python-qt-mvc

examples using python-qt's MVC framework for GUI applications

example-no-db.py

This example creates a conversation view from QAbstractListModel and a view function from QListView to show a toy list of messages / conversation view. By interacting directly with the model object, we can have it "automatically" update just the UI elements that need updating via signals/slots. This is done via the dataChanged signal (in setData) and using utility methods like QAbstractListModel.beginInsertRows (in addData).

$ python example-no-db.py
