One thing that was strange in your example was that you were subclassing
QAbstractListModel, but calling the __init__() method of the
QAbstractTableModel.

Anyway, here's a simple, complete example that should work:


import sys
from PyQt4.QtCore import QObject, SIGNAL
from PyQt4.QtGui import *

def slot(selected, deselected):

    print len(selected), "items selected"
    print len(deselected), "items deselected"


if __name__ == "__main__":

    app = QApplication(sys.argv)
    model = QStandardItemModel()
    for i in range(10):
        model.appendRow([QStandardItem("Item %i" % i)])
    
    listView = QListView()
    listView.setModel(model)
    listView.show()
    
    QObject.connect(listView.selectionModel(),
        SIGNAL("selectionChanged(QItemSelection, QItemSelection)"),
        slot)
    
    sys.exit(app.exec_())


Does that help in any way?
