No.

The mistake was trying to set a property from another thread. Do *not* touch a 
QObject from any thread other than the one it is is associated with.

If you add member functions to your QObject-derived class, you're welcome to 
call them. Just make sure that they do not call any other functions inherited 
from QObject.
