python - 如何使用 KFileDialog 选择多个目录？

Question

使用PyKDE4.kio 选择多个文件我可以使用KFileDialog.getOpenFileNames(而不是KFileDialog.getOpenFileName)。如果要选择多个目录怎么办？只有 KFileDialog.getExistingDirectory。

使用 KFileDialog.getOpenFileNames(filter = 'inode/directory') 并选择多个文件夹显示错误:

More than one folder has been selected and this dialog does not accept folders, so it is not possible to decide which one to enter. Please select only one folder to list it.

我从 JohannesMunk on qtcentre.org 找到了解决方案并将其翻译成 python

import sys
from PyQt5.QtWidgets import (QFileDialog, QAbstractItemView, QListView,
                             QTreeView, QApplication, QDialog)

class getExistingDirectories(QFileDialog):
    def __init__(self, *args):
        super(getExistingDirectories, self).__init__(*args)
        self.setOption(self.DontUseNativeDialog, True)
        self.setFileMode(self.Directory)
        self.setOption(self.ShowDirsOnly, True)
        self.findChildren(QListView)[0].setSelectionMode(QAbstractItemView.ExtendedSelection)
        self.findChildren(QTreeView)[0].setSelectionMode(QAbstractItemView.ExtendedSelection)

qapp = QApplication(sys.argv)
dlg = getExistingDirectories()
if dlg.exec_() == QDialog.Accepted:
    print(dlg.selectedFiles())
