Preparation step before splitting:
* adds project(KWIN)
* lists all KWin dependencies
KWin can be built standalone if cmake is run with:
-DKWIN_BUILD_OXYGEN=OFF
-DKWIN_BUILD_KAPPMENU=OFF
Oxygen because it needs liboxygen - for standalone clients/oxygen needs
to be moved out of KWin.
KAppmenu because it includes the DBus xml file.

This is a temporary solution to have less dependencies on
KDEBASE_WORKSPACE_SOURCE_DIR. Once kde-workspace is going to be splitted
this won't work, we need a proper way to find the dbus interfaces
provided by ksmserver.
Note: for appmenu the same problem exists, but doesn't affect us once we
are splitted as we can turn off the usage through a build option. So for
a splitted kde-workspace the appmenu dependency can just be temporarily
be removed.
Major new functionality is xkbcommon support. InputRedirection holds an
instance to a small wrapper class which has the xkb context, keymap and
state. The keymap is initialied from the file descriptor we get from the
Wayland backend.
InputRedirection uses this to translate the keycodes into keysymbols and
to QString and to track the modifiers as provided by the
Qt::KeybordModifiers flags.
This provides us enough information for internal usage (e.g. pass through
effects if they have "grabbed" the keyboard).
If KWin doesn't filter out the key events, it passes them on to the
currently active Client respectively an unmanaged on top of the stack.
This needs still some improvement (not each unmanaged should get the
event). The Client/Unmnaged still uses xtest extension to send the key
events to the window. So keylogging is still possible.
So far this new class is not yet doing much. The WaylandBackend forwards
the received pointer events to this InputRedirection class. From there
signals are emitted to inform internal areas about the changes first.
The events are currently forwarded to X through the xtest extension. This
will be removed in future. Input will be forwarded directly to the
surface which wants it (no matter whether X11 or Wayland).
In order to get all our UI being written in QML, the Outline for
compositing is ported to QtQuick. It creates a QQmlContext and
QQmlComponent and loads the (currently hardcoded) qml file. The context
gets to properties exported: outline. The outline property allows the qml
to get the geometry it should use. The QQmlEngine is used from Scripting
thus all general scripting properties are exported (e.g. workspace).
The qml script is expected to create a QQuickWindow as it's root item
and style it.
The qml file is stored in a new qml subdirectory. The idea is that each
of the qml types we have gets an own directory there and for each
implementation there should be a further subdirectory.
Thus we have outline/plasma/ with outline being the type and plasma
being the implementation. But at the moment the script location is still
hardcoded.

KWin already has a de facto OpenGL 2 dependency through QML. Combined
with the fact that the OpenGL 1 backend is basically unmaintained and
also unused, it's better to remove it for the new major release.
This change includes:
* Removal of cmake option KWIN_BUILD_OPENGL_1_COMPOSITING
* Removal of KWIN_HAVE_OPENGL_1 compile option and all code
ifdef'ed with it (partially removal of if-else constructs)
* Removal of CompositingType::OpenGL1Compositing (flags are kept
as a core flag should get introduced)
* Driver recommendation for OpenGL1Compositing changed to XRender
(should be evaluated whether the drivers can provide GL2)
* Removal of configuration option "GLLegacy"
* Removal of fooMatrix function in kwinglutils
* Removal of ARBBlurShader
* Removal of legacy code path in GLVertexBuffer
* Removal of GLShaderManager::disable
* if-blocks with ShaderManager::instance()->isValid() removed

