Thanks for the detailed answer. 

As I am writing my GUI code by hand and not using anything like Qt Designer or 
Qt Quick I sometimes find it hard to identify the borders/interfaces between the 
view and the controller. I will also have a look at QtTest. 

I think [1] would be a good literature to learn something about design patterns 
with Qt. Can anybody recommend this book maybe? 


Best regards, 
Markus
