      Please post code not screenshots.

      So have you done what https://doc.qt.io/qt-6/qabstractlistmodel.html#subclassing tells you that you must do?

            @ceydasimsekk Whether you are new or not you likely have not done what that link tells you that you need to do.

              Hi,

              Did you implement all the required pure virtual methods from the base class ?
              Without doing that, you class is also an abstract class.
