Do you surround your array manipulation with beginInsertRows() and endInsertRows()?

The Table > stays empty. the dataChanged signal only tells the model that the content of the given cell changed, not that the structure of the cells changed. You need to do use the begin/end functions to do that. - Best regards, Gunnar _______________________________________________ Qt-jambi-interest mailing list [email protected] http://lists.trolltech.com/mailman/listinfo/qt-jambi-interest
