getdir in c++, to choose a saving directory

Question

I have a qdialog with a qlineedit where the user can write his chosen path to save a file. I would like to implement a pushbutton (Open) where if the user presses it, it will be something similar to uigetdir in matlab. it returns the path chosen in a string. Any suggestions in c++?

Thank you.

Answer 1

QFileDialog offers the ability to select directories. Especially getExistingDirectory should cover your use case.

Answer 2

QFileDialog::getExistingDirectory