The test application can verify that KWin correctly interprets the
WM_NORMAL_HINTS as described in ICCCM section 4.1.2.3 for the
combination of min size, base size and size increment.
Introduces an optional dependency to xcb-icccm library. It's optional
as the last time we tried to use it build.kde.org didn't like it at
all. Thus it should be possible to disable building this test app if
the dependency is not found.
As all effects have always been compiled into the same .so file it's
questionable whether resolving the effects through a library is useful
at all. By linking against the built-in effects we gain the following
advantages:
* don't have to load/unload the KLibrary
* don't have to resolve the create, supported and enabled functions
* no version check required
* no dependency resolving (effects don't use it)
* remove the KWIN_EFFECT macros from the effects
All the effects are now registered in an effects_builtins file which
maps the name to a factory method and supported or enabled by default
methods.
During loading the effects we first check whether there is a built-in
effect by the given name and make a shortcut to create it through that.
If that's not possible the normal plugin loading is used.
Completely unscientific testing [1] showed an improvement of almost 10
msec during loading all the effects I use.

This compositor uses only the QPainter API to perform rendering. The
window's X Pixmap is mapped to a QImage using XShm. As rendering backend
a QImage is used.
The new compositing type "QPainterCompositing" is introduced. Effects
need to be adjusted to explicitly check the compositing type and no
longer assume the compositing type is XRender if it's not OpenGL.
This compositor can be selected with using "Q" as the value for
KWIN_COMPOSE env variable or setting the config value to "QPainter".
The GUI is not yet adjusted to select this compositor.
The QPainter scene provides currently the following features:
* 2D transformations (translation and scalation)
* opacity modifications
* rendering of decorations (new PaintRedirector sub class)
* rendering of shadows
* rendering of effect frames
* rendering to a Wayland surface
The following features are currently not provided:
* saturation changes
* brightness changes
* 3D transformations
* rendering to X Overlay window
* offscreen rendering (e.g. needed for screen shot effect)
* custom rendering in the effects to the current back buffer
The functionality to create the connection to a Wayland compositor and
creating a fullscreen surface is moved into wayland_backend.(h|cpp). The
wl_egl_window for the surface is moved into the EglWaylandBackend to have
the actual WaylandBackend free from Egl. This will allow in future to
implement other compositing backends for Wayland which do not use egl.
This means that egl is no longer a build requirement for the wayland
related functionality.
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.
Instead we generate an export header for kdeinit_kwin and use it
to declare the KWIN_EXPORT. With this change our libs don't include
any KDE4Support headers any more. One step closer to no KDE4Support.
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
The xcb sync protocol is incorrectly defined (see [1]) which results in
xcb_sync_create_alarm not creating a valid alarm. To work around this
issue we only create the alarm without setting the int64 values. For
those we use the XLib XSyncChangeAlarm call after we verified that the
alarm got created. This unfortunately reintroduces linking against
libxext. But at least resizing works again.

The main purpose of the opengl testapp was to set the environment
variable LIBGL_ALWAYS_INDIRECT if direct rendering is not supported
before glx gets initialized.
With Qt5 we may no longer set this environment variable. QtQuick
requires direct rendering. On IvyBridge QtQuick is crashing if the
variable is set. Thus we are no longer allowed to set it and thus the
complete test becomes pointless.
The test app basically whitelisted most drivers anyway, the only
drivers which were problematic are the proprietary Catalyst drivers.
It that's still a problem we can also disable OpenGL compositing on
those drivers through the recommendation in the GLPlatform.
This also means that the KWIN_DIRECT_GL variable is no longer useful.
As KWin indirectly uses Qt's OpenGL through QtQuick we need to ensure
to not mix OpenGL and OpenGLES. So we have to built KWin only against
OpenGL if Qt is built against OpenGL and we have to built KWin only
against GLESv2 if Qt is built against GLESv2.
This means the kwin_gles binary is no more. There is only kwin which
either links GL or GLESv2.
Note to people compiling from source: it's only the default of the
cmake variable which got changed. You have to delete the variable
from the cache to get this change.
The DBusCall is exported as a QObject to the QML environment. It is
intended as a declarative replacement for the callDBus method which used
to be exported on global scope in the QtQuick 1 world.
Example usage:
DBusCall {
id: dbus
service: "org.kde.KWin"
path: "/KWin"
method: "setCurrentDesktop"
arguments: [1]
Component.onCompleted: dbus.call()
}
Getting all functionality from old solution into new one is not really
possible. Main problems are that QtScript provided more functionality
than the QJSEngine. For example it's no longer possible to just export
functions to the engine. We need to have a Qt wrapper object. At the
moment this wrapper object doesn't export all functions as the callbacks
are tricky. A solution might be to create specific QML types
encapsulating functionality which used to be exported on the functions.
Nevertheless a basic QML script loads and works and the ported readConfig
function works, too.
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.
1. it apparently is ineffective

