Passing objects derived from 'B' to functions that expect parameters of type 'B'

[Exotic_Devel]

I think this is a matter of OOP.

In my test I am getting a type error:

@expected data of type 'QObject*', got 'TestDataAccess*' for element 0 of data with tag 'Normal'@

But 'TestDataAccess' is derived from QObject. How to make the method receives any object that derives QObject?

did you tried to cast it?
like @
AtpSingleApplication *singleApp = qobject_cast<AtpSingleApplication *> (qApp);@
