This is going to be a controversal change. It enforces KWin decorations
on all client side decorated windows from GTK+. Unfortunately we are
caught between a rock and a hard place. Keeping the status quo means
having broken windows and a more or less broken window manager due to
GTK+ including the shadow in the windows. This is no solution.
Enforcing server side decorations visually breaks the windows. This is
also no solution. So why do it?
It's our task to provide the best possible user experience and KWin is
a window manager which has always done great efforts to fix misbehaving
windows. One can think of the focus stealing prevention, the window rules
and lately the scripts. The best possible window management experience is
our aim. This means we cannot leave the users with the broken windows
from GTK.
The issues we noticed were reported to GTK+ about 2 months ago and we are
working on improving the situation. Unfortunately several issues are not
yet addressed and others will only be addressed in the next GTK+ release.
We are working on improving the NETWM spec (see [1]) to ensure that the
client side decorated windows are not in a broken state. This means the
enforcment is a temporary solution and will be re-evaluated with the next
GTK release. I would prefer to not have to do such a change, if some of
the bugs were fixed or GTK+ would not use client-side-decos on wms not
yet supporting those all of this would be a no issue.
For a complete list of the problems caused by GTK's decos see bug [2] and
the linked bug reports from there.
The change is done in a least inversive way in KWin. We just check for
the property _GTK_FRAME_EXTENTS and create a Q_PROPERTY in Client for it.
If we add support for the frame extents in future we would also need
this. So it's not a change just for enforcing the decoration.
The actual enforcing is done through a KWin script so users can still
disable it.

Adds NET::WM2BlockCompositing to the Client's properties which allows to
read the state from the NETWinInfo object and get updates without having
to resolve the atom ourselve.
REVIEW: 117561
It's provided by the NETWinInfo, no need to keep an own implementation.
To keep compatibility with existing KWin code using the window class or
resource it's always converted to lower.
In addition a notify signal Toplevel::windowClassChanged is added and
emitted from the event handler whenever the WM2WindowClass property is
set.
REVIEW: 117496
NETWinInfo provides windowRole if NET::WM2WindowRole is added to the
properties2. Thus KWin doesn't need to monitor and fetch itself, but
can just wrap the data provided by NETWinInfo.
In addition a signal is added to Toplevel whenever the window role
changes.

This provides a new protocol intended to be used by auto-hiding panels
to make use of the centralized screen edges. To use it a Client can
set an X11 property of type _KDE_NET_WM_SCREEN_EDGE_SHOW to KWin.
As value it takes:
* 0: top edge
* 1: right edge
* 2: bottom edge
* 3: left edge
KWin will hide the Client (hide because unmap or minimize would break
it) and create an Edge. If that Edge gets triggered the Client is shown
again and the property gets deleted. If the Client doesn't border the
specified screen edge the Client gets shown immediately so that we
never end in a situation that we cannot unhide the auto-hidden panel
again. The exact process is described in the documentation of
ScreenEdges. The Client can request to be shown again by deleting the
property.
If KWin gets restarted the state is read from the property and it is
tried to create the edge as described.
As this is a KWin specific extension we need to discuss what it means
for Clients using this feature with other WMs: it does nothing. As
the Client gets hidden by KWin and not by the Client, it just doesn't
get hidden if the WM doesn't provide the feature. In case of an
auto-hiding panel this seems like a good solution given that we don't
want to hide it if we cannot unhide it. Of course there's the option
for the Client to provide that feature itself and if that's wanted we
would need to announce the feature in the _NET_SUPPORTED atom. At the
moment that doesn't sound like being needed as Plasma doesn't want to
provide an own implementation.
The implementation comes with a small test application showing how
the feature is intended to be used.

By setting the X property _KDE_NET_WM_SKIP_CLOSE_ANIMATION to 1 a window
can request to be excluded from any close animation. This property is
read in Toplevel, so that it is available to both Client and Unmanaged.
If the window has this property set the Scene suppresses the paintWindow
loop of the Deleted. Thus no effect needs to be adjusted. But an effect
using drawWindow directly would still be able to render the Deleted as
there is no suppression.
Furthermore the property is passed to the EffectWindow so that an
Effect can make use of this functionality and not start the animation
in the first place.

The X property _KDE_NET_WM_COLOR_SCHEME can be set on a window and
specifies the absolute path to a .color file describing the color
scheme of the managed client.
The Client reads this property and creates a QPalette from it. If
the property is not set or the value is incorrect, the Client uses
KWin's default palette.
The idea behind this property is to allow an application with a
custom color scheme to tell KWin which color scheme the window
decoration should use. So that the window looks as a solid pattern
again.
F(S)UM mean "the focus is where the mouse is"
the mouse is not on the other virtual desktop
(and it was even granted regardless of the actual geometry/position)
The "unreasonable" focus policies expose an issue about
the present linked handling of "allow activation" and
"allow raising" (see https://git.reviewboard.kde.org/r/110919/ )
Activation would match "extreme" (if the window maps on the same
virtual desktop, half a mile away from the mouse, it won't
receive the focus) but not regarding raising (which is actually
an issue entirely different from FSP)

The frameId only makes sense for a Client, in case of Unmanaged the
same window id is used as for the window() handle. Client creates the
frame and destroys it.
Given that it makes sense to let Client manage the frame properly.
The ::frameId() is therefore virtual and as base implementation it
returns the client id. Client reimplements it and returns the proper
frame id.
Method is also implemented in Deleted as it used to be passed to
deleted.

