The handling is done similar to drag targets.
Note that dragging is a modal action on macos: no events
are sent to the main window. This could cause trouble when
we finish the drag, and not finish the gesture in GTK.
This will make it easier to reuse from drag integration so that we don't
require clipboards for everything.
We will need to subclass the pasteboard provider twice, however, both
for clipboard and dragging.
Clang was complaining that we never use the
value stored in mime_type. Just don't store it,
we are only interested in the side-effect
(interning the string).
We have various layers where we store the startup ID for a request,
since this API does not have a GdkToplevel that we can refer about
for the Wayland platform, this is the most obvious candidate to
start untangling these various layers.
Deprecate this call, it is already unused in the gtk/ side.
In the way towards deprecating gdk_display_notify_startup_complete(),
make gdk_toplevel_set_startup_id() on X11 perform this piece of messaging
itself. It should be harmless that the message is emitted twice, if
callers do still use that API.
This call has everything to perform activation as specified by the
xdg_activation protocol, notably a surface to activate as opposed to
gdk_display_notify_startup_complete().
Make activation happen here, so that the surface gets activated when
its gets a startup ID assigned.
The owner_events=TRUE grab makes GDK on X11 see events happening
outside every client window as received on the grab window.
Additionally check that the pointer is inside the grab window
(i.e. it received GDK_CROSSING_NORMAL crossing events for the
core pointer) in order to handle clicks happening outside client
windows.
These new paths are expected to be a no-op on Wayland, and to
also work for touchscreen input on X11, due to emulated pointer
events.
Try to get a native file:// URI instead of any other GVFS
scheme, for interoperability with apps only handling file:// URIs.
This is what GTK3 Nautilus and Thunar do, so apps should be tuned
for this behavior.

A Drag surface does not have a parent surface. Therefore, if we initialize
it with one, it's inheriting the frame clock from the parent, but the
drag surface is not linked to the parent. Once the drag surface is destroyed,
it's disposing the frame clock, which results in a "frozen" application.
This is an extra safeguard that avoids grabbing resources longer than
nessecary. It also ensures the resource is removed from the drag,
so it is not freed again.
Currently, the GdkSurfaceX11 implementation relies that the upper
layers hid the surface before destruction, and that no
GdkSurfaceClass.compute_resize happened between them. If these
circumstances happened, there would be a compute_size timeout left
dangling after the surface got destroyed, poking at incorrect data
later on. Something that looks like this was reported in the
recent mutter-x11-frames "SSD frames server":

It perhaps makes sense to warn in these situations, but either way
it sounds like gdk_surface_x11_finalize() could enforce the correct
behavior by ensuring there is no dangling timeouts/data. This commit
does that.
The argument to xdg_activation_token_v1_set_surface is documented to be the
surface requesting the activation, not the surface to be activated, which is
given later when calling xdg_activation_v1_activate.
(c.f. 36cee4bdbc)
Use the same logic as in gdk_wayland_app_launch_context_get_startup_notify_id,
i.e. if we have a surface with focus, set that, otherwise set NULL.
This fixes requesting urgent/focus on wlroots (compositors like Sway, etc.),
which was blocked as the surface requesting the activation didn't have focus.

By using wl_output_release(), GDK lets the compositor to clean up the
output global more nicely.
For example, currently, most compositors remove the global and then
destroy it later after N seconds expire. With this, the compositor could
experiment with destroying the output global once all its resources are
destroyed.
this is to prevent gdk from causing a segfault, when getting event axes
for events that don't have them (i.e. attempting to get pressure from a
mice input device).
GDK_TOUCH_END deserves the same treatment than GDK_BUTTON_RELEASE, since it's
subject to the same circumstances (popping up a menu on long press would be
immediately dismissed on release if we handled them there). Ideally, we would
want to match releases that we obtained a press for while grabbed, but as
the popup is also dismissed on GDK_BUTTON_PRESS/GDK_TOUCH_BEGIN, there's no
use for this tracking.
And GDK_TOUCH_CANCEL sounds weird as a reason to dismiss popups, just like
crossing events would.

