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is obsolete.
This is a little helper that can be very convenient with our transition
from int-based screen ids to AbstractOutput.
As is, the main issue with int screen ids is that they are extremely
dynamic.
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.
toplevel.h is included in many places. Changing virtualdesktops.h may
trigger rebuild of all kwin.
With this change, only cpp files that use virtualdesktops.h will need to
be recompiled.
Once in a while, we receive complaints from other fellow KDE developers
about the file organization of kwin. This change addresses some of those
complaints by moving all of source code in a separate directory, src/,
thus making the project structure more traditional. Things such as tests
are kept in their own toplevel directories.
This change may wreak havoc on merge requests that add new files to kwin,
but if a patch modifies an already existing file, git should be smart
enough to figure out that the file has been relocated.
We may potentially split the src/ directory further to make navigating
the source code easier, but hopefully this is good enough already.
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.

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:
Qt has its own thing where a type might also have corresponding list
alias, e.g. QObject and QObjectList, QWidget and QWidgetList. I don't
know why Qt does that, maybe for some historical reasons, but what
matters is that we copy this pattern here in KWin. While this pattern
might be useful with some long list types, for example
QList<QWeakPointer<TabBoxClient>> TabBoxClientList
in general, it causes more harm than good. For example, we've got two
new client types, do we need corresponding list typedefs for them? If
no, why do we have ClientList and so on?
Another problem with these typedefs is that you need to include utils.h
header in order to use them. A better way to handle such things is to
just forward declare a client class (if that's possible) and use it
directly with QList or QVector. This way translation units don't get
"bloated" with utils.h stuff for no apparent reason.
So, in order to make code more consistent and easier to follow, this
change drops some of our custom typedefs. Namely ConstClientList,
ClientList, DeletedList, UnmanagedList, ToplevelList, and GroupList.
Test Plan: Compiles.

Summary:
Currently kwin opens a second ICE connection to ksmserver in order to
tell the state of kwin's whether we're logging out and saving clients or
not.
This requires that kwin launches after ksmserver to have the connection
which is a dependency I want to break.
Practically this code is already ksmserver specific as it relies on some
custom code that sends the first saveState request to kwin first.
Instead we can replace it with a bespoke IPC over DBus and siplify the
code both end. This will allow several other future enhancements that we
want with regards to handling the session state, as well as make an
effort platform agnostic session management, as well as cleaning up some
complex code.
Ksmserver calls into kwin, rather than having kwin watch ksmserver state
to allow us make sure it's race free.

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:
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:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.
This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).

So far we were following a bit unique and rare doxygen comment style:
/**
* Contents of the comment.
**/
Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer
more traditional doxygen comment style, i.e.
/**
* Contents of the comment.
*/
Reviewing such changes has been a bit frustrating for me (so selfish!)
and for other contributors.
This change switches doxygen comment style in KWin to a more traditional
style. The main reason for doing this is to make code review process easier
for new contributors as well us.

Summary:
This is used by GTK clients to know whether to draw as though they have
focus or not. Whilst it's most visible for CSDs headers, use of the
active/inactive palette (or backdrop class in GTK terms) applies
everywhere.
Rationale of the flag is to allow the WM to hint visual states without
giving input, i.e so you can hint that the parent of a modal dialog
should be shown as active. Though kwin only sets it on the truly active
window to match the behaviour our other windows follow.
BUG: 398832
I expect this to be potentially controversial as it's new code in X11,
so in advance:
* Unlike GTK_FRAME_EXTENTS, it is part of the specificiation (albeit
1.4) even i3 supports it.
* It does fix a real world issue
* It's only 2 lines (plus trivial boiler plate in kwindowsystem)
* It's in code path that we rely on for our existing code
* If there's a situation where this does break, the worst that will
happen is a client gets a visual hint to have focus incorrectly, which
ultimately is the same as the current state

Summary:
Commit 5d9027b110 introduced a regression in TabBox by using the generic
framework inside KWin to test for same application. What I did not
consider was that the code in TabBox was "broken by design". It didn't
use the generic check as that is too strict and considers windows from
different processes as not belonging to the same application. But this
is not wanted in the case of TabBox.
On the other hand the change itself is an improvement to also support
Wayland in a better way and not have special handling situations. Thus
just reverting would not help.
Instead this change addresses the problem by extending the internal API
and to allow more adjustements. So far there was already an
"active_hack" boolean flag. This is extended to proper flags with an
additional flag to allow cross application checks.
The checks in Client which would filter out different applications check
for this flag and are skipped if set. In addition ShellClient also adds
support for this flag and compares for the desktop file name.
Thus we get in TabBox the same behavior as before with the advantage of
having a better shared code base working on both X11 and Wayland.

Summary:
So far KWin always updated the active window property even if the actual
window id hasn't changed. E.g. if a Wayland window was active and another
Wayland window gets activated the window id was and stays 0.
Nevertheless KWin updated the property causing wakeups in X server and
any application listening to property changes on the root window.
Futhermore this situation is an information leak: we leak when a Wayland
window gets activated to X11.
To solve this problem RootInfo caches the active window id and only
updates if it changes.
Test Plan:
Verified with xev -root that the active window does not get
updated needlessly.

QDialog or at least QMessageBox does this and I doubt Lubos' idea was to
"allow focus stealing if the client nags enough" - switching the VD is a
major interrupt and prevented when a new window shows up.
It should not be possible to stomp on ground and then receive
focus - notably not on the other desktop.
I assume the original idea was to let clients distribute focus *inside*
across virtual desktops, maybe also permit when no client was active,
but hardly otherwise.

AbstractClient now also supports mainClients, so we can do the
fullscreen window check on setActive in a general way. This ensures
that we do get proper stacking changes for activating fullscreen
shell clients.
This fixes yet another regression from the transient refactoring.
The passed in client might be null, so we need a nullptr check. There
are several already in that code.
Was tricky given that I removed a cast there.
AbstractClient::mainClients is virtual and overriden in Client,
allMainClients has only a common implementation in AbstractClient.
In activation.cpp we still need one case where a temporary ClientList
needs to be constructed. Once transients are fully migrated that should
be removable again.
othrwise closing a keepabove or desktop group
window would activate some random window and break
the state as a side-effect

instead of "just" the direct transient.
Reason is that many windows set dialogs transient
for an entire group (eg. all their document windows)
If there's only one window, that is equivalent to choosing
the direct transient leader.
Originally I wanted to allow this for any amount of
leaders and picked the first one, but that means if
you open 2 kwrite windows (from one PID!) and an
open dialog for kwrite #2 and close the latter,
the focus would be passed to kwrite #1
-> The focus chain is the better choice here.
(One could look up all leaders in the focus chain
OR the stack and use the most recent/top one,
but that's probably voodoo)
