Marcel,

Look the difference here :

http://websvn.kde.org/trunk/extragear/libs/kipi-plugins/gpssync/gpslistviewitem.cpp?r1=text&tr1=594449&r2=text&tr2=594746&makepatch=1&diff_format=h

Before my commit, the QObject instance used to create the GPSListViewItem object is null ! this is want mean that, in special cases (when Qt is compiled with special options i think), the main Qt event will be not available to the object. I have just connected the child QObject instance to the parent QObject instance, witch is a KListView in GPSSync plugin.

About digiKam core implementation, i think that we need to pass a parent QObject instance in object constructors to receive all events dispatched by the main Qt loop.

I have already talk about this point in the past with Renchi when i have implemented the CDArchiving kipi-plugins. With this tool, we have seen a problem to recieve the KProcess events to drive K3b.
