How to access QSqlRelationalModel from function?

Panoss

I found the guilty!!With the debugger.
It's a combo box which calls the function at oncurrentIndexChanged event!
This means that when a combo gets data from a model, the oncurrentIndexChanged event is called!!
How can I fix this?

@Panoss
I think its by design.
When it get data, the current
index is changed so its correct to
emit the signal.
Check current index before and after and see.

Most likely its 100% correct and you might need to use other signal or
wait until after the data load to set the connect.

ps. Good work with debugger :)

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?)

@Panoss

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.

Panoss

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.

mrjj

@Panoss
well where do you hook up the oncurrentIndexChanged signal?

Panoss

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 ?

Panoss

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)

mrjj

@Panoss

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

just use blockSignals then. :)

Panoss

Thank you very much mrjj, you helped me A LOT!
