QComboboxdelegate

Hello. I have a Question to the QItemDelegate. I build a class ComboBoxDelegateByList with this class i can show several Comboboxdelegates in, for example a Tableview. That works fine. Now i have for example one column (Column 1) filled with ComboBoxDelegates… What i want to do is that all this Delegates in Column 1 change their content if i update the content. All ComboboxDelegates have the same content. But now i dont know where to start… I have the … ComboBoxDelegateByList::setModelData(QWidget* pEditor, QAbstractItemModel* pModel, const QModelIndex& index) const … Method, but here i can not edit all the columns only one. I thing the best approach is to update the comboboxdelegate in the model or not? Or can i set the data via the setData Method of my Model. Someone knows a other good approach? Thanks.
