Ok, thanks now I do understand your problem. Unfortunately I can't reproduce it here with your example application. After editing two cells and clicking Cancel the view is updated to reflect the original data and I get TestModel.setResultset called fillTable called TestModel.setResultset called Signal modelReset empfangen In the console, so its clearly working. What version of Qt4 are you using? (I'm on 4.2.x here, where x is IIRC something around 2) If you can't change your Qt version, try emitting the dataChanged Signal with the top-left and bottom-right QModelIndex. > BTW: Did you look at the > > ready-made models for accessing SQL databases in Qt4? > > I didn't understand how to get the SQL support for Firebird.

Well, if firebird libs and includes are in different directories use the -I and -L flags to Qt4's configure (or use the system-provided Qt4 if it includes firebird support - which it should). For example I run configure -I/usr/include/mysql -I/usr/include/postgresql to get the mysql and postgresql driver built (am using plain Debian here) Andreas -- Is this really happening? _______________________________________________ PyKDE mailing list [email protected] http://mats.imk.fraunhofer.de/mailman/listinfo/pykde
