QFileDialog:选择目录和文件 [英] QFileDialog: Selecting directories and files

问题描述

我正在使用以下代码构建文件名的qstringlist:

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

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

如何更改此设置，以便我也可以选择目录?

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

我看着:

      dialog.setFileMode(QFileDialog::AnyFile);

但是我不知道如何在我的代码中使用它.

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

推荐答案

上面注释中链接的此代码段解决了我的问题.

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();
