deriving abstract classes from qt concrete classes

[user4592357]

i need to define interfaces for the application. these interfaces must work with widgets such as tree view, table view, etc. i wanna know how logical it is to derive classes from qt concrete classes (e.g. QTreeView) and make that class abstract?

Hi,

What exact interface do you want to add ?
Can you explain the context for creating such an abstract class ?

Hi
I think you have to explain in more detail the requirements as
QTreeView already derive from the abstract class
QAbstractItemView
https://doc.qt.io/qt-5/qabstractitemview.html
So it would seem odd to abstract the concrete class implementation. (imo) :)

update: too slow ;)

i need, for example, a populate() method which will populate the top level of the tree.

Then the question is: is it a class that you will provide through a library ?

In any case, nothing stops you from creating an abstract subclass with that method as pure virtual.

@sgaist
yeah it is going to be some kind of library, and that's why i need to make the abstractions...

Then, as the logo says: Just do it :-)
