You probably want to subclass QAbstractTableModel. This doesn't fix the problem but will prevent other problems/warnings. > def rowCount(self, index): > return 1 > > def columnCount(self, index): > return 1 > > def data(self, index, role) : > i, j = index.row(), index.column() > if role == Qt.DisplayRole : > return '\n'.join(["data %d"%i for i in range(1000)]) > > def index(self, row, col, parent=QModelIndex()) : > return self.createIndex(row, col, 0) You shouldn't need to reimplement index() for a table model.

It looks like there's a bug in Qt that only occurs if there is only one row in the table. If you change the return value of rowCount() to 2 then you get the desired behaviour. Perhaps it would be worth looking in the bug tracker at bugreports.qt-project.org for a similar bug report, or file a new one.