clang complained that we may end up jumping
to the cleanup code without initializing data
in the jpeg code. Always initialize data to
NULL to prevent that eventuality.
GTK knows when a surface is modally blocked and automatically drops
button press and release events, so do not block input in advance
from WM_MOUSEACTIVATE.
This is largely adapted from commit 83027c68f1 ("11: Implement
inhibit_system_shortcuts API"), with similar rationale:
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.
Note that Windows has low-level keyboard hooks that could help achieve
the expected behaviour. This is implemented by spice-gtk & gtk-vnc for
example, but correctness isn't obvious. I left a TODO comment.
This patch helps implementing remote desktop widgets with GTK4, since
currently on win32 backend Alt-Tab and such are always left to the
system unless there is keyboard grab (which can't be requested by the
client API anymore, afaict).

There's 2 things broken here:
- The mask was calculated on top of the GDK button (i.e. skipping
4-7 buttons), so GDK_BUTTON4_MASK and GDK_BUTTON5_MASK were not
assigned. This is now calculated on the (continuous) BTN_ evcodes
so it is guaranteed that the next 2 physical buttons (i.e.
back/forward) get these two places in the mask assigned.
- Furthermore, these buttons would be pushed to places in the
modifier mask that they didn't belong to. It is now checked hard
that only the first 5 buttons enable a modifier flag.
Overall, this ensures that no event masks with bonkers values are
forwarded, and that no stale implicit grabs are left after additional
buttons are pressed.
Closes: https://gitlab.gnome.org/GNOME/gtk/-/issues/5301
This makes GtkSettings values on X11 match what we get on
other backends.
Reporting size settings in logical pixels (i.e for scale
== 1) is useful for properly supporting mixed-DPI setups.
As X11 doesn't support mixed-DPI setups anyway, XSettings
doesn't bother providing logical values. Thus we scale
from physical to logical values ourselves.

When getting the serial for primary/clipboard selections we used a
function that largely relied on a GdkEvent being passed. We have
another available function that looks up the most recent serial
given the ongoing touch/tablet input as well.
This is the second best, compared to actually knowing the
input/device from the event that was received by the UI an triggered
the clipboard operation, and is already in use in other places
(e.g. window dragging). It is valid for these situations too.

Use newlines rather than spaces to separate file paths (or uri's)

As documented on MSDN:
> Unlike the WM_LBUTTONUP, WM_MBUTTONUP, and WM_RBUTTONUP messages, an
> application should return TRUE from this message if it processes it.
Empty/zero bounds are sent by the Wayland compositor if there are no
valid bounds to report, e.g. if there are no connected monitors. Report
this to GTK, which uses this to clamp calculated sizes, as INT_MAX, so
that clamping isn't done until there are actual valid bounds to clamp
to.
This fixes clients sometimes shrinking to their minimum size during
hotplugs or after having suspended the session.
We shouldn't assume there is always a monitor to derive bounds from.
If there is no monitor, pass empty bounds, as this matches what
xdg_toplevel.configure_bounds do in this case.
GTK4 gdk/broadway: correct gdk_broadway_device_query_state() to return pointer coordinates relative to the upper left corner of surface
See merge request GNOME/gtk!5053
As far as I'm aware, these only exist with `gdk_wayland_surface_` names
for historical reasons, before these types were split.
This way, those functions will be able to access members of the
`GdkWaylandToplevel` struct. And it just saves a few lines of code.
There is nothing particularly specific to drawables
in there (and we don't have that concept anymore),
so just name the source file to match the header.
Easier for everybody.
Move the autocleanup declarations into their
respective headers.
While we are at it, correct the autocleanup
declaration for GdkEvent to use gdk_event_unref,
not g_object_unref. Oops
Introduce GDK_DISPLAY_DEBUG() and GDK_DEBUG() and
the helper function gdk_debug_message(). This is
meant to clean up the mess of our current debug
statements which wildly mix g_message, g_print
and g_printerr.
The X11 backend can mark modifiers like Shift as consumed even if they
aren't actually active, which seems to be something to do with making
shortcuts like `<Control><Shift>plus` and `<Control>plus` work as
intended regardless of whether the plus symbol is obtained by pressing
Shift and a key (like `+/=` on American, British or French keyboards)
or not (like `*/+` on German keyboards).
However, this can go badly wrong when the modifier is *not* pressed.
For example, terminals normally have separate bindings for `<Control>c`
(send SIGINT) and `<Control><Shift>c` (copy). If we disregard the
consumed modifiers completely, when the X11 backend marks Shift as
consumed, pressing Ctrl+c would send SIGINT *and* copy to the clipboard,
which is not what was intended.
By masking out the members of `consumed` that are not in `state`, we
get the same interpretation for X11 and Wayland, and ensure that
keyboard shortcuts that explicitly mention Shift can only be triggered
while holding Shift. It continues to be possible to trigger keyboard
shortcuts that do not explicitly mention Shift (such as `<Control>plus`)
while holding Shift, if the backend reports Shift as having been
consumed in order to generate the plus keysym.

