First of all: we cannot depend on anything in playground. This review has a push embargo till the library has gone through review.

Overall I dislike the extensive usage of ifdefs. I would prefer if the accessibility feature becomes a mandatory requirement for this effect to build. That is if LibKdeAccessibilityClient is not found the effect does not get build. I think this would make the code much cleaner to read and also to maintain.


kwin/effects/CMakeLists.txt

    this should be moved up to the main CMakeLists.txt of kde-workspace.



kwin/effects/zoom/focustrackconfig.h.in
<http://git.reviewboard.kde.org/r/106041/#comment13664>

    this file should then also be dropped and the cmakedefine be added to the config-workspace.h.cmake



kwin/effects/zoom/zoom.h
<http://git.reviewboard.kde.org/r/106041/#comment13665>

    if I see correctly you don't need the include in the header. Please use forward declaration if possible



kwin/effects/zoom/zoom.h
<http://git.reviewboard.kde.org/r/106041/#comment13669>

    the pointer does not get initialised in the ctor. Please default init with NULL



kwin/effects/zoom/zoom.cpp
<http://git.reviewboard.kde.org/r/106041/#comment13666>

    where does this pointer get deleted? It seems to be no QObject (no parent passed) and no delete in the dtor.



kwin/effects/zoom/zoom.cpp
<http://git.reviewboard.kde.org/r/106041/#comment13668>

    coding style: either Qt or KDE-libs coding style (I personally prefer KDE-libs):
    
    if (!success) {
        kWarning(1212) << "Could not connect signal to slot";
    }



kwin/effects/zoom/zoom.cpp
<http://git.reviewboard.kde.org/r/106041/#comment13667>

    please set a deleted pointer to NULL:
    registry = NULL;



kwin/effects/zoom/zoom.cpp
<http://git.reviewboard.kde.org/r/106041/#comment13662>

    we don't use this define inside KWin and we use kDebug(1212) instead of qDebug(). This holds of course for all usage of qDebug()
