Model/View data access

HojjatJafary

The data access interfaces in the QAbstractItemModel class force the subclasses to use QVariant when getting/setting data to the model.

There are two ways to access the internal data of my model:

Use Q_DECLARE_METATYPE macro for all of my internal data classes so they can be used with QVariant.

OR

Which one is reasonable with the expected use of Qt Model/View.

Add my custom data access methods. (custom get/set functions).

This also requires the delegate to get tied up with the model.

I'm a fan of solution 1 but, in the interest of pragmatism, I'd say use the path that is less painful to implement for you.

P.S.
Classes that include the Q_GADGET macro are already registered metatypes so you can go down that route as well
