QFileDialog: Selecting directories and files

问题

I'm using the code below to build a qstringlist of filenames:

QStringList filenames = QFileDialog::getOpenFileNames(this,"",QDir::currentPath() );

How can I change this so I can select directories as well?

I looked at:

      dialog.setFileMode(QFileDialog::AnyFile);

but I don't get how to use it with my code.

回答1:

This code snippet linked in the comment above solves my issue.

QFileDialog* _f_dlg = new QFileDialog(this);
  _f_dlg->setFileMode(QFileDialog::Directory);
  _f_dlg->setOption(QFileDialog::DontUseNativeDialog, true);

  // Try to select multiple files and directories at the same time in QFileDialog
  QListView *l = _f_dlg->findChild<QListView*>("listView");
  if (l) {
    l->setSelectionMode(QAbstractItemView::MultiSelection);
   }
  QTreeView *t = _f_dlg->findChild<QTreeView*>();
   if (t) {
     t->setSelectionMode(QAbstractItemView::MultiSelection);
    }

  int nMode = _f_dlg->exec();
  QStringList _fnames = _f_dlg->selectedFiles();
