Vlad Zahorodnii 1fb9f6f13a Switch to SPDX license markers
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.

Vlad Zahorodnii 9d4a32596c Drop some custom list typedefs
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.

Martin Flöser a0b482cbab Introduce a command line option to disable any kind of global shortcuts
Summary:
This command line option is useful for KWin in embedded use case. That
is when KWin is just used as a compositor for one application instead of
a complete desktop environment. In such a setup global shortcuts are not
wanted and interfere with the application. E.g. one does not want Alt+F4
to close the window, that would render the system unusable.

This change introduces a command line option and disables the following
event filters and spies:
 * global shortcuts
 * modifier only shortcuts
 * terminate session
 * virtual terminal switching
 * screen edges

KGlobalAccel still gets inited, otherwise the (non-functional) binary
would be launched when KWin registers it's global shortcuts.

Test Plan:
New test added based on existing tests for the global
shortcuts, ctest passes

Martin Gräßlin 229be65e40 Improve the escape key handling for breaking constrained pointers
Summary:
So far KWin started to filter out the escape key as soon as it gets
pressed. This was done by unsetting keyboard focus. The idea was to
reset keyboard focus when it is only a short press and that then the
keyboard state is correct for the application. But in practice this
does not work. The only application currently supporting pointer
constraints (Xwayland) does not do anything on a key which is pressed
when gaining keyboard focus. The result is escape not working in
pointer constrained Xwayland windows.

This change addresses this problem by changing the interaction to only
unset keyboard focus when our break constraints condition is met. This
should also result in the application not handling the key release, but
it means it gets the key press. Unfortunately I don't have a good way
to test.

Martin Gräßlin a039c2760f Handle modifier updates in the same sequence as Wayland does
Summary:
Consider the case that capslock gets pressed and released.
In the case of Weston we have a sequence of:
 1. Key press event
 2. Modifier changed event
 3. Key release event
 4. Modifier changed event

KWin however used to send the events in the following sequence:
 1. Modifier changed event (on key press)
 2. Key press event
 3. Modifier changed event (on key release)
 4. Key release event

It looks like Xwayland is not able to properly process the sequence
sent by KWin. And in fact KWin's sequence is wrong as it sends a state
which does not match. We report that the caps lock is pressed in the
modifiers prior to the application getting informed about the key press
of caps lock.

This change aligns KWin's implementation to the behavior of Weston. The
main difference is that when modifiers change Xkb internally caches the
serialized modifier states. And KeyboardInputRedirection just forwards
the modifiers to KWayland::Server::SeatInterface once the processing has
finished. SeatInterface ignores the forwarding if no states changes, so
it is fine to do it that way.

BUG: 377155

Test Plan:
Not yet tested with an affected Xwayland as I only have 1.18 and the
problem started with 1.19. But verified the sequence of events with WAYLAND_DEBUG
and caps lock stil working in QtWayland clients and Xwayland 1.18

Martin Gräßlin 65ddd32d1a Split modifier only handling into a dedicated InputEventSpy
Summary:
The functionality regarding triggering modifier only shortcuts is moved
out of Xkb - where it doesn't belong to - and is turned into an input
event spy listening for the changes it is interested in. Previously
the state got queried by asking e.g. for the pressed buttons, now it's
tracked directly.

The X11 side needs a larger change due to that as now pushing the events
into Xkb does not trigger modifier only shortcuts any more. Instead the
"normal" way through the platform API needs to be used which triggers the
processing of filters and spies.

The problem here is that our redirections only process events if they are
inited and that only happens on Wayland. We cannot call init on them as
that would create all the Wayland filters and spies and processing would
probably break. As an intermediate solution the spies are now processed
and there we know that it won't matter. A future solution would be to
remove the init checks completely and just send through both filters and
spies and ensure that on X11 only the supported ones are loaded.

Martin Gräßlin 8d9c4acf4d Provide kxbk config through kwinApp
Summary:
So far KWin parsed the kxbkrc at multiple places (once in Xkb, once
in KeyboardLayout). This is now replaced by one KSharedConfigPtr hold
by kwinApp, just like the normal kwinrc. The KSharedConfigPtr is now
passed to Xkb.

As a nice side effect this makes it easier to test keyboard layout
changes as we can now properly mock the keyboard configuration. Thus
this change also comes with an autotest for loading keyboard layout
configuration. This is becoming more and more a need as we start
getting bug reports for layout specific issues like global shortcuts
not working with Greek layout.

