- Data for all available roles can be obtained at the same time using the PySide.QtCore.QAbstractItemModel.itemData() function.
- When subclassing QAbstractItemModel, at the very least you must implement index(), parent(), rowCount(), columnCount(), and data().

- Let’s see that in this QAbstractItemModel tutorial. ... The QAbstractItemModel isn’t the simplest model to understand but with it you’ll be able to use all the views.