ie. the overehad detection code gets a different opinion on __GL_YIELD than libGL

CCBUG: 322060
To ease porting a few features are disabled, this includes:
* kcms
* decorations
* activities
Note: KWin doesn't work yet, the event filter is not yet ported!
This dependency is causing build problems on a number of systems,
and it doesn't make much sense to bring in a whole library for three
one-line convenience functions.
Rudimentary support for input events. Events from Wayland are forwarded
to X's root window using the XTest extension.
Currently supported:
* left/middle/right mouse button
* keyboard events
Not supported:
* additional mouse buttons
* mouse wheel
* touch events
Obviously this is a rather huge hack and is only intended till we have
XWayland support and proper input redirection inside KWin.
This backend is able to composite on a Wayland surface instead of an X11
overlay window. It can be considered as a prototype for a Wayland session
compositor.
For texture from X11 pixmap the backend uses XShm. This is far from
optimal, but the KHR_image_pixmap extension is not available in Mesa's
Wayland backend. It's a temporary solution till we have XWayland and
texture from Wayland buffer.
To use this backend one needs to specify the environment variable
KWIN_OPENGL_INTERFACE with "egl_wayland". In future KWin should probably
use this backend if the Wayland display env variable is defined.
To use this setup:
1. Have a normal X-Server running on e.g. VT7
2. Start Weston on VT1
3. Start a terminal on Weston
4. start KWin with:
DISPLAY=:0 KWIN_OPENGL_INTERFACE=egl_wayland kwin --replace &
This should map a Wayland surface to Weston showing the content of the X
setup. At the moment it's not yet possible to interact with the surface
as input events are not yet recieved in the backend.
There are still a lot of limitations as documented in the code.
Main motivation for this change is that it's unhandy to have the class
definition in workspace.h and client.h while the implementation is in
events.cpp although nothing in events.cpp uses it directly.
By getting it out of workspace.h we get the header a little bit smaller
which should improve compile time given that it's included almost
everywhere.
In events.cpp the enum usage is changed to NETWinInfo as that's the class
where they are defined.
RootInfo does no longer hold a workspace pointer. Where it's needed it
uses the singleton accessor of Workspace.

