QComboBox signal and slot connection problems

[Yosei]

I am developing an application for testing students and I have a problem connecting a signal from a QComboBox to my slot. I tried to use the new connect-function syntax but nothing works:

connect(gradeBox, &QComboBox::activated(QString), this, &HomeWindow::printGrade(QString));

this causes a lot of errors, homewindow.cpp line 60 is line with "connect":

I tried to use various options for recording a parameter in a signal and slot as "const QString" , "QString&" or "const QString&" but this isn't working anyway. I readed Qt Documentation but don't find answer. What am I doing wrong?

Hi
Its due to it being overloaded so there is an INT version and STRING version

try
connect(comboBox, QOverload<QString>::of(&QComboBox::activated), this, &HomeWindow::printGrade);