Right now we only support system DPI awareness in GTK4. In that case
it makes sense to scale text with the DPI of the primary monitor, like
done in GTK3.
We plan to land support for proper fractional scaling in Gdk/Win32, so

i.e. for text magnification, as an a11y feature.

Starting with the Wayland protocol wl_pointer >= 8, discrete axis
events have been deprecated in favour of high-resolution scroll event.
Add a listener for high-resolution scroll events and, for backwards
compatibility, handle discrete events as discrete*120.
Instead of calculating the discrete scroll deltas in
GtkEventControllerScroll, move that code to the event constructor and
access the precalculated values using gdk_scroll_event_get_deltas.
Refactor, no functional changes.
Starting with Linux Kernel v5.0 two new axes are available for
mice that support high-resolution wheel scrolling: REL_WHEEL_HI_RES and
REL_HWHEEL_HI_RES.
Both axes send data in fractions of 120 where each multiple of 120
amounts to one logical scroll event. Fractions of 120 indicate a wheel
movement less than one detent.
The 120 magic number is a copy of the Windows API, so this new
constructor can be used both in Linux >= 5.0 and Windows >= Vista.
Add missing #define g_memdup2() for gdksurface-broadway.c in case of enabled
broadway-backend as used otherwise.
Copy static would_drop() replacement for g_log_writer_default_would_drop()
from gtk-builder-tool.c to gtk-reftest.c
Even though the argument is non-nullable, GTK sometimes incurs in that
by itself by destroying the surface while the event is in flight. This
is the case of popping down a GtkDropdown. When this happens we simply
ignore the crossing event, but we should let it through instead, the
compositor did not send it in vain and we possibly still have pointer
state to undo.
Drop the surface checks, so that the event is propagated along GTK.
Following what was done for pinch/swipe events, give hold gestures their
own distinct sequence as well. Without this it was NULL, which was already
distinct to other touchpad gestures.
If we get an invalid TARGETS reply, we might not have a valid 'type',
which ends up as NULL and segs in the g_str_equal.
(This is probably fallout from my fix 506566b6a4, which I still
can't reproduce reliably, so the last one just moved the seg a bit
further along, and we still don't know who is sending a bad TARGETS).
This corresponds to:

