it doesn't bloat the code of the calling function if the profiler
is not running.
All the code in e.g. init_randr15() divides the physical resolutions with
the screen scale, however if we get the screen scale from xsettings
rather than e.g. GDK_SCALE the initial setup is using the wrong value.
So, whenever the screen scale size is changed we need to trigger
a re-read of the randr data
1. Rename the thing
2. Turn it from a signal to a vfunc
3. Pass the GtkCssStyleChange to it
We don't export any public API about the GtkCssStyleChange yet, it's
just a boring opaque struct.
We're not in the business of adding Cairo APIs. That's Cairo's job.
Also, we don't need this API anywhere like the original commit claimed,
so there's no need to make it available in any way.
This reverts commit afa6cc2369.
This was blocking the clean exit from the testdbus shutdown in
the defaultvalues test. The proxy was keeping the connection alive
which blocks g_test_dbus_down().
This adds a GDK_DEBUG=default-settings flag which disables reads
from xsettings and Xft resources, and enables this for the testsuite.
This is one less way to get different testresults depending on the
environment. In particular, it was failing the css tests for me
due to getting the wrong font size because i have a different dpi.
We only have implementations of this on X11 and Win32,
so make it available as backend api there.
Update all callers to use either the backend api, or
just monitor 0.
When a device is added, there are two references to it by the device
manager, the initial one and the one used for the id_table. Removing a
device only removed the reference added by the id_table resulting in the
GdkDevice being leaked.

Copy just enough of libwayland-cursor to make our own
loading. This lets us drop the dependency on libwayland-cursor,
and changes the startup cost for cursor theme loading
from 25ms to 0.1ms.
At the same time, simplify the handling of scaled cursors -
instead of creating an array of theme objects, just make a
single theme object provide all scaled cursor sizes.
Instead of reporting the frame clock phases as defined,
report the duration of the signal emissions, which is more
useful for tracking down what is taking time.
Add marks for when we do commits, swap buffer or
receive frame events. These are the low-level start
and end points of the frame cycle, and it is useful
to see them in the profiler.
According to the ICCCM spec [1], one should subtract the base size from
the window size before checking that the aspect ratio falls in range.
This change fixes shrinking Firefox Picture-in-Picture windows when
running KDE Plasma (with KWin as the window manager).

This is a neverending story. I was seeing problems in tests where
the nested mainloop was picking up unrelated timeouts.
Break down and make this async. This changes the ordering in which
the (de)serializers are registered. If this is causing issues, we
can introduce priorities or something else.
According to XDND "The XdndLeave message cancels the session.",
issue one when cancelling a drag, so the dest side has an opportunity
to forget about the GdkDrop.
The drag source might be cached and held alive, only disposed after
future drag begin operations. Ensure the drag surface gets hidden
properly or might might stay transparent but mapped till then.
We were always adding ASK to the list of possible
actions, and preferring it. This was causing the
ask cursor to show up when both the source and
the target support ASK, even though it is only
meant to happen if you hold the Alt modifier.
Instead, use one of the supported actions as
preferred action.
When creating a new GdkDrop object on drag_enter, take pending
source_actions and action into account. The code to store the
pending actions was already there, they were just not passed
on to the drop object when we create it.
We need to set the drag to NULL in gdk_wayland_drag_drop_done,
otherwise, all future drags will be considered local after the
first local one. Worse, they will also provide the wrong data.
The GdkDrop emit... apis take root coordinates.
That should be changed to surface coordinates,
eventually. For now, make the functions fill
the x, y fields.
Don't store coordinates as shorts. Use doubles,
as everywhere else. Also add x, y in addition
to x_root, y_root, and actually return those
in gdk_event_get_coords.
When a new popup surface is created, it may end up
getting a resume-events signal from its frame clock
without having seen a flush-events first.
Don't unpause events in that case, since it messes
up the displays pause counter.
This was causing criticals with tooltips.
Otherwise the icon "jumps" to the cursor position with its top left when
the animation starts.
This is especially visible if the dragged item is big, like when dragging
mails in Thunderbird.
We use a compilation symbol in our build to allow the inclusion of
specific headers while building GTK, to avoid the need to include only
the global header.
Each namespace has its own compilation symbol because we used to have
different libraries, and strict symbol visibility between libraries;
now that we have a single library, and we can use private symbols across
namespaces while building GTK, we should have a single compilation
symbol, and simplify the build rules.
The existing xdg-shell protocols do not support minimization in a way
that allows us to implement the GdkSurface API; the only minimization
operation does not come with a state notification, nor it comes with
a way to undo itself.
Closes: #67
The "iconified" state is mostly an X11-ism; every other platform calls
this state "minimized" because it may not involve turning a window into
an icon at all.
Using gsettings for this information does not work
in sandboxed scenarios, where settings are per-app.
Since the Wayland protocol provides this information
nowadays, just drop the old code for reading
the gsettings.
The event may end up freed after delivery, ensure to keep a ref in order
to emit the matching emulated crossed event matching a proximity event.
Closes: https://gitlab.gnome.org/GNOME/gtk/issues/2157
The code managing this accounting mixed seat and tablet output lists,
can't bode well. Fixes invalid reads on list elements, as there are
dangling pointers.