Martin Gräßlin eb92477210 Split Keyboard Repeat handling into a dedicated InputEventSpy
Summary:
So far the keyboard repeat handling was triggered directly from
KeyboardInputRedirection::processKey. With the introduction of
InputEventSpies it is no longer required to be done like that, we can
split it out into a dedicated spy.

This means that processKey only has to care about processing the key
and allows us to better extend in future. So far keyboard repeat is
only functional for libinput based platforms. But it should also be
possible to use it in nested setups. By splitting it out we can
prepare for that.

Martin Gräßlin fe561c5c7d Add a basic SNI for keyboard layout
Summary:
On X11 the SNI for keyboard layout is provided by the keyboard kded.
On Wayland that kded has no real access to the layouts and cannot
properly implement switching. Given that it's better to integrate the
SNI directly in KWin.

The implementation of the SNI is largly based on the existing SNI from
plasma-desktop/kcms/keyboard. The implementation so far supports:
 * Switching to next layout on toggle
 * Presenting all layouts in a context menu
 * Switching to a specific layout through the context menu
 * Opening the keyboard layout configuration module
 * scroll on SNI to switch layout
 * config option whether to show the SNI

Not yet supported are:
 * flags and/or short text for the layouts

The last point needs more explanation. On X11 the layout name is
something like "de" or "us". This can be directly mapped to a flag and
can be added as a short note.

Xkbcommon does not provide this information directly. Instead it provides
us the full name of the layout, e.g. "German" or "English (us)". There is
no way in the API to go from "German" to "de".

Instead we need to parse the evdev.xml file to gather all information
about layouts. This is already done in the keyboard kcm to configure
layouts. The implementation needs to be split out into a small helper
library.

Martin Gräßlin 5a87fa3f92 Support modifier-only-shortcuts when capslock is on
Summary:
So far we didn't trigger modifier-only-shortcuts when capslock was
enabled. In fact we even ensured that the shortcuts did not trigger.
This seems not to be what our users expect. Meta should still trigger
if capslock is on.

This change modifies the logic to determine which modifier is currently
pressed by using the modifiersRelevantForGlobalShortcuts. The difference
to the "normal" modifiers is that this excludes capslock from modifiers
and excludes consumed modifiers. The latter is not really relevant as
modifier-only-shortcuts do not trigger if multiple keys are pressed,
which is required to have a modifier consumed.

Martin Gräßlin a3be3e8e80 Translate the layout name when passing to layout change OSD
Summary:
Xkbcommon does not localize the layout names. We always get the US
English variant. KWin so far passed the strings from xkbcommon directly
to UI visible parts such as the Plasma OSD. This results in not
translated elements in our UI.

As I figured out today the translations exist in the domain
xkeyboard-config. Passing the strings from xkbcommon through this domain
gives us translated layouts.

Unfortunately the xkeyboard-config is not installed by default on all
distributions. E.g. on ubuntu/neon one needs to install xkb-data-i18n
to have the translations available.

Martin Gräßlin d6c0a5414e Split implementation of keyboard layout handling into a dedicated class
Summary:
So far the implementation of keyboard layout handling was split between
KeyboardInputRedirection and Xkb. KeyboardInputRedirection registered
the global shortcut and did the handling for layout switch and config
changes. Xkb did the notification on layout change.

Layout changes can nowadays be detected through an InputEventSpy. It
can only happen after a key change or an explicit layout switch. Thus
it does not need to be in Xkb anymore which allows to reduce Xkb to
only care about the Xkb keymap and state tracking.

This change introduces a new class KeyboardLayout which is an
InputEventSpy and takes over the task of the layout change notification
from Xkb and the layout management from KeyboardInputRedirection. Thus
everything related to management of keyboard layout is together in one
class.

This allows in future to add unit test to it (requires further cleanup
of Xkb to be able to use it and drop the InputRedirection dependency) and
opens the possibility to also take over keyboard layout management on X11
for the Plasma desktop.

Martin Gräßlin 84e3308149 Introduce an InputEventSpy for processing input events
Summary:
So far KWin's input event processing is mostly based on
InputEventFilters. A filter can - as the name suggest - filter out an
input event from further processing. Our code shows that this is not
sufficient for all input event processing.

