Solved cannot use QVector as a parameter to signal

[GunkutA]

Hello, I am trying to send a QVector that consists of QStrings, by using signal-slot mechanism.
I created the Signal as follows in header file:

void sendInitDataToMath(QVector <QString> selectedNames);

And this is the receiver slot declaration:

void receiveInitData(QVector <QString> selectedNames);

When I try to connect these signal and slot as

void protocolForm::on_button_openMath_clicked()
{
    mathFormInstance = new mathForm();
    mathFormInstance->show();
   connect(this,&protocolForm::sendInitDataToMath,mathFormInstance,&mathForm::receiveInitData);

}

I receive "undefined reference to 'protocolForm::sendInitDataToMath(QVector<QString>)' " error. Is this because we cannot use vector parameters as parameters to signal-slot? How can I solve that?

nope, it's because you forgot to #include<QVector>

@J-Hilk But still the same error after I added #include <QVector>

@GunkutA depends on where you added that, sender and receiver class should know how to use QVector

@J-Hilk Yes... that solved that. Thanks a lot.
