cannot call member function without object

[been_1990]

I made it static because that's the only way it would work with QAbstractEventDispatcher(). I was experiencing some difficulties with setting QAbstractEventDispatcher() filter and a thread here in QtCentre Forum said that I should make eventFilter() static, I did and it worked. Only for that reason. But if there is a better way I would really like to know.

EDIT:
if I remove "static" from eventFilter I get this error message:

qapp.cpp: In constructor 'QApp::QApp(int&, char**)':
 
qapp.cpp:14: error: no matching function for call to 'QAbstractEventDispatcher::setEventFilter(<unresolved overloaded function type>)'