C API users can keep dealing with the implicit equivalence of
GdkFileList and GSList, but language bindings have no idea that one type
is another, and none of them exposes GSList as a type anyway, so they
will need a way to construct a GdkFileList.
Instead of making GdkFileList mutable, and re-implement GSList, we only
provide a constructors pair that lets you create a GdkFileList from a
linked list or from an array.
DnD under Windows needed 3 fixes to work with Gtk.DropTarget.
1. The droptarget_w32format_contentformat_map list never gets
filled so the gdk_win32_drop_read_async throws
"No compatible transfer format found".
This is an easy fix and done the same way in the win32 clipboard code.
2. After a drop no gdk_drop_emit_leave_event gets emitted.
This causes a second drop to trigger a bunch of assertion
'self->drop == drop' failed because the first drop is still active.
This is also an easy fix and done the same way by the macos backend.
3. Handling gdk_drop_status/gdk_drop_get_actions interaction.
In gtk_drop_target_do_drop the code
```gdk_drop_finish (self->drop, gdk_drop_get_actions (self->drop));```
calls the finish operation with the actions of the drop which triggers
```g_return_if_fail (gdk_drag_action_is_unique (action));```
in gdk_drop_finish. The code assumes that GdkDrop::actions gets
narrowed down by calling gdk_drop_status. This is hard to assure
because at the same time gdk_drop_get_actions is used by
gtk_drop_target_accept to figure out if a drag is accepted.
GdkDrop::actions serves a double purpose here as the supported source
actions and the currently agreed on action. Both the x11 and the
wayland backend get this wrong somewhat too. Under wayland/x11 when
a drag coming from a source that supports both MOVE and COPY is
first hovering a drop target that only supports COPY it is afterwards
no longer accepted by other drop targets only accepting MOVE.
Under x11 this is permanent for this drag but with wayland the drag
recovers when hovering other widgets. The win32 backend now sets the
supported source actions before any enter/move/drop and narrows them
down in gdk_win32_drop_status.
The patch only touches the win32 backend and fixes all three issues,
for me restoring DnD under windows.
Closes#4498

The XDND suggested action is a relic from when the source would control
the action for a drop. With the new GtkDropTarget the target decides
the action (not the source). That means the all of the returned
results from the ::enter and ::motion handlers will be unexpectely
ignored. Prefer to use the preferred action over the x11 suggested action.

gdk_x11_drop_update_actions() sets actions to

If xdnd_have_actions is true use xdnd_actions.
Don't return to the main loop, instead force a run of the paint idle.
The paint idle will know to skip all the phases that aren't requested.
This is critically important becuase gdksurface.c assumes the
FLUSH_EVENTS and RESUME_EVENTS phases are matched, and we cannot
guarantee that if we return to the main loop and let various reentrant
code change the frame clock state.
This would lead to bugs with events being paused and never unpaused
again or even crashes.

If we take the early return we don't unscale this at the bottom of the

This bug also affects GTK3 (I noticed this running Firefox tests on X).
The GdkToplevelSize struct already has the concept of "bounds", which
means the largest size a window should reasonably have. It's practically
the equivalent of the monitor the window is intended to be mapped on,
with the "struts" (e.g. panels) cut out. It's used by GTK to use this
information to calculate a default window size that is "lagom" (swedish;
not too large, not too small).
Simplify the API to just return the requirements that the user
has asked for. The rest of the code was undocumented and previously
used as a buggy source for a default value from internal code.
Since the buggy code is now fixed, remove all unnecessary cruft.
There are two reasons for this:
* First, the refactored realize code now makes sure that no
context with unsupported version is ever created.
* Second, this code could bump into false possitives and negatives, since
the user is not requested, nor expected to set_required_version
in any specific order relative to set_allowed_apis. Therefore,
some version could be rejected or accepted based on a set of
allowed apis that the user has not yet correctly configured.
Mimic the behavior of the egl context creation by stablishing
some sane logic for the api and version used. Split the decision
of the type of context (api, legacy) and the creation of a context
of a certain version and all its properties.
By setting and then getting the required version in a context, the code
was not respecting user requirements. Instead, simply get the requested
version by the user clipped by the requirements (display version)
It is useful for backends to get user set preferences while
ensuring the correctness of the result, which will be always
greater or equal than the minimum version provided
Add "stylus" to the list of substrings in a device name that cause it to be recognized

GDK_SOURCE_TOUCHSCREEN instead.

