reimplement the type() function for each custom QGraphicsItem subclass.
Do that in the example code.

Qt provides extensive database interoperability, with support for products
from both open source and proprietary vendors.

SQL support is integrated with Qt's model/view architecture, making it easier
to provide GUI integration for your database applications.