* 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

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.
A new ClientModel is added which provides multiple different views on
KWin's Clients. The model is organized as a tree model supporting the
following levels:
* activities
* virtual desktops
* screens
* none
The levels can be ordered in whatever way one wants. That is the tree
structure can have an ordering of activities then virtual desktops or
the other way around.
In addition the model provides Exclusion flags to exclude clients of
certain types. E.g. it's possible to exclude all windows which are not on
the current desktop or all windows which are of type dock.
The model gets automatically updated whenever a Client is added/removed
or changes a state in a way that it should be excluded/included.
The ClientModel is not directly exported to QML. Instead there are
specific sub classes for certain common orderings. This solutions is
chosen to workaround some limitations of QML. The initial idea was to
use a property taking a list of the levels, but this doesn't work because
we are not notified when the QDeclarativeListProperty changes.
Currently the following models are provided to QML:
* ClientModel -> no restrictions
* ClientModelByScreen -> ordering by screen
* ClientModelByScreenAndDesktop -> screen, then desktop
These can be used to get all Clients:
ClientModel {
}
Or to get the classic Present Windows on current desktop:
ClientModelByScreen {
exclusions: ClientModel.OtherDesktopsExclusion | ClientModel.NotAcceptingFocusExclusion | ...
}
Or to get the classic Present Windows on all desktops:
ClientModelByScreen {
exclusions: ClientModel.NotAcceptingFocusExclusion | ...
}
Or our well known desktop grid:
ClientModelByScreenAndDesktop {
id: desktopGrid
exclusions: ClientModel.NotAcceptingFocusExclusion | ...
}
To support filtering as known by the Present Windows effect one can use
a ClientFilterModel, which is a QSortFilterProxyModel filtering on
window caption, role and class:
ClientFilterModel {
id: filterModel
clientModel: desktopGrid
filter: filterItem.text
}
In case it's a tree level obviously QML does not support this correctly.
So we need to use a VisualDataModel:
VisualDataModel {
id: clientModel
model: filterModel
Component.onCompleted: {
clientModel.rootIndex = modelIndex(0);
clientModel.rootIndex = modelIndex(0);
clientModel.delegate = thumbnailDelegate;
}
}
As we can see, the rootIndex has to be set to the level which contains
the Clients. Also it seems to be important to create the delegate after
the model index has been set. The idea is to have only one ClientModel
and multiple VisualDataModels if multiple views on the data is needed.
The model has been tested with a painful modeltest session. It looks good
so far modulo the listed limitations and that modeltest is not liking
closing Yakuake in the ClientModelByScreenAndDesktop setup, though it
works fine in real world testing.

Using a lib variable for:
* own libs
* qt libs
* kde libs
* xlib libs
* xcb libs
and link those groups together in target_link_libraries. This should
make the code easier to read and easier to support in future for some
time both Qt4 and Qt5.
A scripted component providing:
* ui/config.ui
* config/main.xml
can get a config interface by using the following in metadata.desktop:

X-KDE-PluginKeyword=`X-KDE-PluginInfo-Name`
X-KDE-Library=kcm_kwin4_genericscripted
X-KDE-ParentComponents=`X-KDE-PluginInfo-Name`
`X-KDE-PluginInfo-Name` has to be replaced by the actual value. In case
of a KWin Script the X-KDE-ServiceTypes needs to be:
X-KDE-ServiceTypes=KWin/Script,KCModule
The GenericScriptedConfig tries to identify the package from the keyword
and creates a Plasma::ConfigLoader and loads the UI from the packaged UI
file.
With Qt5 QCursor does no longer provide ::handle() which was used to
set a cursor on a native XWindow for which we do not have a QWidget.
Also KWin has had for quite some time an optimized version to get the
cursor position without doing XQueryPointer each time ::pos() is called.
These two features are merged into a new class Cursor providing more or
less the same API as QCursor.
In addition the new class provides a facility to perform mouse polling
replacing the implementations in Compositor and ScreenEdges.
For more information about the new class see the documentation for the
new class in cursor.h.
The code is rewritten in a way to replace the local event loop with event
filtering done in the normal way through events.cpp. Therefore instead of
creating a KillWindow whenever it's needed, there is one available in
Workspace which will be reused on next invocation.
The responsible events are passed from events.cpp to KillWindow for
processing.
In order to port the keycode to symbol to XCB, KWin now finds
xcb_keysyms and links it.
To get the right cursor KWin now links the XCursor library which is
unfortunatelly an XLib based library, but there seems to be no XCB
replacement.
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).

For the time being the current design of Options is more or less kept to
not have to adjust KWin code all over the place. Also for some parts the
generated class from KConfigXT cannot be used due to inter-settings
dependencies defined in the setters.
Options now holds a pointer to a Settings object which is generated from
KConfigXT and uses it to read the default values and the individual
settings. This means the static default value methods are dropped and the
variables are initialized with a normal default value (all int 0, all
boolean false and so on) in the initializer list. Afterwards the values
are set to the correct default value through KConfigXT.
So far for the first step only Windows category is using KConfigXT.

