Maybe you can add a directory filter to achieve this.

c gtk

    I took some tags unnecessary for the problem. Are you even using C? Or C++? Or is one or the other. I don’t know if I get it. One of the functions of this dialog is to let the user select a folder. I will try to respond with what I understood.

You probably would have to use the method set_action with the right filter option. Something like this:

seuDialogo.set_action(gtk.FILE_CHOOSER_ACTION_SELECT_FOLDER)

Has an example here in C++.

Gtk::FileChooserDialog dialog("Please choose a folder", Gtk::FILE_CHOOSER_ACTION_SELECT_FOLDER);
