Used to be the QQuickView implementation for the tabbox. As it's now
controlled through opening windows from QML directly it's no longer
needed or used anywhere.
No longer needed in a Plasma2 world as the components have a thumbnail
component, so the hack to go over KWin to render the thumbnails is no
longer needed.

By not using a QQuickView it becomes possible to just use a
PlasmaCore.Dialog or a Quick.Window in the TabBox qml and thus it's
possible to simplify the qml code.
To support this a new SwitcherItem is introduced and exported to QML.
It's a simple QObject providing all the properties which used to be
exported to the root context. A declarative TabBox is expected to
use one of these items. The C++ side finds the Switcher and for that
supports the case that the SwitcherItem is the rootItem or a child
item.
A declarative TabBox has also to create a QQuickWindow, e.g. a
PlasmaCore.Dialog. The visibility of that window should be controlled
through the visible property on the SwitcherItem. The underlying C++
implementation assumes that a TabBox only uses one window (it needs to
get destroyed once it's hidden and included in highlight windows).
Thanks to this change it's no longer needed to reload the TabBox
whenever it gets shown or the alternative TabBox gets shown. Instead
the same QML script can get reused. Other created switchers are ignored
as the visible property won't be changed to true.
The modalActionSwitch was used to disable all of KWin's actions during
Alt+Tab. This is not needed as Alt+Tab uses a keyboard grab and thus
no action will be triggered anyway.
Furthermore the functionality had been broken for years. The effects
use an own KActionCollection so their actions aren't considered and
neither the scripts.
Client used to have dedicated methods for different icon sizes instead
of combining all pixmaps into one QIcon. This resulted in various parts
of KWin having different access to the icons:
* effects only got one pixmap of size 32x32
* decorations only got the 16x16 and 32x32 pixmaps combined into a QIcon
* tabbox could request all icon sizes, but only as pixmap
Now all sizes are available in one QIcon allowing to easily access the
best fitting icon in a given UI.
It's basically a run of the port-cmake.sh script in here, mostly the changes
are the following:
- Using KF5::* targets
- Using the proper macros, following recent developments in frameworks
Not the best solution, but at least TabBox works each time it's invoked.
It doesn't make much of a difference as the QML is reparsed anyway at
each show.
Our back shortcut is registered as Alt+Shift+Backtab but our converted
Qt key coming into the test method is Alt+Shift+Tab. The logic so far
made this always fire for the normal Alt+Tab shortcut as at some point
the Shift modifier gets removed to do the test.
To handle it properly we first have to extract all the modifiers to just
get the key. If the key is Tab, we replace it with Backtab, combine it
with the extracted mods so it will be Alt+Shift+Backtab which matches
the registered shortcut.
The existing backtab solution can probably be removed and is clearly
wrong as it uses the keys as flags which they aren't.
There used to be an own action collection in KDE 3 times for the
block global shortcuts shortcut. But the code ws disabled and by
that I didn't see it during removing the global shortcuts blocking.
And it explains why the global shortcut blocking didn't work.
All the globalShortcutChanged slots are removed and replaced by a
generic one for the new signal by KGlobalAccel.
The define for creating the shortcut is dropped and replaced by a
templated function creating connections through the new connect
syntax.
Straight forward port. Note: this is currently crashing deep down in
QtQuick. To circumvent the crashes it helps to disable the property
highlightFollowsCurrentItem in the listviews. This solves the problem
that QtQuick crashes on first loading. Unfortunately it still crashes
if one tries to invoke TabBox for the second time.
AbstractThumbnailItem inherits from QQuickPaintedItem using QPainter to
do the fallback painting of icons.
The scene is adjusted to get the information from QQuickItem instead of
QDeclarativeItem. Clipping got a little bit more complex as the clip
path does not exist any more. To get it right the ThumbnailItem needs to
specify the parent it wants to be clipped to with the clipTo property.
E.g.:
clipTo: listView
The scene uses this clipTo parent item to correctly calculate the clip
region. Also the ThumbnailItem needs to have clipping enabled.
Note: this commit currently breaks TabBox as the qml and view are not
yet adjusted. In scripting the export of the item is disabled, but any
qml script using a ThumbnailItem would obviously also fail.
This happens because some distros ship broken installations
of KWin and KWinActive, but could also appear to QML hacking users