The extension handling is removed from kwinglobals and moved into the
xcbutils in KWin core in namespace KWin::Xcb. The motivation for this
change is that the Extensions are only used in KWin core and are marked
as internal. So there is no need to have them in the library.
What remains in Extensions are the non-native pixmaps. This will be
removed once we are on Qt 5 as QPixmap can no longer reference an XPixmap.
The remaining code in kwinglobals also still initialize the XLib versions
of extensions emitting events. It seems like there are no XEvents emitted
if not done so even if the extension is correctly initialized with xcb.
This needs to be removed once the event handling is ported over to xcb.

Most windows use the hostname in WM_CLIENT_MACHINE, but there are windows
using the FQDN (for example libreoffice). So instead of "foo" it is
"foo.local.net" or similar. The logic so far has been unable to properly
determine whether windows with FQDN are on the local system.
In order to solve this problem the handling is split out into an own
class which stores the information of hostname and whether it is a local
machine. This is to not query multiple times. To determine whether the
Client is on the local system getaddrinfo is used for the own hostname
and the FQDN provided in WM_CLIENT_MACHINE. If one of the queried
names matches, we know that it is on the local machine. The old logic to
compare the hostname is still used and getaddrinfo is only a fallback in
case hostname does not match.
The problem with getaddrinfo is, that it accesses the network and by that
could block. To circumvent this problem the calls are moved into threads
by using QtConcurrent::run.
Obviously this brings disadvantages. When trying to resolve whether a
Client is on the local machine and a FQDN is used, the information is
initially wrong. The new ClientMachine class emits a signal when the
information that the system is local becomes available, but for some
things this is just too late:
* window rules are already gathered
* Session Management has already taken place
In both cases this is an acceptable loss. For window rules it just needs
a proper matching of the machine in case of localhost (remote hosts are
not affected). And the case of session management is very academic as it
is unlikely that a restoring session contains remote windows.

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.
If the build option is enabled KWIN_HAVE_OPENGL_1 is passed as a compile
flag when build against OpenGL.
This compile flag is meant to replace the KWIN_HAVE_OPENGLES. So far code
has been ifdefed for special behavior of OpenGL ES 2.0 and to remove
fixed functionality calls which are not available in OpenGL ES 2.0.
With this build flag the fixed functionality calls which are only used in
the OpenGL1 Compositor can be removed and keeping the KWIN_HAVE_OPENGLES
for the real differences between OpenGL 2.x and OpenGL ES 2.0.
E.g. a call like glColor4f should be in an
glColor4f(1.0, 1.0, 1.0, 1.0);
while a call like glPolygonMode should be in an
glPolygonMode(GL_FRONT_AND_BACK, GL_LINE);
Building for OpenGL ES 2.0 of course implies that KWIN_HAVE_OPENGL_1 is
not defined.
The Egl backend is decoupled from the OpenGL ES build option which makes
it possible to use it as a replacement for glx.
To make this possible a new build flag is added when egl is available at
compile time and any egl specific code is now ifdefed with this flag
instead of the gles flag. In addition at runtime a windowing system enum
value is passed to the various detect methods to have egl/glx specific
detection for e.g. function pointer resolving.
By default egl is used if compiled with OpenGL ES, otherwise glx is used.
But in the non-gles case the windowing system can be selected through the
new environment variable KWIN_OPENGL_INTERFACE. Setting this variable to
"egl" the EglOnXBackend is used.

This build option is added to make it easier to build just KWin without
kde-workspace. This is a common requirement by developers wanting to
contribute to KWin and only want to build KWin but use everything else
from their normal distribution.
Building KWin standalone is very often difficult due to Oxygen. If the
library has changed it is not possible to build just KWin without also
building the workspace libs and if you do so you run into ABI problems
when trying to start KWin - either the decoration or the style is
crashing due to not matching libraries.
To circumvent this common issue for new developers this build option
is introduced to just exclude the Oxygen window decoration and defaulting
to Plastik.
Of course by default this option is turned ON, so that the Oxygen
decoration gets build. By default there is no change at all.

