It's the same as the currentDesktop except that it's a VirtualDesktop
object.
The main advantage of the currentVirtualDesktop property is that it
doesn't change if a virtual desktop is added or removed in the middle.
It also makes dealing with virtual desktop changes easier.
With the new virtual desktops model, a window can be on several virtual
desktops. Currently, scripts have no any way to get the list of desktops
the window is on. This change addresses that.
Currently, window thumbnails may be placed behind the panel, which
doesn't look good.
With this, the window heap will cover the same area as the maximize
area.
This makes the WindowHeap more robust to layout changes. Currently, the
main issue with it is that thumbnails will be misplaced if the heap's
scene position changes.
Kirigami.ScenePosition automagically keeps track of the item's scene pos.
If a window is on several virtual desktops, Workspace::switchWindow()
will not work as expected because AbstractClient::desktop() returns the
id of the last virtual desktop.
Since the active window is most likely on the current virtual desktop,
we can use that for filtering out irrelevant windows.
The new overloads take the client (as context) and the desired screen id
or a point and return the client area.
The main motivation behind this change is to make the transition to the
new virtual desktop model where a window can be on several desktops less
painful.
In the recent refactor we made it so environment variables got synced to
the Application::processStartupEnvironment.
It then seemed safe and cleaner to remove the qputenv calls, but this
was not the case. It regressed the unit tests on CI and kglobalaccel
which is another path where kwin spawns clients.
Syncs the primary selection from wayland to X and from X to wayland.
Instead of doing it through the internal connection like the clipboard,
this sets/reacts to changes in SeatInterface::prrimarySelection directly.

This effect is meant to be as a replacement for the present windows and
the desktop grid effect. It is written using QML.
So far, this effect implements only the basic features of the present
windows effect. Desktop management features will be added later.

This allows changing the type of desk to QVector<VirtualDesktop *>.
Based on the dont_activate flag, Workspace::sendClientToDesktop() will
try to focus the window if it's moved to the current virtual desktop.
In order to implement that, it needs to know whether the window has been
on the current desktop. c->isOnDesktop(desk) is a much sophisticated way
to do that.
Workspace::takeActivity() forces the modal dialog and its parent window
to be on the same virtual desktop. It uses int-based desktop ids for
that purpose.
This change ports the relevant parts of Workspace::takeActivity() to the
VirtualDesktop object.
This way if kwin_wayland crashes we don't need to ensure that new
environment variables need to get synced across the new env.
This fixes an issue where spawning an xwayland application from a
wayland window that survives a crash would fail.
By moving the logic here we no longer need to wait for kwin_wayland to
start before starting plasmashell or even ksmserver as all environment
variables are set. As long as the wrapper is ready we can continue
starting and clients will just block on connect.
That should still allow for both a lot of optimisations both for speed
and cleaning up the startplasma-wayland scripts.
This will be addressed in follow up patches.
Use of kwin_wayland directly with xwayland is still supported for
testing.
The initial goal of kwin_wrapper was that it would set up all relevant
environment variables that will be used by the clients of kwin.
This meant having to cache old variables before we overrode them and
pass additional settings to the backends for the old wayland_display. It
works, but with X11 about to move too ends up being unnecessarily
complex. In hindsight it's easier for kwin to have the environment
represent the platform it is currently on, and have kwin explicitly set
variables in the QProcessEnvironment of the session it forks itnto.
This patch is changed so that we set the wayland socket name used by the
wrapper explicitly which is then used by the process environment kwin
uses for the main session.
If a window is on several desktops, AbstractClient::desktop() will
return the id of the last desktop.
For example, if a window is on virtual desktops A and B, the desktop()
function will return the id of desktop B. This can be the culprit for
bugs such as window snapping not working as expected when moving a
window on virtual desktop A, e.g.
- moved window is on desktops A, and C. desktop() returns the id of C
- snap candidate (l) is on desktops A, and B. desktop() returns the id
of B
Even though the snap candidate window and the moved window are both on
the same desktop (A), the moved window won't be snapped because the
desktop() function returns garbage values.
To fix that, the workspace needs to check whether the window is on the
current desktop.
For what it's worth, that's also how the workspace handles windows being
on multiple activities.
This patch has one behavioral change - raiseOrLowerClient() will not
work if the client is not on the current virtual desktop.
However, raiseOrLowerClient() can be called only in two cases:
* user triggers the raise or lower shortcut for the active client. Since
the active client is on the current virtual desktop, it's not an issue
* an x11 window restacks itself. It makes no sense if an x11 window
restacks itself while it's inactive or not on current virtual desktop.
Also, the Opposite restack mode is rarely used, some window managers
don't even bother implementing it. So, having such a constraint should
not be a problem.
The main reason for not allowing raiseOrLowerClient() for windows that
are not on the current virtual desktop is that a window can be on
multiple virtual desktops. If a window is on A and B virtual desktops,
the only logical option is to toggle stacking position if the window is
on the current desktop. It's the only viable option as kwin does not
maintain per virtual desktop stacking order.
IN_FORMATS contains information about which buffer formats can be
scanned out with a given drm plane. Using these plane-specific
format+modifier combinations as well as explicit modifiers in
general can yield bandwidth and performance improvements,
especially in multi-gpu systems.
We use surfaceless contexts with internal windows. We also require
the EGL_KHR_surfaceless_context extension for making context current
without outputs.
Arguably, we could use pbuffers, but since mainstream drivers (Mesa and
NVIDIA) support surfaceless contexts, the extra complexity doesn't buy
us anything.
This reverts commit ac16bef409.
It causes crashes and color channels seem to be swapped.
GLTexture::toImage() needs more work before it can be used in the
screenshot effect, or maybe dropped.
In a recent refactor screens are only created when our xdg_surface has
been acked. This leaves a window where m_waylandCursor is null and
events are still being processed.
With per-screen rendering, every output may have different EGLConfig.
Having a single global EGLConfig doesn't work out well.
This change removes Platform::sceneEglConfig(). It's used primarily to
create the global share context. In hindsight, the global share context
can be created without EGLConfig as it's never made current.
EGL_NO_CONFIG_KHR is part of EGL_KHR_no_config_context extension, which
is supported by both Mesa and NVIDIA driver so it should be safe to make
it mandatory.
At this point, desktop() is -1 since the client hasn't been moved to any
virtual desktop yet.
It seems like checking desktop() is a typo. It makes more sense to check
desktopId.