This is the Vulkan version of eglSwapBuffersWithDamage(), and
it's always a good idea to limit the number of pixels we're
pushing to the GPU and/or swapping into the display.
This is a requirement for using VK_KHR_incremental_present.
Vulkan Wayland drivers translate the VkPresentRegionsKHR to
wl_surface.damage_buffer(), which a v4-only request.
When calling gdk_wayland_surface_export_handle(), if we pass
some 'user_data' but no 'destroy_func', GTK4 crashes. That's
because in xdg_exported_handle() we are unconditionally calling
destroy_func -- even when it's NULL.
Fix that by checking if there's a destroy function before calling
it.
Fixes https://gitlab.gnome.org/GNOME/gtk/issues/2179
The xdg_output.done event is deprecated in xdg-output v3, so clients
need to rely on the wl_output.done event instead.
However, applying the changes on the fist wl_output.event when using
xdg-output v3 may lead to an incomplete change, as following xdg-output
updates may follow.
Make sure we apply xdg-output events on wl_output.done events with
xdg-output v3.
https://gitlab.gnome.org/GNOME/gtk/issues/2128
Previously, the manufacturer property of the GdkMonitor was NULL,
and having at least PNP id at GdkMonitor.manufacturer makes it
possible to distinguish between different monitors programmatically.
xdg-output v3 marks xdg-output.done as deprecated and compositors are
not required to send that event anymore.
So if the xdg-output version is 3 or higher, simply set the initial
value `xdg_output_done` to TRUE so we don't wait/expect that event
from the compositor.
https://gitlab.gnome.org/GNOME/gtk/issues/2053
Windows/surface's aren't supposed to be explicitly moved by any external
part, so don't provide API for doing so. Usage throughout Gdk is
replaced by the corresponding backend variants.
The generic layer still does the heavy lifting, leaving the backends
more or less just act as thin wrappers, dealing a bit with global
coordinate transformations. The end goal is to remove explicit surface
moving from the generic gdk layer.
To separate how toplevels and popups are configured, a first step is to
introduce a resize-only vfunc for backends to implement. It's meant to
only configure toplevel windows, i.e. popups. Currently it's used for
both types, but introducing the resize-only API is a first step.
Configuration should happen in response to the xdg_surface.configure
event, not in the events that preceeds it. Do this by making all
configured state pending until the committing "configure" event. Also
split up toplevel vs popup configuration in a more clear way.
When unreffing the stream from a different thread, the close function
will schedule its cleanup asynchornously in the main thread.
We need to make sure the stream object stays alive for as long as
that hasn't happened, so ref() it.
Fixes#2003
Instead of the toplevel driving popups, have the popups listen to the
frame clock themselves. Otherwise, if the toplevel for some reason isn't
drawn by the compositor and stops drawing new frames, popups wouldn't
get painted either.
To make a frame clock tick as long as any of the associated surfaces
expect to receive ticks, make the surfaces inhibit freezing the clock,
instead of directly tell the frame clock to freeze itself.
This makes it so that as long as any surface using a certain frame clock
is not frozen (e.g. just received a frame event from the display
server), the frame clock will not be frozen.
With this, the frame clock is initiated as frozen, and won't be thawed
until any surface inhibits freeze. It will be frozen again, when every
surface has that previously inhibited freeze uninhibited freeze.
The xdg_output v2 interface has a `name` property that reflects the
output name coming from the compositor.
This is the closest thing we can get to a connector name.
The migration from GdkScreen's monitor API to GdkMonitor left out a way
to get the connector's name of a monitor.
While there's no real guarantee coming from the underlying graphics
system that the connector's name is stable, some system components may
use it to uniquely identify a monitor until the next plug in/out event.
This gives us marks to track the duration of processing certain types of
GdkEvent. It also provides some basic struct information in cases where
having that information would likely be useful for debugging.
The Wayland backend has a hack to work around
a race with popover mapping: If the surface size
changes before the initial configure, we hide and
show the surface. Unfortunately, the code was doing
this in a way that is externally observable (by
listening for surface state changes), and popovers
were observing it and hiding themselves in response.
Avoid this by not going through the GDK frontend
code for this.
1) In the SetWindowPos() function (and the WINDOWPOS struct) the
"hWndInsertAfter" argument/field means the window that will be
directly above after the change, not the window that will be
directly below. MSDN says "precedes" for SetWindowPos(), but
WINDOWPOS documentation is more precise: this is the window
behind which the affected window will be placed. Apparently,
Z-axis goes back-to-front.
Therefore, logging should be reworded correctly.
2) When we switch away from the application and then switch back
to a transient window, we need to bring up its transient-owner
(and its transient-owner's owner and so forth) as well,
otherwise our transient (modal) window might be transient for
something that might not be visible.
3) When we bring up a window, we should bring all of its children
(popup windows) on top of it.
Because Windows doesn't provide a function to bring one window
on top of the other, we have to work around this by calling
SetWindowPos() twice, swapping the windows between the calls.
Similar to previous removals of g_cclosure_marshal_VOID__VOID we can remove
other marshallers for which are a simple G_TYPE_NONE with single parameter.
In those cases, GLib will setup both a c_marshaller and va_marshaller for
us. Before this commit, we would not get a va_marshaller because the
c_marshaller is set.
Related to GNOME/Initiatives#10
This uses the new sysprof-3 ABI to implement the capture writer. It also
uses the statically linked libsysprof-capture-3.a that is provided with
Sysprof for the capture writing to ensure that we do not leak any symbols
nor depend on any additional libraries.
The GTK_TRACE_FD can be used to pass a FD for tracing into Gtk. Sysprof
uses this when the Gtk instrument is selected for recording.
If we set c_marshaller manually, then g_signal_newv() will not setup a
va_marshaller for us. However, if we provide c_marshaller as NULL, it will
setup both the c_marshaller (to g_cclosure_marshal_VOID__VOID) and
va_marshaller (to g_cclosure_marshal_VOID__VOIDv) for us.
Root coordinates are going away, so this
api does not make sense anymore. Use
gdk_surface_get_device_position instead.
We still keep this as internal api for
root-coordinate using backends.
