How to use QStringList to store multiple strings - c++

Question

I'm using QT framework to create an employee interface which stores information of an employee (ID, name, surname, skills, ecc..)
In the widget interface I've used a lineEdit for everything since I need to store string types of information, the only exception of parameter skills that should be a list of strings
In my mainwindow.cpp however I should store a list of different skills, not just one, and that's get me the error when I use my function .addEmployee() because it wants a list of skills, not one string.
I should use QStringList skills but how can I tell the user is inserting different skills and store them as a list?
void MainWindow::on_add_pushButton_clicked()
{
QString id = ui->id_lineEdit->text();
QString nome = ui->name_lineEdit->text();
QString cognome = ui->surname_lineEdit->text();
QString skills = ui->skills_lineEdit->text();
// should be QStringList skills but how can I tell the user is inserting different skills?
manage.addEmployee(id.toStdString(), name.toStdString(), surname.toStdString(), skills.toStdString());
// manage refers to the class manageEmployee.h I already implemented to use function addEmployee(id, name, surname, {skills});
}

The question is a bit unrefined, but I will try my best to answer based on what I could follow.
void MainWindow::on_add_pushButton_clicked()
{
QString id = ui->id_lineEdit->text();
QString name = ui->name_lineEdit->text();
QString surname = ui->surname_lineEdit->text();
QString skills = ui->skills_lineEdit->text();
QStringList skillsList = skills.split(","); // or ";", etc.
std::list<std::string> skillsStdList;
for (const QString& qstr : skillsList) {
skillsStdList.push_back(qstr.toStdString());
}
manage.addEmployee(id.toStdString(), name.toStdString(), surname.toStdString(), skillsStdList);
}
So if you want the user to input list of skills, you wanna be splitting them using a delimiter as well.
Then you can pass the resulting QStringList to .addEmployee assuming it takes a fourth argument std::list<std::string>
By using a delimiter, you allow the user to enter multiple skills as a single input, which simplifies the interface. However, you should make sure to handle any errors that can arise from invalid input, such as an empty or malformed input string.
Edit: Code updated in mind with QList<Qstring> not supporting toStdString method
