QFormlayout with three options on the same line

[Nafab213]

For my program I inserted a Qformlayout but I would like the three options () to be on the same line. Like this
Votre Classe : listedesclasses Série: listedesclasses, N°: listedesclasses
How can I do ?
Here's the code

 QFormLayout *cridebase = new QFormLayout;
    cridebase->addRow("Votre Matière", listedesmatiere);
    cridebase->addRow("Son Coeficient", coeficient);
    cridebase->addRow("Classe", listedesclasses); //1
    cridebase->addRow("Série", listedesseries); // 2
    cridebase->addRow("N° Classe", numerodeclasse); // 3    (1 + 2 + 3 on same line)

    QGridLayout *critdbase = new QGridLayout; //Un grille layout pour disposer correctement les différent élements de la fenêtre
    critdbase->addWidget(bienvenue, 1, 0, 6, 6);  //(bouton3, 1, 0, 1, 2);
    critdbase->addLayout(cridebase, 7, 0, 6, 6);
    critdbase->addWidget(bttcreer, 8, 3);
    critdbase->addWidget(bttannuler, 8, 5);

I left the QGridlayout because I looked for the solution with him but it did not work.
I am beginner so be explicit.
Thank you in advance...

Im not 100% sure, but I think you can use only 2 widgets (i.e. one for a label and one for a LineEdit) per line in a formlayout?!

You can use a GridLayout in this case or you combine multiple Horizontal- and Vertical-Layouts

@Nafab213 Put these 3 widgets as children on a parent widget and put this parent widget to the form layout.