The backends take care of creating the OpenGL context on the
windowing system, e.g. on glx an OpenGL context on the overlay
window is created and in the egl case an EGL context is created.
This means that the SceneOpenGL itself does not have to care
about the specific underlying infrastructure.
Furthermore the backend provides the Textures for the specific
texture from pixmap operations. For that in each of the backend
files an additional subclass of the TexturePrivate is defined.
These subclasses hold the EglImage and GLXPixmap respectively.
The backend is able to create such a private texture and for
that the ctor of the Texture is changed to take the backend as
a parameter and the Scene provides a factory method for
creating Textures. To make this work inside Window the Textures
are now hold as pointers which seems a better choice anyway as
to the member functions pointers are passed.
Two new interfaces are introduced:
* org.kde.kwin.Compositing
* org.kde.kwin.Effects
The Compositing interface is generated from scriptable elements on the
KWin::Compositor class and the Compositor is exported as /Compositor.
It provides the general Compositing related D-Bus methods like whether
the compositor is active and toggling and so on.
The Effects interface is generated from scriptable elements on the
KWin::EffectsHandlerImpl class and the instance is exported as /Effects.
It provides all the effects related D-Bus methods like loading an effect
or the list of all effects.
This removes the need to have all these methods provided on the global
org.kde.KWin interface. For backwards compatibility they are kept, but
no longer provided by the Workspace class. Instead a new DBusInterface
is generated which wrapps the calls and delegates it to one of our three
related Singleton objects:
* Workspace
* Compositor
* EffectsHandlerImpl
As discussed on the mailinglist [1] the tiling support is
removed from KWin. The main reasons for this step are:
* it is unmaintained
* it is a mode not used by any of the core KWin team
* original developer said at Akademy 2012 that he is not
interested in picking up the work again
* tiling has quite some bugs, e.g. multi screen not supported
* is conflicting with other concepts in KWin, e.g. activities
There is ongoing work to get tiling supported through a KWin
script, which is a preferred way as it does not influence the
existing C++ code base.

BUG: 303090
FIXED-IN: 4.10
REVIEW: 105546
A CMake variable is used to specify the name of the binary.
By default this is "kwin" but building for PA changes the
name to "kwinactive". The variable adjusts all names, e.g.
kwinnvidiahack becomes kwinactivenvidiahack.
The remaining usage of kwinrc in core and libs is replaced
by a cmakedefine for the configuration name and all data
installations are moved to the defined name. Dynamic loading
for scripts & co is adjusted for loading based on defined name.
This change allows the side-by-side installation of both kwin
for desktop and kwin for Plasma Desktop without the known
issues like conflicts in config files or missing build options
if kwin desktop is used for Plasma Active.
Likewise the KCMs are not adjusted as they are not intended to
be used for kwinactive.

Further debugging functionality for KWin scripts. Added assert
methods validate the to be tested parameter and throw a script
error if the value is not valid.
Following methods are available:
* assert(value)
* assertTrue(boolean)
* assertFalse(boolean)
* assertEquals(expected, actual)
* assertNull(nullValue)
* assertNotNull(notNullValue)
All methods take an additional optional parameter which is used
as the error message if provided.
Methods to validate the number of arguments and types of the
parameters are added and throw syntax or type errors.

Scripted effects follow the Plamsoid package structure and the effect
loader recognizes a scripted effect at the according line in the desktop
file. If it is a scripted effect a different loader is used which
instantiates an object of the ScriptedEffect class. This class inherits
the AnimationEffect and exports the animate method and the EffectsHandler.
This script allows to have video fullscreen windows span all attached
screens creating a video wall.
This replaces the removed functionality that you could disable
xinerama support inside KWin for fullscreen windows.