Unfortunately the Xcb::Window wrapper cannot be used for the client
window as the client should not be destroyed by KWin.
All the API calls except XSelectInput are changed to xcb and the name is
adjusted to m_client to follow the naming scheme.
The Xcb::Window nicely encapsulates the created wrapper window. As
almost all code is adjusted, the variable is also renamed to
m_wrapper to follow the normal naming scheme.
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.

Overall all notifications except compositing suspended by DBus were
configured by default to not have any action. This means all the time we
emit a notification we keep DBus and KDED busy for nothing.
All the cases when a notification is triggered ire also exported to
KWin scripting, so if one really needs to handle something in case a
window is moved, it could be done through a KWin script with much more
context about the event.

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.
and btw. replace legacy "ignoreposition" by "ignoregeometry"
this will allow to use "apply initially" as "force" used to act
(ignore position on placement) and "force" to prevent clients
from reconfiguring themselves (to not break a tabgroup or to just
not be annoying)

The hack used to be used to hide windows before they get embedded into
another window. This has been wrong on multiple levels:
1. it does not belong into a window manager - the window should take care
of this by itself
2. Window title is not a proper way to identify windows
3. Using D-Bus to inform an X11 window manager about windows which should
not get managed is rather strange
4. The hack only works with KWin, but not with any other X Window Manager
5. Windows identified with this hack still appear in Alt+Tab, that is
they are managed after all. Only a flicker is suppressed
6. Such windows are shown in the taskbar which nicely illustrates how
wrong a D-Bus call to the window manager is
That the hack has been introduced for Java Applets in KHTML also shows
that this is wrong. Why does Gecko and WebKit not need such a hack? Why
is KHTML tied so closely to X11 and KWin? Having a hack for a technology
which is obsoleted (Java Applets) and shouldn't be used due to security
issues is another reason to no longer support this hack. This usage has
been removed from KHTML as of 67939b1 of kdelibs git repo.

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.
instead of just checking whether the decorated client will be bigger
than the workarea and take that as reason to maximize it, we will not do
so if it's smaller than the full are and the managed client bigger than
the screen (because it makes sense for the user to move it around and the
requested dimension is out of what the client could have stored when closing
maximized)
REVIEW: 108705
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.

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.
The two methods:
* place
* placeSmart
have only forwarded the call to the Placement object. Now that Placement
is a singleton there is no need to have them. Every user can call them
directly without going over Workspace.
as the flamewar pointed out, resetShowingDesktop invalidly keeps hidden windows
the reason is that there're several updateVisiblity calls (notably one from the compositor)
which break the showingDesktop state as a side effect (before ::manage() does it's thing)
Since they also invalidate the Withdrawn mapping state, that will fail as isManaged() test
(it's also invalidly used by the compositor to set up the decoration, isManaged() used to be
true because of the updateVisibility() call before) since the result is never Withdrawn

Behavior is now like all xinerama related options are enabled.
There seems to be no valid reasons to run multi screen without
xinerama support and even if a user would wish to do so she can
just disable xinerama in xorg.conf.
Furhtermore thanks to KWin scripting it is possible to achieve the
behavior as it used to be with the options disabled. E.g. it is
possible to span a window in fullscreen mode over all screens.
This change is in accordance to the discussion on kwin and plasma
mailinglists:
http://mail.kde.org/pipermail/plasma-devel/2012-January/018542.html
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.
I did something wrong. The recent four fixes for klipper bugs were
cherry-picked from master into KDE/4.8. So they appear twice in the
merged history.

Maximization of oversized windows must happen BEFORE keepInArea() is called
because that will through resizeWithChecks() lead to an artificial constrainment
to the WorkArea which is the combination of all screens minus all struts
this fails if only one screen struts and as a result the window is no more
bigger than FullArea which is used as maximization enforcing condition.
(Maximization must also happen AFTER placement, because otherwise the window
will eventually be maximized to the wrong MaximizeArea - Screens(s) - (local) struts
depending on xinerama settings)

This input-only window is used to capture events above the
client window and preventing them from reaching the client.
It is currently used to enlarge the borders by an invisible
amount, using the ExtendedBorderRegion provided by the
decoration.
This patch implements an XProperty named _KDE_NET_WM_OPAQUE_REGION
which gives the compositor the information which part of a window
is opaque although it is an ARGB visual. The basic ideas are from
http://www.mail-archive.com/wm-spec-list@gnome.org/msg00715.html
Additionally the patch makes kwin use this information to do a better
clipping in Scene::paintSimpleScreen which should result in a higher
performance.

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!
Since the funtionality of TopMenu did no longer work in KDE4 this feature was
removed from Workspace. Every reference to it was removed as well as commentaries
and documentation.
