Hi Andreas! Yes, the model isn't properly implemented, still not sure why I'm getting a segfault rather than infinite loop. Might be some internal stack overflow?
Anyway, thanks for your reply! I didn't even consider it would would try using children indices since a table model doesn't/shouldn't have them. Thanks a bunch! /Peter On 2010-08-09 (Mon) 12:20, Andreas Pakulat wrote: > On 09.08.10 12:06:57, Hans-Peter Jansen wrote: > > Hi Peter, > > > > while not of big help, here are a few more details and the backtrace. > > > > Qt 4.6.3, sip 4.10.5, PyQt4 4.7.4. > > > > On Monday 09 August 2010, 09:42:05 [email protected] wrote: > > > Yes, the connect signal had the wrong signature, but that doesn't matter. > > > I do not get a warning when trying to connect invalid signals, but > > > even if I have no activated-signal connected, the darn thing still > > > segfaults when I double click any cell. > > > > Well, even with a correct signal, this crashes (after executing the signal > > handler): > > > > import sys > > from PyQt4 import QtGui, QtCore > > > > class TestModel(QtCore.QAbstractTableModel): > > > > def headerData(self, section, orientation, role = > > QtCore.Qt.DisplayRole): > > return QtCore.QVariant("a") > > > > def data(self, index, role = QtCore.Qt.DisplayRole): > > if (role == QtCore.Qt.DisplayRole > > and index.isValid() > > and 0 <= index.row() < 2 > > and 0 <= index.column() < 2): > > return QtCore.QVariant("t") > > return QtCore.QVariant() > > > > def columnCount(self, index): > > return 2 > > > > def rowCount(self, index): > > return 2 > > If you use this model on a treeview you'll probably end up in an infinite > tree size.
