QFileDialog select multiple directories

Using a QFileDialog, I can allow the user to select one or more files, or to select one directory. Is there any way to allow selecting multiple directories?

I have found this FAQ on the qt-site, but the code there doesn't work (even after fixing the typos).

Any ideas?

thanks,

It seems that the QFileDialog won't do it out of the box. My solution would be to build a new directory picker dialog for your application, supporting multiple directories. By using a QFileSystemModel, you don't have to worry about traversing the file system.

My guess would be that the solution posted in the FAQ can't work with the OS-native filedialogs, which are used by default.
The native dialog won't have a QListWidget etc..

Try opening a qt one.

Code:

---

filedialog.setOption(QFileDialog::DontUseNativeDialog,true);

I just checked; multiselection works:

Code:

---

#include <QtGui>
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QFileDialog w;
    w.setFileMode(QFileDialog::DirectoryOnly);
    w.setOption(QFileDialog::DontUseNativeDialog,true);
    QListView *l = w.findChild<QListView*>("listView");
    if (l) {
         l->setSelectionMode(QAbstractItemView::MultiSelection);
     }
    QTreeView *t = w.findChild<QTreeView*>();
     if (t) {
       t->setSelectionMode(QAbstractItemView::MultiSelection);
   }
   return w.exec();
}

It works no matter what I set the DontUseNativeDialog to. I can't seem to get the native dialog going! Strange!

I'm on Win7. Qt4.7. Mingw.

The following codes are a good solution to select multiple directories and files in the same QFileDialog. Thanks!
