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.

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.

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.

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.
