Hi and welcome to devnet,

You have no GetClientNames function in your class declaration. You must first add it there.

Note that it's not something Qt specific but C++ in general.

You need to declare the method in the header, not only provide definition in the source file:

class MainWindow : public QMainWindow
{
    Q_OBJECT
    // ...

    QString GetClientNames(int); //< You need this
};