Scripts are found by the KServiceTypeTrader and can now be
enabled/disabled. Loading of config is currently disabled. Will
be made available again after scripted effects are merged.
A new service type is introduced which is used by the KCM to find
all available window switcher layouts. This makes it finally possible
to have 3rd party window switchers.
Also the tabbox finds the packaged QML file through the service
definitions.
Desktop switcher is not yet in packaged version (UI to configure
is missing).

Unlike stated at several places in the code it is not difficult to
setup the connections to all Clients.
It would have been nice if the failed attempts to connect the Clients
would not have made it into the code as emitted signals which are
nowhere used. Not to mention that like in all places the signals to
inform that a state changed were emitted before the state changed was
performed.
This includes the delegates, the layout configuration for the delegates
and the custom view for the TabBox.
This can now finally be done as desktop tabbox is based on QML, too.
For this properties are defined in ClientGroup and several methods
are changed to be slots (to be invokable from scripts). On Client
the clientGroup is exported as a property.
The existing wrapper around ClientGroup is dropped as it is no
longer needed. Interestingly it was wrong anyway as it allowed to
construct a new ClientGroup, which has to be done internally.
At the same time the meta declarations get cleaned up a little bit.
Whatever it was, we cannot need a "Lazy Logic (TM)" which is not
documented. And even if it were useful, KWin is not the right place
to develop language extensions to ECMAScript.
Dropping the wrapper around Client and just exporting the Client's
properties. This breaks all existing scripts as it's now e.g.:
client.caption
instead of
client.caption()
But the first one is the more natural one for JavaScript and also
for everyone writing QML as well.
Setters and signals are mostly still missing in client. Other parts
like ClientGroup must be converted to properties, too.
A new QML item "ThumbnailItem" is registered to the TabBox. The
C++ implementation finds the EffectWindow of the TabBox and adds
itself to the EffectWindow.
While rendering the EffectWindow the information for all registered
ThumbnailItems are extracted and the thumbnail is rendered on top
of the EffectWindow.
This has obvious limitations like you cannot put other QML items
on top of the thumbnail. Nevertheless it works well enough to
be a possible replacement for e.g. BoxSwitch effect.
When compositing is disabled an icon is rendered instead of the
Thumbnail.
One TabBox Layout inspired by BoxSwitch Effect is added. For the
KCM small pre-rendered items are used.
REVIEW: 103039
All the default layouts (informative, compact, text, small and big icons)
are rewritten in QML and replace the ListView used before. The old code
is still around for the desktop switching modes which are not yet ported.
Next steps include to update the configuration module to not show now
obsoleted settings as well as providing a better way to choose the layout.

Due to changes in build system we have always either OpenGL or OpenGL ES.
This allows to remove the KWIN_HAVE_OPENGL_COMPOSITING define. In the
effects the define is kept as KWIN_HAVE_OPENGL which can be used in
future to build also an XRender only effect system.
Building the workspaces requires to have all the build dependencies
which were required for KWIN_HAVE_COMPOSITING to be set. This allows
us to remove all the ifdefs for this and gives us a cleaner code.
if both the GLES and EGL libs and headers are found.
Fold all the includes and libraries into 1 varaible each and use those.
in other words, you need to have both OpenGLES and EGL to do a successful build.
If we have OpenGL ES but not OpenGL the KWIN_HAVE_OPENGL is set
causing the first compile pass to fail as it tries to build
against OpenGL. As a solution the first pass links against
OpenGL ES if OpenGL is not found.
This means both kwin and kwin_gles are built against GLES.
A build option is introduced to file CMakeLists.txt. Classes Tiling,
Tile and TilingLayouts are only built if the option is set to ON. #ifdef's
are added to the classes where functions of the excluded classes are called.
KWin gets compiled twice if OpenGL ES is available
and a second binary is created. It is linked against
the GLES effects and kwinglesutils and does not link
against OpenGL. The normal OpenGL variant is still
the "kwin" binary.
This is an intermediate step till we have the scene
as a loadable plugin. Then we will determine whether
OpenGL ES is supported in an external application
and load it as a plugin, otherwise we load the
OpenGL/GLX scene as a plugin.