Not sure why kdeclarative gets its own subdir, nor why
there is no CMake module to to add it to the include dirs
on find_package, but this matches what plasma-framework
does at the moment.
Button Press/Release do no longer fall through to motion notify as
there is no shared mouse event in xcb. Also the methods in Effects and
TabBox are adjusted to process only button press/release or motion
notify.
ScreenEdges are no longer checked for button press/release. They don't
interact on button press/release so there is no need to check it.
* "" needs to be wrapped in QStringLiteral
* QString::fromUtf8 needed for const char* and QByteArray
* QByteArray::constData() needed to get to the const char*
Let KDeclarative::setupBindings() add the import paths: it too takes
paths from KGlobal::dirs()->findDirs("module", "imports"); it adds paths
in the correct (reverse) order [1].

The existing desktop switcher becomes the first available layout called
"informative". For both variants of desktop switchers a new config key is
introduced to define the desktop switcher layout.
Desktop layouts are installed into a different directory than window
switcher layout and use a different service type.
For the moment it's basically a hidden config option as there are no
further layouts yet.

Following the approaches of other split out functionality Screens is a
singleton class created by Workspace.
The class takes over the responsibility for:
* screenChanged signal delayed by timer
* number of screens
* geometry of given screen
* active screen
* config option for active screen follows mouse
The class contains a small abstraction layer and has a concrete subclass
wrapping around QDesktopWidget, but the idea is to go more low level and
interact with XRandR directly to get more detailed information.
All over KWin the usage from QDesktopWidget is ported over to the new
Screens class.

All activities related code moves into new singleton class Activities.
This class gets only included into the build if the build option is
enabled which means there are less ifdefs all over the code and it also
handles better the moc doesn't like ifdef case.
The class holds the list of open and all activites, the current and the
previous activity and the KActivities::Controller. It also emits the
signals for any activities related changes.
Workspace still contains some activities related code. That is the
adjustment on change of current activity. Nevertheless the code looks
much cleaner now and does not contain the confusing naming conflict with
takeActivity() which existed before.
In all the places where Activities got used the code got adjusted and
quite often the ifdef got added with a fallback for the disabled case.
Many headers included KLocale to use i18n and co. But those methods are
defined in KLocalizedString and not in KLocale.
With KF5 klocale.h does no longer include KLocalizedString causing lots
of compile errors.
To support this feature the DesktopModel is turned into a tree model with
the desktops on the root level and the Client's at the next level.
In the view a VisualDataModel is used which kind of supports a tree model
by setting the root index. A list view is added underneath all the
desktops showing the icons of the windows on the desktop one switches to.

The new class FocusChain manages two different kind of focus chains.
First of all there is a most recently used focus chain which is primarily
used for TabBox.
Then there is one focus chain per virtual desktop. These chains are used
to determine which Client needs to be activated when e.g. switching to a
virtual desktop.
The individual chains are implemented as a simple QList of Client* with
the most recently used Client as the last element. That way one can see
it as a LIFO like structure.
The desktop focus chains are internally represented as a hash with the id
of the virtual desktop as the key and a list as described as the value.
FocusChain is a singleton which provides some methods to manipulate the
chains and to get a specific Client for a task (e.g. TabBox).
While splitting out the code some unused code inside TabBox got removed
as well as some activities related code (windows cannot be moved while
switching activities).

Use xcb to create and manage the X11 backend of Outline. In addition the
used background pixmaps are rendered with XRender instead of using a
QPainter on a QPixmap. This is done because QPixmap is no longer bound to
an X Pixmap.
To create the XRender Picture the available functionality from
kwinxrenderutils is used. To be able to use it in KWin core the compile
option to build without XRender is removed for kwinxrenderutils, but
still supported for effects.
Obviously the port to XCB is not complete as xremderutils itself is still
on XLib.

