Hmm what you say sounds good so far..
"Your TaskData and EmpData classes are delegates -- components that should be used to display (and otherwise interact with) data from a model" I agree to that and got that (i think)..
Means I have Delegates that don't have any data by heart and the delegates are provided X-times according to the Listmodel which holds the data for each Delegate - this might be set via setItemData() correct? And in the delegate I can access the data via the role.

What for do i need the QDeclarativeItem anyways? If the Delegate interacts with the model that thing is not needed? By now it is working without it..

If i store the data in the model directly i have to use different model instances - correct? At the moment i am using one instance for Tasks and Events thats why i
used virtual functions and the Abstractlayer

What would you do with
Qt Code: 
  1. private:
  2. EmpData m_data;
  3. };
To copy to clipboard, switch view to plain text mode 
in the case above ? how does the model interact with that Data?