It is possible that adding this build option broke the Scripting
component. This is something that should not happen. Unfortunately
by just ifdefing everything scripting related with scripting enabled
we have build errors. These are caused by the fact that the scripting
code includes e.g. client.h through "./../client.h". At one offending
place I changed that to "client.h", but there is also a client.h in
the scripting directory.
The includes and naming of the scripting files clearly have to be fixed!
All the functionality of Overlay Window is moved to its own class
OverlayWindow. It is created and owned by class Scene, since almost
all function calls are called from this class.

This build option can be used to simplify the build settings for
the usage of KWin in Plasma Active. It includes:
* no decorations
* no kcms
* no tabbox
* only mobile effects
* turns on OpenGL ES (if available)
CCMAIL: sebas@kde.org
Since the TabBox functionality is not feasible for any platform KWin is
used on (e.g. tablet PCs), a build option is added to decide, if the
TabBox functionality should be build or not.

This initial commit introduces a two new files screenedge.h and screenedge.cpp which cover a new
class ScreenEdge. The code for screen edge handling was copied from Workspace to this class.
Workspace had to be extended by a getter for movingWindow. CMakeList was updated to build the
new class.
The new build option restricts the building of effects to those
useable for Plasma Active:
* blur
* dialogparent
* fade
* login
* outline
* presentwindows
* slidingpopups
* taskbarthumbnails
* screenshot
Additionally all effect KCMs are excluded from building in the
assumption that when building with this option, KWIN_BUILD_KCMS
is turned off.

For a complete documentation of new functionality refer to:
http://community.kde.org/KWin/Shadow
The current implementation includes a new Shadow class and Toplevel
holds a pointer to an instance of this class. The Shadow class reads
the data from the X11 Property. There is one extended class located
in SceneOpenGL to render the shadow.
Compositor is adjusted to include the shadow region into the painting
passes.
Implementation for XRender still missing and Shadow needs to respond
to size changes of the Toplevel to update cached shadow region and
WindowQuads.
Second part of cleaning up the lib directory: the effects library
now lives in libkwineffects/ directory.
For existing effects nothing changes as the install path is unchanged.
The change obsoletes the lib/ directory.
As glplatform.h has not yet been exported I dared to export it and
adjust the places where it is used.
CCMAIL: kwin@kde.org
The KDecoration library lives in libkdecorations/ now.
Installation pathes are unchanged, so this does not influence 3rd party
decorations.
The changes in the KWin main directory are required due to incorrect
includes.

Merging scripting from
^/branches/work/kwin_scripting TO
^/trunk
svn path=/trunk/KDE/kdebase/workspace/; revision=1177865
to a branch, but instead committed to the trunk. Well, the trunk was
broken because not all files were committed and hence anyone who checked
out of the trunk during this time could not have built kwin.
From what I can gather, the trunk has been broken for around 45 minutes
now. I didn't realize all that while that the trunk was broken. I
apologize for the inconvinience and I deeply regret my actions which
were clearly not well-thought.
Sorry,

main.cpp : Added a command argument. If 'stest' is set, then a testing
environment is setup which is used to test scripting for kwin.
Currently, the test setup only consists of loading a default script, but
in the feature it is expected to run a small text editor kind of thing
for testing.
Usage:
kwin --stest
CMakeLists.txt : Add the files corresponding to kwin_scripting the main
intention of which is to provide scripting support for kwin.
kwintabbox.desktop : An unintentional edit. Mostly harmless.
