3259d5e113 Cancel popup if the user clicked window decoration of parent window
Summary:
So far the window decoration was not considered and e.g. right clicking
the window decoration resulted in two open popups - one by KWin and one
by the application. This change addresses the problem by ensuring the
popup gets cancelled if the decoration is clicked. It's considered not
being part of the window.

Test Plan: Added test case which fails without the change

1193b0da77 Initial support for popup window handling
Summary:
So far KWin did not properly handle popup windows. That is when a popup
surface got created and a click outside the surface happened KWin did not
send out the popupDone Wayland event.

This change makes KWin aware of whether a surface is a popup and tracks
through a new PopupInputFilter whether there are popup windows. In case
there are popups the new filter waits for mouse press events and cancels
the popups if the press does not happen on any surface belonging to the
same client. To quote the relevant section of the Wayland documentation:

    The popup grab continues until the window is destroyed or a mouse
    button is pressed in any other client's window. A click in any of the
    client's surfaces is reported as normal, however, clicks in other
    clients' surfaces will be discarded and trigger the callback.

So far the support is still incomplete. Not yet implemented are:
 * support xdg_shell popup windows
 * verifying whether the popup is allowed to be a popup
 * cancel the popup on more global interactions like screen lock or
   kwin effect

0bb587dcb9 Ensure PointerInputRedirection::processMotion finishes prior to warping
Summary:
Consider the following situation: we have three InputEventFilter linked
in the sequence A - B - C.

The input filters are processing pointer motion events. The expected
behavior is that the new motion is processed in the sequence
   A -> B -> C

So far this did not work correctly if the pointer gets warped during the
processing. If e.g. filter B warps the pointer we get a motion sequence:
   A (1) -> B (1) -> A (2) -> B (2) -> C (2) -> C (1)

The filters following the one warping the pointer get first the newer
than the older position. This is obviously wrong. Unfortunately it is not
just a theoretical condition, but a condition happening when interacting
with the screenedges, which warp the pointer.

This change introduces a PositionUpdateBlocker in
PointerInputRedirection::processMotion to ensure that a processMotion
call finishes prior to the next update. If the PositionUpdateBlocker is
blocked the new position gets scheduled and processed once the
PositionUpdateBlocker gets destroyed.

With this we get the expected sequence for B warping pointer:
   A (1) -> B (1) -> C (1) -> A (2) -> B (2) -> C (2)

This should hopefully improve the interaction with screen edges on
Wayland.

CCBUG: 374867

Test Plan:
Added an auto test demonstrating the issue of incorrect
ordering caused by screenedges. Prior to the change the test is failing.

c0b207a2b5 support for auto-hidden windows to resize
Summary:
auto hidden windows were shown again when their geometry
changed, this was done for being as easy as possible as
the unhide zone changed, but the behavior looked very
annoying as autohide panels with an self resize taskbar
would unhide themselves every time any window gets open
or closed.
This makes the edge keep track of
windows that can resize/move themselves while auto hidden

Test Plan:
a self-resizing autohidden panel with a taskbar in it doesn't auto unhide
anymore when a window is opened or closed.
the unhide area gets properly updated

8edd0336e6 Support creation of PlasmaShellSurface prior to ShellSurface
Summary:
So far KWin did not support the sequence:
1. Create wl_shell
2. Create PlasmaShellSurface
3. Create wl_shell_surface

KWin only supported the case that the PlasmaShellSurface is the last
thing to get created. This is rather limiting and can be considered a
bug. At least we had a QEXPECT_FAIL auto test for this situation. So
it was a known issue.

This change should make it easier to support the QtWayland changes in
Qt 5.8.

b16bd4147a Ensure the layoutChanged DBus signal gets emitted when changing layouts through DBus
Summary:
Unfortunately Xkb does not emit a signal when the keyboard layout
changes. Due to that we need to manually check in KeyboardLayout after
each action which could change the layout whether the layout changed.

This was not yet done for the case when the layout got changed through
the DBus interface. Resulting in the DBus signal not emitted.

This change addresses the issue by invoking the check for change after
changing the keyboard layout.

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.

7e89c51823 Add workaround for touch input offset for decorated windows
Summary:
If a Wayland window is decorated the decoration size was not considered
when passing touch points to the Wayland window. For pointer input this
is considered and implemented through the input transformation matrix
which KWayland::Server::SeatInterface accepts. This should also be done
for Touch. Unfortunately the frameworks version for Plasma 5.9 is already
tagged and done and we cannot depend on new API.

Thus this change tries to workaround by calculating the proper offset
through the input transformation matrix. It isn't nice but fixes the
problem for now.

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.

6a78bd45fe Fix syncing of geometry to internal window when using ::move
Summary:
The OnScreenNotification gets moved during its placement. This update
of the geometry did not get synced to the QWindow's geometry as it
should.

The reason for this is the rather special implementation of
AbstractClient::move. This just modifies the geom variable and does not
call into setGeometry at all. Instead a virtual doMove method is invoked
to inform the platform specific client implementation about the move of
the window. For a "normal" ShellClient that is fine - there is nothing
to do.

This change adds an implementation of doMove in ShellClient to sync the
geometry to the internal window. This is not yet enough to fix the
geometry of the OnScreenNotification. It gets placed with a
GeometryUpdatesBlocker in place causing the doMove never to be called.
Instead setGeometry is invoked again when the geometry updates get
unblocked. So far ShellClient did not do anything in this case. This
change ensures that at least the doSetGeometry method is performed again.

Test Plan: Added test case and manual testing of OnScreenNotification

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.

Summary:
A second interactive selection mode gets added to select a position on

window selection. Just that instead of returning a window, it returns a
QPoint.

This allows to pick a point on the screen which we need to screenshot
the screen under the mouse cursor and in future for color picking.

The screenshot effect provides two new dbus methods to (interactively)
select a screen or fullscreen. This allows spectacle to screenshot the
(full) screen with still having the user in control.

451bbb54dd [effects] Handle windowShown and windowHidden in fade effect
Summary:
For Wayland windows we can have a sequence of window unmapped
(windowHidden signal) followed by a windowClosed way later when the
application quits. This is for example the case with menus.

The result of this was that the fade out animation triggered when the
application quit showing all the already closed menus again.

This change implements a windowShown and windowHidden handler and
triggers the fadeIn/Out animation on it. If the window gets shown
again the existing fadeOut animation gets cancelled, so that it can run
again.

If a window gets closed for which a fade out animation has been run
already, it's not triggered again, thus ensuring that we don't see
zombie windows.

6bee7f4aac KillWindow support for Wayland windows
Summary:
AbstractClient gains a new pure virtual killWindow method and this gets
implemented in ShellClient.

ShellClient performs the killing by sending a term signal to the
process. This can only work if the client connected through the socket
and didn't get a socketpair fd passed. In that case the pid is KWin's
and KWin doesn't want to terminate. Thus this is special handled to
destroy the connection instead.

In case terminating the process has no effect, the connection gets
destroyed after five seconds.

The KillWindow is adjusted to operate on AbstractClient instead of
Client.

This implements T4463.

Test Plan: Killed windows and auto test