We have several areas inside KWin where we need to have access to all
input events, where the processing needs to happen on all events and
filtering is not allowed. This results in sub-optimal code which has
classes which know too much and do too much.

Examples:
 * key-repeat handling done in KeyboardInputRedirection
 * Layout change OSD in Xkb
 * modifier only shortcuts in Xkb
 * emitting signals for Cursor class in KeyboardInputRedirection

Also there are misuses of the InputEventFilters and internal API
 * DebugConsole keyboard state (uses wrong information)
 * DebugConsole input events tab (uses Filter, should be a spy)

This change introduces the API needed to fix these problems. It
introduces an InputEventSpy which is modelled after the InputEventFilter
with the difference that it has only void messages and uses the KWin
introduced event classes.

The spies are always processed prior to the filters, thus we know it can
have all events.

filters. The std::function is supposed to be generated with a std::bind

Martin Gräßlin 0c5ca405cc Implement support for pointer constraints
Summary:
There are two types of constraints supported:
1. Pointer confinement
2. Pointer locking

In the case of confinement the pointer is confined to a given region of
the surface. This is comparable to general operation where the pointer
is confined to the screen region.

In the second case the pointer gets locked. That means it cannot move at
all. No further position updates are provided, only relative motion
events can go to the application. There is a hint about cursor position
update on unlock which is not yet implemented in KWayland::Server, thus
also not in this change.

The implementation in KWin grants the requests for pointer constraints
when the pointer enters the constrained region, either by pointer
movement or by e.g. stacking order changes. There is no confirmation
from user required to enter that mode. But we want to show an OSD when
the pointer gets constrained, this is not yet implemented, though.

Breaking an active constraint is relatively easy. E.g. changing the
stacking order will break the constraint if another surface is under the
cursor. Also (in case of confinement) moving the pointer to an
overlapping window breaks the confinement. But as soon as one moves the
pointer back to the window a constraint might get honoured again.

To properly break there is a dedicated event filter. It listens for a
long press of the Escape key. If hold for 3sec the pointer constraint is
broken and not activated again till the pointer got moved out of the
window. Afterward when moving in the pointer might activate again.

The escape filter ensures that the key press is forwarded to the
application if it's a short press or if another key gets pressed during
the three seconds. If the three seconds way fires, the later escape
release is not sent to the application.

This basic interaction is also ensured through an added auto test.

This change implements T4605.

Martin Gräßlin 421824b654 Workaround xkbcommon behavior concerning consumed modifiers
Summary:
If a key could be turned into a keysym with a modifier xkbcommon
considers the modifier as consumed even if not pressed.
E.g. Alt+F3 considers alt as consumed as there is a keysym gnerated with
Ctrl+Alt+F3 (vt switching).

This change tries to workaround the problem by ignoring the consumed
modifiers if there are more modifiers consumed than active. It's
possible that this will create regressions for other shortcuts - we need
to test it in the wild. Although this might cause regressions I'm aiming
for Plasma/5.8 branch with the change. It only affects Wayland and fixes
quite important shortcuts from window manager perspective (desktop
switching (ctrl+f1 to ctrl+f4), desktop grid (ctrl+f8), present windows
(ctrl+f9, ctrl+10), cube (ctrl+f11), user actions (alt+f3), close window
(alt+f4)). If it causes regressions they need to be fixed as well in the
Plasma/5.8 branch.

A new API entry point for xkbcommon was proposed, but is not yet merged
and there is no release with it yet. Once that is available the
workaround should get removed and replaced by the new API call.

Martin Gräßlin 3bc6089394 Only repeat one key
Summary:
So far KWin tried to repeat all pressed keys which should repeat. But
this is not how X11 and e.g. QtWayland handle it. There only one key -
the last one which got pressed - repeats. And this makes sense as the
key is used to generate a keysym and that one KWin caches. Thus the
logic so far resulted in incorrect keysyms to be generated during the
repeat. E.g. pressing a, pressing b, releasing b would repeat b instead
of the hold a as b was the last generated keysym.

This change addresses this problem and let's only one key repeat at a
time. When the currently repeating key gets released the repeat timer is
stopped and other hold keys won't repeat any more. This also matches the
behavior of X11 and QtWayland.