In effects it's obvious that compositing is enabled, so specifying the
translucent element is no problem.
In tabbox a context property "compositing" is injected which decides
whether "translucent" or "opaque" elements should be used. Here the
translucent elements are only used if the Blur effect is available - for
this a new Effect::Feature Blur is introduced and in addition it is
tested whether the theme provides the translucent element.
Also the masking is adjusted to ensure that only the shadow is not
blurred.
Reason for this change is that Plasma theme seems not always to pick up
whether compositing is used when used from inside KWin. It does not cover
the Desktop Change OSD which uses PlasmaCore.Dialog and there we cannot
(yet) inject that we use compositing.
Overall I'm quite unhappy with this patch and I do hope we can fix it in
the proper place in the lifetime of 4.10 and revert this patch.

due to plasma change, shadow is not included by default, hence kwin
tabbox need to handle shadow by itself, and due to kwin is compositor
and have shadow as effects, it's not a good idea to use X property to
pass shadow from kwin to X and to kwin. This change use the old way to
draw shadow side the tabbox, and partly move the blur region setting to
qml.
REVIEW: 108243
Most recently used virtual desktop chain is only used in the context of
TabBox and therefore moved into this namespace. KWin uses one desktop
chain for each activity. This is mapped by having multiple DesktopChains.
In addition there is a DesktopChainManager which contains all those
chains which are identified by a QString.
The manager gets connected to the signals emitted by VirtualDesktopManager
for changes in virtual desktops and to signals related to Activities
emitted by Workspace. This means the manager is rather generic as it does
not depend on any other components.
The ownership for virtual desktops is moved from Workspace into a new
VirtualDesktopManager. The manager is responsible for providing the count
of virtual desktops and keeping track of the currently used virtual
desktop.
All methods related to moving between desktops are also moved from
Workspace to the new manager, though all methods related to Clients on
Virtual Desktops remain in Workspace for the time being. This is to have
the new manager as independent from KWin core as possible.
An rather important change for the handling of virtual desktops is that
the count and the id of a desktop is now an unsinged integer instead of
an integer. The reason for that is that we cannot have a negative count
of desktops as well as it is not possible to be on a desktop with a
negative identifier.
In that regard it is important to remember that a Client can be on a
desktop with a negative identifier. The special value for a Client being
on all desktops is handled by using -1 as a desktop. For the time being
this is not adjusted but instead of comparing the virtual desktop ids one
should prefer to use the convenient methods like isOnDesktop and
isOnAllDesktops. This would allow in future to internally change the
representation for on all desktops.
Escaping is performed in the model instead of the UI as each of the QML
files needed to be fixed and it is likeley that the issue would come up
again. In the model it's hopefully fixed for good.

If the start Client is not part of the focus chain the call to
nextClientFocusChain() cannot return the Client again. So the loop break
condition is never reached and as the focus chain is not empty the call
always returns a not null Client which means KWin is caught in an endless
loop.
This change checks that the starting Client is in the focus chain and if
not the first Client of the focus chain is used.

So far the first Client to be shown in the list (that is the
currently active window) was inserted as the last client into
the list by prepending it to the list.
This meant that if another Client actually blocks the inclusion
of the currently selected Client (e.g. only one window per app)
the currently active Client never got included in this list.
This change ensures that the recently used model switching has
the starting Client as the first Client in the list and also
simplifies the code.
Stacking order switching mode is not adjusted as it seems rather
broken, like the comment already says.

The method was missing a check whether the weak pointers in the
internal list got deleted. This could in very unlikely cases
lead to a crash.
In order to verify that adding the null pointer check fixes the
crash a unit test is added to simulate the situation of a
pointer being deleted. This required to add a mock a few
classes of TabBox. A MockTabBoxHandler and MockTabBoxClient are
added implementing the specific interfaces. The DeclarativeView
is completely mocked to make the linker happy. Including the
actual implementation is not possible as it pulls in half of
KWin core.
