This fixes not sending frame callbacks for tablet cursors. And in general
this simplifies the code by removing a level of indirection responsible for
communicating the frame timestamps, the Compositor can tell the CursorSource
the frame time directly.
The currently used cursor theme can be different from the configured one.
For example, if the configured theme cannot be used.
In order to ensure that that case is handled well, this change makes the
shake cursor plugin uses the same cursor theme as PointerInputRedirection.
As Wayland doesn't have a warp event yet, before this commit, warps were
dealt with like normal absolute motion events. This trips up games though,
which don't deal with actual absolute motion events well. As a solution
to that, until an actual warp event is a thing, we send a motion event with
a position + a relative motion event with no motion

Allow users to configure a virtual edge barrier between screens.
The pointer will only cross over to the other screen after the distance
travelled surpasses edgeBarrier.
Reduce the speed during interactive moveresize, at edges that trigger,
and at the corner.
Only supports wayland. Doesn't have X11 support since it is far too
complicated there.

this improves the out of the box behavior which has regressed a bit over
time. since we default to kcfg_ActiveMouseScreen=true the active screen
by default follows the pointer. during early startup we position the
pointer on a Placeholder output, this output does eventually get
replaced by the real output(s). because of the update logic we'd
re-position the pointer on the closest real output, but that isn't
necessarily the intended primary output.
e.g. consider an eDP + HDMI setup depending on the geometries involved
the cursor may end up on the HDMI screen by default rather than the eDP
resulting in plasma-welcome opening on the HDMI output.
to mitigate this problem we now track whether the last output was a
placeholder and if so we instead try to position the pointer on the
current primary output
We want the platform cursor to have roughly the same lifespan as the
application.
By using QObject parent mechanism, this gets deleted after the
Application destructor in the QObject destructor.
This causes an issue that removing an event filter (used by the X11
cursor) calls into the application singleton which is no longer valid.
BUG: 465970
The ImageCursorSource used to be primarily a porting aid. That is, if we
couldn't port some code to SurfaceCursorSource or ShapeCursorSource, the
ImageCursorSource was used in interim. Now, all parts of kwin have been
ported to ShapeCursorSource and SurfaceCursorSource, so the image cursor
source can be dropped.
Currently the tablet cursor doesn't use SurfaceCursorSource because it
doesn't handle changing the surface size after the set_cursor request.
This change adds missing surface commit handling in the
SurfaceCursorSource so the tablet cursor can use it. As a side effect,
the pointer interface doesn't need to track surface commits anymore.
This change introduces InputDevice::pointerFrame(). The main motivation
behind it is to allow batching multiple pointer events within a single
event frame.
BUG: 454428
PointerInterface is a "Server-managed multicasting resource". As in we
have one QObject, managed by the server, but internally it represents
multiple resources from various clients.
We cannot control the lifespan of those resources, they may persist long
after we stop having these capabilities on the seat.
If we delete our pointer object when we stop advertising a pointer
capability we have race conditions with clients calling release, or
potentially even having a seat_get_pointer in flight.
It's easier and safer just to have PointerInterface last as long as the
Seat. If we don't have a mouse no-one should try to bind, and even if
they did or remained bound long after we stop having a mouse it won't do
any harm as there are no mouse events to broadcast.
The contents of the cursor can be either a normal image or a wl_surface.
At the moment, we get an image from the wl_surface. But it's going to be
changed so we use SurfaceItem to render wl_surface cursors.
SurfaceCursorSource provides the way to get the wl_surface handle from
the cursor. In order to provide backwards compatibility, it also provides
a QImage.
Currently, kwin blits the dnd icon onto the cursor image. This doesn't
work on mobile because the cursor is usually hidden there.
As a short term solution, put the dnd icon in the Scene. In the future,
it needs to be put in its own render layer.
ShapeCursorSource provides the contents of the given cursor shape in the
Xcursor theme.
If the given cursor shape is animated, ShapeCursorSource will keep
updating its content based on the value of current sprite's delay value.
Use isNull on QSizeF to check for a zero delta instead of comparing it
with a default-constructed QSizeF, which in practice initializes to
(-1.0,-1.0). This caused relative motion events to be omitted if the
delta happened to be equal to (-1.0,-1.0), causing mouse jumping in some
applications.
BUG: 444510

In libinput 1.19, three new pointer axis events were added in order to
provide support for high-resolution scrolling.
LIBINPUT_EVENT_POINTER_AXIS is de-facto deprecated and new users of
libinput should use instead SCROLL_WHEEL, SCROLL_FINGER, and
SCROLL_CONTINUOUS.
Discrete deltas were replaced with v120 delta values. 120 corresponds to
a single discrete delta. Smaller values correspond to "partial" wheel
ticks.

