We use the PMF syntax so the isValid() check is unnecessary as the
compiler will notify about wrong signal at compile time. It makes
writing autotests feel less boilerplaty.
It adds more test cases in OutputChangesTest, particularly swapping
outputs.
Swapping outputs is an interesting case because outputs can temporarily
overlap so workspace()->outputAt() can return wrong output and the
window is going to stick to wrong output.
Currently the Workspace processes output updates as they occur, e.g.
when the drm backend scans connectors, the Workspace will handle
hotplugged outputs one by one or if an output configuration changes the
mode of several outputs, the workspace will process output layout
updates one by one instead of handling it in one pass. The main reason
for the current behavior is simplicity.
However, that can create issues because it's possible that the output
layout will be temporarily in degenerate state and features such as
sticking windows to their outputs will be broken.
In order to fix that, this change makes the Workspace process batched
output updates. There are several challenges - disconnected outputs have
to be alive when the outputsQueried signal is emitted, the workspace
needs to determine what outputs have been added or removed on its own.
Separate trigger progress and semantic progress in gesture.
Move effect activation and desktop switching over to semantic progress.
Allow semantic progress to exceed 1 for overshoot in animations.
I've added VerticalAxis, HorizontalAxis, DirectionlessSwipe and BiDirectionalPinch gestures directions.
These are all combinations of other gesture directions that semantically work well together.
I've implemented these gestures as well as changed some labels and improved documentation,
Also,
Add vector signal to SwipeGesture
- 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.
This might be the root cause of random ASAN errors in testQuickTiling.
From commit 617291c6974d232ee99c4c49e891ce16863e3d6e:
The internal EventQueue is a child of the registry object. This means
that after the registry is destroyed, all proxy objects in that event
queue are going to have invalid reference to it, which is not a problem
as long as the wl_display_dispatch() function is not called.
The wl_display_dispatch() function uses wl_proxy's queue reference to
enqueue incoming events to that queue.
Unfortunately, during teardown, the internal ConnectionThread may
dispatch events right after the registry object has been destroyed,
which can lead to a crash.
In order to fix the crash, we need to destroy all proxy objects and only
after that we can destroy the event queue. It's okay if wayland events
are dispatched in between.
i.e. the EventQueue object must be destroyed last to ensure avoid hitting
dangling pointers.
This enables again the crossfade between the old window picture and the new one in the maximize and morphingpopup effects.
It does that with the OffScreenEffect redirect() feature.

Things such as Output, InputDevice and so on are made to be
multi-purpose. In order to make this separation more clear, this change
moves that code in the core directory. Some things still link to the
abstraction level above (kwin), they can be tackled in future refactors.
Ideally code in core/ should depend either on other code in core/ or
system libs.
Other policy enums are declared in options.h so let's do the same for
placement policy. Besides consistency, another advantage of moving the
enum in kwin namespace is that the enum could be forward declared.
An application that does not support text-input has no way of
communicating with the input method, so even if you show the input
method the application receives nothing. As a fallback, instead send
fake key events so the application still gets something at least.
The key events are synthesised based on the text string that the
input method sends, which may result in things that do not actually
correspond to real keys. Unfortunately I do not see a way around that.

Currently, the main user of these two functions is the X11 standalone
platform.
This change ports that code to Workspace::geometry(), which is not great
but the X11 backend already depends on the Workspace indirectly via the
Screens. Not sure if it's worth making the standalone X11 backend track
the xinerama rect internally.
This class can be used to create an anonymous file, for instance
to pass data between compositor and clients, through means of a
file descriptor, as is done in various Wayland protocols, notably
the keymap exchange.
It also implements sealing the file, so that it can be shared
between multiple clients without them being able to modify it.
If supported, memfd_create is used, otherwise a `QTemporaryFile`
is used.

Since the screen number is well-known, we can look up the default
screen on demand. Note that xcb_get_setup() is pretty cheap as it
simply returns a const pointer to pre-allocated data.
At the moment, a platform should provide two output lists - one that
lists all available outputs, and the other one that contains only
enabled outputs. In general, this amounts to some boilerplate code and
forces backends to be implemented in some certain way, which sometimes
is inconvenient, e.g. if an output is disabled or enabled, it will be
simpler if we only change Output::isEnabled(), otherwise we need to
start accounting for corner cases such as the order in which
Output::isEnabled() and Platform::enabledOutputs() are changed, etc.
In X11 when a window is maximised if the client is unable to fufill the
space provided we centre align the window.
With the new floating point geometry behaviour of centreing changes.
Instead of a 1 pixel gap at the top, we get a 0.5 pixel gap either side.
When we get into the codepath to "fix" the window in `closeHeight` we
only move the top, giving us an invalid buffer size.
We don't really want to change the logic here; on xwayland with the
scaling opt-out path it's feasible for a floating sized logical size to
still be representable. This code rounds to the native unit after all
the logic has taken effect.
It's important for tablet devices to be able to specify to which section
of the display we'll be fitting the tablet. This setting allows to
specify this by providing some options that will do so relative to the
output size.

The Session can be useful not only to the platform backend but also
input backends and for things such as vt switching, etc. Therefore it's
better to have the Application own the Session.
