Currently, if a window switches between SSD and CSD, it is possible to
encounter a "corrupted" state where the server-side decoration is wrapped
around the window while it still has the client-side decoration.
The xdg-decoration protocol fixes this problem by saying that decoration
updates are bound to xdg_surface configure events.
At the moment, kwin sort of applies decoration updates immediately. With
this change, decoration updates will be done according to the spec.
If the compositor wants to create a decoration, it will send a configure
event and apply the decoration when the configure event is acked by the
client. In order to send the configure event with a good window geometry
size, kwin will create the decoration to query the border size but not
assign it to the client yet. As is, KDecoration api doesn't make
querying the border size ahead of time easy. The decoration plugin can
assign arbitrary border sizes to windows as it pleases it. We could change
that, but it effectively means starting KDecoration3 and setting existing
window deco ecosystem around kwin on fire the second time, that's off the
table.
If the compositor wants to remove the decoration, it will send a
configure event. When the configure event is acked and the surface is
committed, the window decoration will be destroyed.
Sync'ing decoration updates to configure events ensures that we cannot
end up with having both client-side and server-side decoration. It also
helps us to fix a bunch of geometry related issues caused by creating
and destroying the decoration without any surface buffer attached yet.
BUG: 445259
It's more common to see the parent object being the last argument in Qt
and this way you won't need to specify nullptr parent explicitly if the
xdg-popup or the xdg-toplevel surface doesn't need to be configured
implicitly, which makes tests slightly easier to read.
With a "Surface" type in kwin, KWayland::Client::Surface without fully
specified namespace will conflict with kwin's Surface type.
In some way, it also improves readability as it's clear where Surface
comes from.
Active output is a window management concept. It indicates what output
new windows have to be placed on if they have no output hint. So
Workspace seems to be a better place for it than the Screens class, which
is obsolete.
When debugging modifier_only_shortcut_test in _waylandonly mode I saw
that it was failing, among other things, because some aspects were not
initialised.
This changes every test we have to run the new
Test::initWaylandWorkspace() that calls waylandServer()->initWorkspace()
but also makes sure that WaylandServer::initialized is emitted before we
proceed.
There were multiple other cases of placing the mouse between screens at
the start of tests. It seems to be all copy paste.
Only maximise and pointerConstraints were failing before this, but we
may as well fix all of them.
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.
The new signal is emitted when the Application has fully been initialized.
It allows us to change the startup sequence, for example create workspace
before starting the Xwayland server, without making any adjustments in our
test suit.
Summary:
This change splits the XdgShellClient class to better match existing
abstractions in the xdg-shell protocol and fix a few issues related to
sending configure events.
In the new client classes, configure events are handled differently.
Instead of blocking configure events, we try to send them as late as
possible. Delaying configure events will let us merge changeMaximize()
for X11 clients and Wayland clients and it also fixes the bug where
we don't send the final configure event when user has finished resizing
a window.
Given that configure events are not sent immediately, XdgSurfaceClient
keeps the last requested frame geometry and the last requested client
geometry.
This patch doesn't intend to fix all issues in kwin's implementation of
the xdg-shell protocol. For example, we still handle surface unmapping
very poorly.
Test Plan: Tests pass.

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.

Summary:
Currently, we have only one shell client type - XdgShellClient. We use
it when we are dealing with Wayland clients. But it isn't really a good
idea because we may need to support shell surfaces other than xdg-shell
ones, for example input panel surfaces.
In order to make kwin more extensible, this change replaces all usages
of the XdgShellClient class with the AbstractClient class.
Test Plan: Existing tests pass.

Summary:
Currently we have two signals that are emitted when the Toplevel's geometry
changes - geometryShapeChanged() and geometryChanged(). The former signal
is used primarily to invalidate cached window quads and the latter is
sort of emitted when the frame geometry changes. But it's not that easy. We
have a bunch of connects that link those signals together...
The worst part about all of this is that the window quads cache gets
invalidated every time a geometry update occurs, for example when user
moves a window around on the screen.
This change introduces a new signal and deprecates the existing geometryChanged
signal. frameGeometryChanged is similar to geometryChanged except that it is
emitted when an _actual_ geometry change has occurred.
We do still emit geometryShapeChanged signal. However, in long term, we
need to get rid of this signal or come up with something that makes sense
and doesn't require us to waste computational resources.

Summary:
In order to properly implement xdg_surface.set_window_geometry we need
two kinds of geometry - frame and buffer. The frame geometry specifies
visible bounds of the client on the screen, excluding client-side drop
shadows. The buffer geometry specifies rectangle on the screen that the
attached buffer or x11 pixmap occupies on the screen.
This change renames the geometry property to frameGeometry in order to
reflect the new meaning assigned to it as well to make it easier to
differentiate between frame geometry and buffer geometry in the future.

Summary:
This change removes all traces of wl-shell in the test suite. That's a
prerequisite for dropping wl-shell support in KWin.
Given that wl-shell and xdg-shell are not interchangeable, some tests
were removed and initialization sequence in some tests was adjusted.
The most notable change is ensuring that each plasmashell window sets
its role and initial position before committing the surface. Setting
those properties before the first surface commit is important because
our window placement code needs to know window type in order to
avoid maximizing panels, popups, etc.

Summary:
Currently popups get positioned once at the initial configure, to set
the correct size and again when they are mapped.
Toplevels are currently only positioned when they are mapped. This works
for all cases where the the toplevel defines its own size, but not if
the window should have an initial size set by the placement strategy or
window rules. Most notably the maximised placement strategy used on
plasma mobile.
Being out of sync and resizing later currently causes a positioning bug
when plasma mobile is used with XdgShell.
This patch repositions all top levels that don't have a position set
through the plasma interface.

Summary:
A new namespace KWin::Test is added which provides a few helper
functions. It makes it easy to setup a KWayland client connection with
the base set to be able to create a Surface and flags to create
additional interfaces. This replaces the KWayland connection dance in
init() methods. For cleanup() there is also a dedicated helper function.
In addition there are helper functions to:
* render a surface
* create a surface
* create a shell surface
* flush the wayland client connection
* access to the created interfaces - for compatibility with existing code
The idea is to extend this Test library also for other common use cases
like creating an X11 connection and X11 windows, etc.
