On Wayland, the move resize geometry and the frame geometry are
completely out of sync.
This change synchronizes emitting of the clientStepUserMovedResized
signal to the move resize geometry changes.
It simplifies code of InternalClient and XdgSurfaceClient, and makes
adding support for other shell surface protocols easier as there's less
boilerplate stuff that you would need to take care of.
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.
Window management features were written with synchronous geometry
updates in mind. Currently, this poses a big problem on Wayland because
geometry updates are done in asynchronous fashion there.
At the moment, geometry is updated in a so called pseudo-asynchronous
fashion, meaning that the frame geometry will be reset to the old value
once geometry updates are unblocked. The main drawback of this approach
is that it is too error prone, the data flow is hard to comprehend, etc.
It is worth noting that there is already a machinery to perform async
geometry which is used during interactive move/resize operations.
This change extends the move/resize geometry usage beyond interactive
move/resize to make asynchronous geometry updates less error prone and
easier to comprehend.
With the proposed solution, all geometry updates must be done on the
move/resize geometry first. After that, the new geometry is passed on to
the Client-specific implementation of moveResizeInternal().
To be more specific, the frameGeometry() returns the current frame
geometry, it is primarily useful only to the scene. If you want to move
or resize a window, you need to use moveResizeGeometry() because it
corresponds to the last requested frame geometry.
It is worth noting that the moveResizeGeometry() returns the desired
bounding geometry. The client may commit the xdg_toplevel surface with a
slightly smaller window geometry, for example to enforce a specific
aspect ratio. The client is not allowed to resize beyond the size as
indicated in moveResizeGeometry().
The data flow is very simple: moveResize() updates the move/resize
geometry and calls the client-specific implementation of the
moveResizeInternal() method. Based on whether a configure event is
needed, moveResizeInternal() will update the frameGeometry() either
immediately or after the client commits a new buffer.
Unfortunately, both the compositor and xdg-shell clients try to update
the window geometry. It means that it's possible to have conflicts
between the two. With this change, the compositor's move resize geometry
will be synced only if there are no pending configure events, meaning
that the user doesn't try to resize the window.
This is to improve code readability and make it easier to differentiate
between methods that are used during interactive move-resize and normal
move-resize methods in the future.
This reduces the number of usages of xStackingOrder(), which simplifies
the reasoning about when it can be marked as dirty.
Since internal windows are now in the regular stack, InternalWindowTest
can use stackingOrder().
As for X11ClientTest, there's no specific reason why it uses the x stack
instead of the regular one.
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.
A window id generated by WaylandServer may reference an X11 window
with the same id, which can result in undefined behavior.
The main reason why we needed windowId() was because of the task
switcher. However, since tabbox uses internal ids now, the window id
property can be dropped.
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.
In rare cases, Workspace::restoreFocus() may fail, for example when the
most recently activated client is about to be destroyed or unmapped.
If it happens that we cannot restore the focus, then mark the window in
FocusIn event as active.
CCBUG: 424223
If AbstractClient::setFrameGeometry() is called from a slot connected
directly to the frameGeometryChanged() signal, then is there a good
chance that kwin will fall into an infinite recursion. However, that's
the case with only X11 and internal clients.
The root cause of the infinite recursion is that both X11Client and
InternalClient compare the new geometry against the geometry before
update blocking. In order to fix the bug, we simply need to ensure that
updateGeometryBeforeUpdateBlocking() has been called before we start
emitting the frameGeometryChanged() signal.
Furthermore, a couple of tests were added to ensure that we won't hit
this subtle bug again.
Unfortunately, a0c4a8e766 has a major bug
where clients that track focus events may get confused by focusToNull().
One such a notable example is Dota 2. It tracks the focus events to
minimize itself after the keyboard focus has been lost as well stop
playing music while it's in background. So, when we call focusToNull(),
Dota 2 will receive a corresponding FocusOut event and ask the window
manager to minimize it. It doesn't really matter that the FocusOut
event is going to be followed by a FocusIn event because when a window
is minimized, kwin will activate the next one in the focus chain.
Since those issues can't be fixed from the window manager's side, this
patch partially reverts a0c4a leaving only the autotest.
BUG: 424223
FIXED-IN: 5.19.4
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.
Depending on the current focus stealing prevention level, it's possible
for kwin to call XSetInputFocus() on a window that already has the input
focus. In which case, we won't receive the corresponding FocusIn event
and the client will remain inactive from kwin's perspective even though
it isn't.
In order to work around this issue, we can move the input focus to the
null window. By doing so, it's guaranteed that we're going to receive
the matching FocusIn event for the client.
This commit indirectly fixes a bug where fullscreen games are displayed
below panels.
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.

Summary:
Currently each managed X11 client is represented with an instance of
Client class, however the name of that class is very generic and the
only reason why it's called that way is because historically kwin
was created as an x11 window manager, so "Client" was a sensible choice.
With introduction of wayland support, things had changed and therefore
Client needs to be renamed to X11Client in order to better reflect what
that class stands for.
Renaming of Client to X11Client was agreed upon during the last KWin
sprint.
Test Plan: Compiles, the test suite is still green.

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.

KWin replaces any non-printable character with a space. This check does not
handle surrogate pairs correctly. Additionally, translators sometimes insert
non-printable soft-hyphens into titles, which also cause KWin to display a
space instead.
This code adds the missing surrogate handling, and (to fix both issues), also
removes non-printable characters instead of replacing them with a space.
Also moved the changed test after these changes, so that changes in non-
printable characters do not cause unneeded redraws.

Summary:
For supporting Wayland windows in the kwin_rules_dialog we need a way to
pass a window id for Wayland windows to the dialog. This id needs to be
sent to the dbus interface to query window information just like the
interactive query. For Wayland windows we don't really have a window id
and it would require to also pass the windowing system to
kwin_rules_dialog and back through the dbus interface.
To not complicate things this change introduces a windowing system
independent id based on UUID. This could in future also be used
internally for areas where it's window id based and used in both
windowing systems.
Test Plan: Adjusted test cases to verify the uuid is generated and passed to Deleted

Summary:
So far a not-active fullscreen X11 window was kept in the active layer if
the newly activated window is in the same group (that is same client
leader). For example a fullscreen X11 kwrite window is in the active layer
if another kwrite window is active. The two kwrite windows obviously
don't have anything to do with each other, but are in the same group.
This creates problems as it's not possible to raise other windows above
the active not-fullscreen kwrite window. E.g. the panel is stacked below.
The idea behind the check makes sense: if a fullscreen window opens
another window (e.g. a configuration dialog) it should not be put back
to normal layer. Thus the check is adjusted whether the new active
window is a transient to the fullscreen window. Thus the intention is
still the same, but does not cause the problems.
As the code now does not need to differentiate between X11 and Wayland
windows (group only on X11) the Client specific implementation is
removed and the method unvirtual'ed.

When an X11 window is raised to fullscreen it gets set to active layer.
When another window gets activated then it goes back to normal layer.
But when a window of the same group gets activated the fullscreen window
stays in the active layer. Due to that it is not possible to raise other
windows above the fullscreen window.
This just adds a test case exposing the problematic area.

Summary:
So far KWin used the window title provided from the window directly
without any sanitizing. This could result in broken window decorations
if the title included line breaks. Those were passed to the decoration
and depending on the way how the decoration renders the title, it could
result in visual breakage.
Having line breaks in a window title doesn't make sense. Given that KWin
now simplifies the title when copying it to it's own structure. This
also ensures that the title passed to e.g. task manager does not have
any line breaks on Wayland.