The .clang-format file is based on the one in ECM except the following
style options:
- AlwaysBreakBeforeMultilineStrings
- BinPackArguments
- BinPackParameters
- ColumnLimit
- BreakBeforeBraces
- KeepEmptyLinesAtTheStartOfBlocks
Otherwise animated cursors won't work. Hopefully, this will fix pointer
input test.
It would be great to refactor cursor handling so it's simpler, it can be
done later.
This simplifies focus related logic a bit. Instead of differentiating
between wayland and internal window focus, simply maintain window focus
that works both with regular wayland windows as well as the ones created
by kwin.
The main motivation behind this change is to prepare input abstractions
for virtual input devices so the wl_seat can properly advertise caps or
the cursor getting properly mapped/unmapped when a fake pointer is
added/removed on a system without a hardware mouse connected.
With this, there are three abstractions - InputDevice, InputBackend, and
InputRedirection.
An InputDevice represents an input device such as a mouse, a keyboard, a
tablet, etc. The InputBackend class notifies the InputRedirection about
(dis-)connected devices. The InputRedirection manages the input devices.
Such design allows to unify the event flow for real and virtual input
devices.
There can be several input backends active. For example, the libinput
backend and an input backend that provides virtual input devices, e.g.
libeis or org_kde_kwin_fake_input.
InputDeviceHandler keeps track of which client has focus, and whether
the decoration or main window has focus.
Should the decoration get destroyed whilst the decoration has focus we
don't update correctly. This can happen when
"BorderlessMaximizedWindows" is set, or if you use key presses whilst
above the decoration.
cleanupDecoration (which is an odd name) is called whenever a decoration
gains or loses focus. Here we can connect for the decoration destruction
and force a focus change.
BUG: 411884
API-wise it's odd to require absolute position with relative pointer
moves.
This cleans up some of InputRedirection code by making it simply forward
pointer input events from input devices to the pointer input device
handler, which knows better what to do with the delta value.
The pointer input device handler will compute the absolute position based
on the specified delta value, but it could also do something else, e.g.
not move the pointer at all if it's locked, etc.
Once in a while, we receive complaints from other fellow KDE developers
about the file organization of kwin. This change addresses some of those
complaints by moving all of source code in a separate directory, src/,
thus making the project structure more traditional. Things such as tests
are kept in their own toplevel directories.
This change may wreak havoc on merge requests that add new files to kwin,
but if a patch modifies an already existing file, git should be smart
enough to figure out that the file has been relocated.
We may potentially split the src/ directory further to make navigating
the source code easier, but hopefully this is good enough already.
The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.
In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.
WaylandCursorImage::loadThemeCursor(const T &shape) uses templates.
These templates are used by input.cpp but the deifnition is in
pointer_input.cpp
On some setups this creates a compilation problem.
This patch introduces an explicit non-templated declaration with the
defintion explicitly complied into the same class.
In master this has been refactored away anyway, so this is a minimal
patch to make things working in the least invasive way.
BUG: 423052
Currently in order to load an Xcursor theme, kwin uses libwayland api,
which looks really awkward because of the way how the compositor talks
to itself via the internal connection.
The main motivation behind this change is to limit the usage of kwayland
client api in kwin.
Summary:
As is KWin only had 1 Cursor which was a singleton. This made it impossible for
us to properly implement the tablet (as in drawing tablets) support and show where
we're drawing.
This patch makes it possible to have different Cursors in KWin, it makes all the
current code still follow the mouse but the tablet can still render a cursor.
Test Plan: Tests pass, been using it and works as well as before but with beautiful tablet cursors.