When loading cursors at scale, we expect the
cursor images to have a size of scale * size.
If we don't find such images, load them at their

Without this, cursors will appear in unexpected

On Wayland it is a protocol violation to upload buffers with
dimensions that are not an integer multiple of the buffer scale.
Until recently, Mutter did not enforce this. When it started
doing so, some users started seeing crashes in GTK apps because the
cursor theme ended up with e.g. a 15x16 pixel image at scale of 2.
Add a small sanity check for this case.
Not updating shadow size unconditionally would lead to shadow size not
being set on map, which would lead mutter to think that we are a Window
without extents and then become confused when we suddenly set some.

like GTK3.

Previously, there was an issue with glitching after showing/hiding a
popover that was not also destroyed. This was due to the popover having
an update_freeze_count of zero after hiding the surface.
That resulted in it's toplevel continuously dropping frames such as during
high-frame-rate scrolling in textviews. This problem is much more visible
on high-frame-rate displays such as 120hz/144hz.
With this commit, we freeze the frame clock of the popup until it is
mapped again.
Since GdkTimeCoord stores only axis values, prior to this change,
if a device didn't report GDK_AXIS_X or GDK_AXIS_Y, the history
attached to merged motion events wouldn't contain any positional
information.
Commit 6012276093 already addressed
this issue for devices without tools by storing the event position
in GdkTimeCoord using GDK_AXIS_X and GDK_AXIS_Y and augmenting the
GdkTimeCoord's axis bitmask accordingly.
This change generalizes that workaround to all devices. Note that
if a device DOES report values for GDK_AXIS_X and GDK_AXIS_Y, those
values won't be overwritten.

before calling gdk_clipboard_claim_remote(), which expects it to be not NULL,
otherwise we face a warning from that funtion and the subsequent
g_object_unref().
This at least partially fixes issue #4796.
WebKit's GTK 4 port can give us textures with an internal format of
GL_RGBA with GL_UNSIGNED_NORMALIZED and a bit-depth of 8. This fixes
warnings for every GdkGLTexture created/delivered to the GskGLRenderer.
The format is essentially the same as GL_RGBA8 since it is normalized
between 0.0..1.0 for 8-bit components.
Fixes#4783
When surface depth switches from non-high-depth to high-depth (or vice
versa) the current surface has to be destroyed before a new one can be
created for this window. eglDestroySurface however was getting passed a
GdkDisplay, rather than the EGLDisplay it expects. As a result the old
surface did not get destroyed and the new surface could not be created
causing rendering to freeze.

Add a new GdkScrollUnit enum that represent the
unit of scroll deltas provided by GdkScrollEvent.
The unit is accessible through
gdk_scroll_event_get_unit().
We had code to do it and it never actually got used correctly. This ensures
that the popup services are attached to the parents so that they get proper
stacking orders when displayed. Additionally, it fixes popups from being
shown as their own windows in Exposé.
If we are clicking through the shadow of a window, we need to take special
care to not raise the old window on mouseUp. This is normally done by the
display server for us, so we need to use the proper API that is public to
handle this (rather than CGSSetWindowTags()). Doing so requires us to
dispatch the event to the NSView and then cancel the activcation from
the mouseDown: event there.
If we closed a key window in response to events, we need to denote another
window as the new key window. This is easiest to do from an idle so that
we don't clobber notification pairs of "did resign"/"did become" key
window.
We have a sorted set of surfaces by display server stacking, so we can
take the first one we come across that is already mapped and re-show it
to become key/main.
If we have server-side decorations we might need to request a layout in
response to the resize notification. We don't need to do this in other
cases because we already handle that in the process of doing the resize
(and that code is that way because of delayed delivery of NSNotification).
