Non-current output modes were deprecated due to various reasons, e.g.
it's not possible to remove some nodes; two modes can have the same
resolution and the refresh rate but different flags, but wl_output.mode
fails to communicate that properly; the usefulness of non-current modes
is questionable. For more details, please refer to [1].

The usage of nested private classes is highly discouraged in
kwaylandserver due to various reasons, e.g. it's easy to forget to put
Q_DECL_HIDDEN, etc.
Currently, the SurfaceInterface class has a signal that is emitted
whenever any sub-surfaces in its sub-tree changes in a way that requires
a repaint. It is emitted when a sub-surface is resized, moved, or
damaged, etc. There is no way for the compositor to track changes in the
stacking order of sub-surfaces efficiently.
This change replaces the subTreeChanged signal with a less noisy signal
that's emitted whenever the list of direct child sub-surfaces changes.
This is needed for keyboard grabs. If the seat is notified about a
keyboard event, it will need to forward the event to the grab object,
which in its turn will decide what should happen to the event.
When hot plugging outputs, we may hit the wl_global race condition.
We need to delay the destruction of output device globals to prevent
hitting that race condition.
Destroying a global leads to a race on the client. If a client binds
at just the wrong moment they will use an invalid ID and cause a
protocol error. The current best thing to do is to announce the removal
then remove the global (and thus the ID) only after a delay. Non-ideal,
but better than nothing.
Pragmatically this affects only:
Blur/Contrast/Slide/Output/OutputDevice

In plasma code, it's more common to see `/** ... */` doxygen comments
rather than `/** ... **/`.
This change fixes up doxygen comment terminators to prevent inconsistency
issues.
An xdg_imported resource must be created no matter whether there is an
exported surface with the specified handle.
This change fixes handling of that case in kwaylandserver by introducing
a dummy imported object.
If there is no exported surface with the given handle, the compositor
should create an xdg_imported resource and immediately send the
destroyed event.
A dummy imported object is needed because generated code sets resource
implementation; otherwise we would set an implementation without any
user data to mark the resource as inert.
XdgImportedV2Interface already knows what the associated resource is, so
we can call send_destroyed() method that takes no resource to let auto
generated code figure out what resource must be used. It simplifies code.
There's no point for using the d-pointer pattern because the importer
and the exporter classes are private already, they are not exposed in
public api.
Currently, testXdgForeign fails because imported and exported resources
are destroyed immediately from destructor request handlers and code that
performs cleanup in the exported-imported mapping tables accesses the
dangling pointers.
Previously, it wasn't an issue because the destruction of exported and
imported resources was delayed using QObject::deleteLater().
In zxdg_output_v1 version 3, done is deprecated and should be replaced
with wl_output.done. This makes automatically send done upon change not
suitable for the usage. OutputInterface user should now use done()
explicitly to send the update.
CCBUG: 433224
Currently, plasma window model test fails because the null icon is
received after executing the main body of the test.
FAIL! : PlasmaWindowModelTest::testVirtualDesktops() '!dataChangedSpy.wait(100)' returned FALSE. ()
Loc: [/data/projects/src/kwayland-server/autotests/client/test_plasma_window_model.cpp(583)]
We can fix the test by waiting for the iconChanged signal to be emitted,
but we will need to wait in all tests too. Furthermore, it doesn't make a
lot of sense to wait for an icon that was never set.
This change makes the compositor send an icon only if there is one.
It's a behavioral change, but it shouldn't regress anything because kwin
always sets icons via the plasma window management protocol even for apps
that have no valid app id.
It also makes the api of the PlasmaWindowInterface class more intuitive.
Currently, testIcon fails because the actual and the expected pixmaps
have mismatching formats.
The root cause is that images with an alpha channel will loose the alpha
channel if they are converted to QPixmap using QPixmap::fromImage().
The >> stream operator for the QPixmap class will deserialize pixel data
in a temporary QImage and then use QPixmap::fromImage() to get a pixmap
object.
The >> stream operator for the QIcon class will delegate the task of
reading the icon from a QDataStream to QPixmapIconEngine, which uses the
>> stream operator under the hood to deserialize icon data.
In order to fix testIcon, this change constructs a dummy icon from a
pixmap object returned by QPixmap::fromImage().
Currently, we have a mix of Frameworks versions and Plasma versions in
@since tags, which leads to some confusion. Since this is an unstable
library, one cannot rely on since version tags, we are free to add,
change, and remove apis to serve best to kwin requirements. Thus, we can
simply remove all since version tags to fix mixing up different product
versions.
If a Wayland protocol deals with regions, they will be exposed as
QRegion objects in public API. Therefore, it makes sense to make
RegionInterface private as it's an implementation detail and it's
not intended to be used in public api.
The corresponding test was dropped because the CompositorInterface
no longer emits a signal to indicate that a wl_region has been created.
It should be also noted that wl_region stuff is already tested via
other means, e.g. surface damage, etc.
testError expects that the compositor will post a protocol error if the
client tries to create several plasma shell surfaces for the same wayland
surface.
