We need to also destroy all idle objects when we tear down the
internal client connection. Otherwise the cleanup tries to free
the object after our Wayland connection is already destroyed.
KSld goes to state AcquiringLock when starting the greeter process.
During this state it expects the input to be grabbed. So from KWin
perspective this means that the screen is locked and KWin should
filter out input events.
We announce support for it and depending on whether we have a plugin
or not set the default mode to Server or None.
When a decoration interface is created it gets installed on the
ShellClient. But there it isn't properly used yet as we don't have
support for decorations in ShellClient yet.
Need to pass a proper env to ScreenLocker to ensure we don't mess
with the greeter's environment by e.g. unsetting QT_IM_MODULE or
setting EGL_PLATFORM.

Ensures that all Wayland objects are destroyed and the cleanup handling
is performed before tearing down the Compositor. This fixes for example
a crash if a Surface with a Shadow is still around at tear down.
This introduces Toplevel::isLockScreen() and Toplevel::isInputMethod(),
this can be used to allow only lockscreen/inputmethods to get input
events and shown when screen is locked.
We need to destroy the ClientConnections we create. Also we need
to disconnect our Xwayland error handling before destroying it, otherwise
it would trigger the abort for crashing Xwayland.
ASAN righly complained: we need to delete our Wayland objects before
we destroy the internal client connection. Solved by better setting
parent relationships in the QPA plugin and correctly delete objects
in destroy of internal client connection.
We need to destroy the compositor after Xwayland terminated and after
the internal Wayland connection is destroyed. This means when destroying
the Workspace we may no longer destroy the Compositor at the same time.
Also we need to ensure that other tear down functionality doesn't call
into the no longer existing internal client connection.
With this change kwin doesn't crash when exiting with Wayland and/or
X11 windows still open.
This allows to check if specific ShellClient is from LockScreen or not,
as well as this adds method to verify if ShellClient is from input
method like maliit.
Now that KWin knows about which window is from Screenlocker it can apply
various security restrictions like no other window then greeter is on
top of it.

This introduces --lockscreen option in kwin_wayland which when used will
lock screen immediately. Also dependency to newly created kscreenlocker
repo is introduced.

Our server announces the DpmsManagerInterface and in the DRM backend
we announce support for Dpms on the OutputInterface (if the Output
supports it) and we connect to changing Dpms requests.
Allows to interact with the Registry for the internal connection in
other parts of KWin and makes it possible to create more than just the
ShmPool for this Registry.
For Wayland clients we now are able to get shadows.
Internally this reuses large parts of the X11 implementation. This
could be improved to make the Scene's better aware of the Wayland
shadow, so that less memory is needed.
The creation of PlasmaWindowInterface is moved from WaylandServer into
AbstractClient. This allows the sub classes to better control when to
create/destroy the Client.
For creation it's bound to becoming visible - that is Windows which are
only created but never shown are not announced at all.
For Client it's destroyed with the normal tear-down of a Client, for
ShellClient it's destroyed on unmapped (which also means a new one
will be created again in case of another mapping of the surface).
As a side effect, this works around the problem that ShellClients do not
yet get destroyed for QtWayland's menus (needs further investigation).
Ensures that the PlasmaWindow gets destroyed together with the window.
Note: when a ShellClient gets unmapped the PlasmaWindow does not yet
get destroyed. It should probably get destroyed and recreated on next
mapping.
If the icon doesn't have a name, we pass the generic xorg icon. Most
likely our xwayland clients won't have a theme name, so giving them
the xorg icon seems a good enough work around. If we would want to
pass the real icon for xwayland clients we would need a way to
serialize them which seems like quite some needless overhead for legacy
applications. Can be considered for the future nevertheless.
With Xwayland clients it can happen that the window gets destroyed
before it ever got a surface (Qt 5's file open dialog being an example).
This change delays such clients till it got the surface, removing not
needed roundtrips and possible problems.
So far this only allows to trigger show desktop functionality and exports
the state.
In future this should be restricted to just one dedicated desktop shell
process.
Input-method servers, like maliit, need to be known to KWin since KWin
needs to know about virtual keyboards. Virtual keyboards should be shown
as OSD layers, and they are one of the types of windows that actually
should be showable when the lock screen is active.
kwin_wayland --inputmethod /path/to/your/input-server
tries to start the input server. The input-server's window never gets
keyboard focus and is shown on top of all windows except for KWin's
internal clients.
The PlasmaShell interface allows to create a PlasmaShellSurface for a
given Surface. Through this interface the Surface can request:
* a specific position
* a window type
So far only the window types Normal, Panel and Desktop are supported
which is a sufficient subset for getting plasmashell to work.
In future there should be security checks so that only the dedicated
desktop shell can bind these interfaces.
Fixes regression introduced with 90a6814: we may not queue a signal
taking a pointer to a ShellClient as the ShellClient might be destroyed
before the queued signal is delivered.
The idea for the queued signal was to ensure that the size is set when
windowShown is emitted - this can also be achieved by first updating the
size.
When a ShellClient is added and it's not internal, it get placed just
like any other Client. This needs to happen after the initial size is
determined.
Please note: this breaks the positioning of popup windows (e.g. menus)
as they are placed like any other Client. This needs proper popup support
which right now does not yet exist and thus is not much difference to
before.
Adds all internal ShellClients into a dedicated list. This ensures that
we don't perform "normal" window management on them.
In addition we add them to the top of the stacking order. This restores
behavior as it is on X11: internal windows are using BypassWindowManagerHint
and thus on top of everything.
The internal used window Id consists of two parts identifiying the
Client and one identifying the Surface. That is the first 16 bits
are set to the ClientConnection, the last 16 bits are taken from
the Surface id. As the Surface id is 32 bits, but we only use 16 bits
there is a chance of overlap. So this might need some improvement.
If the ShellClient got created for a Qt internal window, we try to
find the QWindow and if we get one, we use the geometry directly as
it got set by KWin in the first place.
Also a windowId() is added to ShellClient which can be used by the
effect system to find an EffectWindow. If it's an internal QWindow
we just use that window id. For other clients we still need some
smart solution.
