    Can I do something like this?

    ui.type_search_cbo->cancelEventoncurrentIndexChanged;
    ui.type_search_cbo->setModel(model);
    ui.type_search_cbo->resetEventoncurrentIndexChanged;
    

    (nice code, eh?)

      well i would prefer if you could just wait to connect the slots
      so its ok it says index changed.

      There is
      http://doc.qt.io/qt-5/qobject.html#blockSignals

      but again, you are fixing a symptom so it not the best.

        Yes, it works with block signals.
        So, this is not the correct remedy?

        How could I wait to connect the slots?
        I don't want just to fix the symptom, I want to do it properly.

          well where do you hook up the oncurrentIndexChanged signal?

            It's a slot for a combo:

            void RepairDevices::on_type_search_cbo_currentIndexChanged(int index)
            {
                refresh_devices_search_tbl(); 
            }

              @Panoss said in How to access QSqlRelationalModel from function?:

              Ah you are using the auto connect feature?
              you do not have connect( xxxx) , correct ?

                No, I don't even know what autoconnect is.
                I have no connect( xxxx) for this function.
                (unless you 're meaning that this way, it 's autoconnected)

                  well it means it will hook it up if names matches.
                  QMetaObject::connectSlotsByName(MainWindow);
                  ( in setupUI)

                  just use blockSignals then. :)
