QAbstractEventDispatcher - does anybody have experience with subclassing it?

[thEClaw]

I am currently having some trouble "integrating SDL into an application":http://qt-project.org/forums/viewthread/39368/ . After what I have read, subclassing "QAbstractEventDispatcher":http://qt-project.org/doc/qt-5/qabstracteventdispatcher.html would be the most elegant and powerful solution to my problems. But the class contains 14 pure virtual methods and there don't seem to be any examples available (even the documentation is not on par with most of the more frequently used classes).

I sadly have no idea what kind of trouble I would conjure with subclassing and using my own event dispatcher. I also don't know how to reimplement all of the virtual methods (my application should still run on all major platforms). Has anybody ever done this and could explain some details or even give a minimal viable example?
