This change introduces InputDevice::pointerFrame(). The main motivation
behind it is to allow batching multiple pointer events within a single
event frame.
BUG: 454428
The normal stacking order contains managed and unmanaged windows now.
This kind of breaks dragging from X11 to Wayland clients.
When an X11 client is the drag source, it's going to create an override
redirect window for the drag icon, which is beneath the pointer.
findManagedToplevel() will return the drag icon instead of the window
beneath the drag icon.
The root problem is that normal event processing has different needs. It
doesn't care about window type except when the screen is locked, while
dnd does. Perhaps it also makes sense to check whether the window accepts
focus.
This change introduces a specialized helper to pick the drag target.
Unfortunately, it amounts to some code duplication. On the other hand,
not sure that other options (such as adding flags to findToplevel()) are
better.
Using OutputBackend::outputsQueried can cause problems because it's emitted
before output settings like enablement get adjusted to the new output configuration.
It also doesn't react to output changes initiated by KScreen and is in the
way of plans to use multiple output backends at the same time.
BUG: 461901
With the addition of KGlobalAccel::globalShortcutActiveChanged(),
there's a way to monitor all triggered actions without adding any
boilerplate code.
This change removes the KGlobalAccel bits from the Platform class. This
reduces the amount of boilerplate code; currently we need to be careful
about ensuring that Platform::setupActionForKGlobalAccel() is called.
Another reason behind this change is to simplify the api of Platform and
remove things that don't have anything to do with outputs.
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.

- Now only 1 GestureDirection enum
- Now only 1 registerGesture() call
- The 4 kinds of gesture (Pinch/Swipe) and (Touchpad/Touchscreen) in globalshortcuts.h/cpp are merged into 1 GestureShortcut
- Change from range to set of finger counts in gestures
No behavior should change, just a refactor.
With fractional scaling integer based logical geometry may not match
device pixels. Once we have a floating point base we can fix that. This
also is
important for our X11 scale override, with a scale of 2 we could
get logical sizes with halves.
We already have all input being floating point, this doubles down on it
for all remaining geometry.
- Outputs remain integer to ensure that any screen on the right remains
aligned.
- Placement also remains integer based for now.
- Repainting is untouched as we always expand outwards
(QRectF::toAdjustedRect().
- Decoration is untouched for now
- Rules are integer in the config, but floating in the adjusting/API
This should also be fine.
At some point we'll add a method to snap to the device pixel
grid. Effectively `round(value * dpr) / dpr` though right now things
mostly work.
This also gets rid of a lot of hacks for QRect right and bottom which
are very
confusing.
Parts to watch out in the port are:
QRectF::contains now includes edges
QRectF::right and bottom are now sane so previous hacks have to be
removed
QRectF(QPoint, QPoint) behaves differently for the same reason
QRectF::center too
In test results some adjusted values which are the result of
QRect.center because using QRectF's center should behave the same to the
user.
The IdleDetector is an idle detection helper. Its purpose is to reduce
code duplication in our private KIdleTime plugin and the idle wayland
protocol, and make user activity simulation less error prone.

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.
Currently, input events can flow directly to input device handlers and
sometimes they go through the InputRedirection, which simply forwards
them to the corresponding input device handler.
When libinput tears down, it may access the Session object. This change
re-jitters the shut down logic so the Session object is guaranteed to be
valid when libinput stuff gets destroyed.

This lays down some groundwork for realtime gestures in Wayland,
so that gestures that are 1:1 with user motion on a touchpad are
now possible to implement.
Due to earlier commits, this is mostly just glue code to make a
convenient API.
Gestures implemented with this API are four-finger gestures, to
avoid conflicting with apps that may use two or three-finger
gestures.
Currently, the Workspace has no any api to constrain one window above
another. This results in having hacks such as keepDeletedTransientAbove()
This change introduces a basic api to constrain a given window above
another. It can be used for ensuring that transient windows are placed
above their parents. It also can be used for stacking the outline window
below the move-resize window.
Internal windows may also have transient parents. Because of that, this
change makes the workspace add internal clients to the stacking order by
default. The good thing about it is that it allows us unify some input
related code for "external" windows and internal windows.
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.