Martin Gräßlin 4235871667 Remove not-wanted modifiers prior to evaluating global shortcuts
Summary:
When triggering global shortcuts we are more interested in the hold
keys than the currently active modifiers. E.g. capslock should not
be seen as "shift is hold". Similar we need to remove consumed
modifiers. Shift+5 is % and not Shift+% - the shift modifier is
consumed and needs to be removed from shortcut evaluation.

To support this we need to have the actual state directly from
xkbcommon. Thus a new method is added which exposes the modifiers
relevant for global shortcut matching. In addition on every key press
all consumed modifiers are calculated and kept so that they can be
used for shortcut matching.

In addition a workaround is added for Backtab. Similar workaround
exists in kglobalaccel for X11. The problem is that our shortcuts are
stored incorrectly: Shift+Tab instead of Backtab. Thus a mapping back
is required. To make everything worse KWin registers the wrong key
sequence "Alt+Shift+Backtab" which doesn't make any sense and is
broken on X11 at least.

The workaround supports both special cases. The one for Backtab should
be turned into Shift+Tab and also KWin's special case of adding shift
to backtab.

Martin Gräßlin a98a1b1376 Support compose key in xkbcommon integration
Summary:
The Xkb class now creates a compose key table and a state object and
feeds all key presses through the compose state machine.

Xkb now tracks the latest keysym which is provided through new method
currentKeysym. This is now used when creating a QKeyEvent instead of
passing the key code to the xkb state. With that the keysym can also
be updated through the compose state system.

This only affects KWin internal usage where text is composed, e.g. the
present windows effect filter. Wayland clients do not gain compose key
support, though.

Minimum xkbcommon version raised to 0.5 as compose key support is new
in that version.

Test Plan: Enabled compose key support in keymap and verified through DebugConsole

Martin Gräßlin 7d7bbcc56a Only trigger keyboard layout OSD if KWin manages input
Summary:
On platforms where KWin does not manage input, that is does not
use libinput, KWin gets the keyboard layout from another place, e.g.
the X server. In that case KWin should of course not trigger the
layout changed OSD if KWin thinks (for whatever reason) that the
layout changed.

Martin Gräßlin ec98f498e8 Ensure modifier locks and latches don't trigger the mod only shortcut
Summary:
If caps lock is on the shift key should not trigger. Similar pressing
caps lock should neither on activation press nor on deactivation press
trigger the shortcut. Related to that are latched modifiers aka sticky
modifiers: if the modifier is still on after releasing the key the
shortcut should not trigger. We must assume the user wanted to use the
modifier to activate the modifier, not to activate the shortcut.

This change ensures that we don't track for modifier only shortcuts if
a modifier is active before press or after release.

The added test case demonstrates for caps lock, latched modifiers is
currently still untested. (Needs a way to mock it).

Test Plan: See test case for caps lock.

Martin Gräßlin ea22b8f15d Introduce env variable KWIN_XKB_DEFAULT_KEYMAP to force default layout creation
Summary:
The Xkb class loads keyboard layouts from the users configuration. This
makes tests fail locally if the user has a layout which behaves
differently to the one the test expects. E.g. on a German layout the
right alt key is different to the one of US layout.

In order to have a more stable test base the env variable
KWIN_XKB_DEFAULT_KEYMAP forces the loading of the default keymap, thus
tests have a common layout set.

Martin Gräßlin 2c333417fa Support modifier only shortcuts on X11
Summary:
With this change KWin/X11 reuses Wayland's modifier only shortcut
architecture. The XInput2 event filter also listens for
 * XI_RawKeyPress
 * XI_RawKeyRelease

Those events are also reported if another X11 client grabs keyboard
input. Thus KWin gets all key events, just like on Wayland.

All key events are then sent through the Xkb class which performs the
mapping from key codes to key syms and is able to detect whether the
modifier got pressed/released without another key being pressed.

This change will require a few follow up changes, which are required
also for Wayland:
 * ignore if another input device got interacted (e.g. mouse press,
   touch screen, scroll, etc)
 * use the layout from XServer instead of using our own (needed on
   Wayland in nested setup)

The biggest disadvantage of the change is that it triggers a wake
up of KWin on every key event. But as KWin already listens to all
pointer events that's not a big difference and normally a key event
will wake up the compositor any way.

Martin Gräßlin bd58d7792f Don't trigger modifier only shortcuts if pointer interaction
Summary:
If the user clicked a pointer button or scrolled a pointer axis the
held modifier was most likely intended to modify the pointer event.
Thus the modifier only shortcut should not be triggered.
