Select QFileDialog pyqt5 中的一个文件或文件夹
Select a file or a folder in QFileDialog pyqt5
我的脚本目前正在使用 QtWidgets.QFileDialog.getOpenFileNames() 让用户 select 文件在 Windows 资源管理器中。现在我想知道是否有办法让它们 select 也可以是文件夹，而不仅仅是文件。有一些类似的帖子，但其中 none 提供了可行的解决方案。我真的不想使用 QFileDialog 文件浏览器来解决这个问题。
QFileDialog 本身不允许这样做。唯一的解决办法是创建自己的实例，做一些小的“修补”。
请注意，为了实现此目的，您不能使用 OS 的 原生 对话框，因为 Qt 几乎 没有 [=20] =] 控制他们；这就是 dialog.DontUseNativeDialog 标志的原因，它是强制性的。
以下代码与静态方法一样有效，returns 选定的项目（或 none，如果对话框被取消）。
def getOpenFilesAndDirs(parent=None, caption='', directory='',
filter='', initialFilter='', options=None):
def updateText():
# update the contents of the line edit widget with the selected files
selected = []
for index in view.selectionModel().selectedRows():
selected.append('"{}"'.format(index.data()))
lineEdit.setText(' '.join(selected))
dialog = QtWidgets.QFileDialog(parent, windowTitle=caption)
dialog.setFileMode(dialog.ExistingFiles)

dialog.setOptions(options)
dialog.setOption(dialog.DontUseNativeDialog, True)

# by default, if a directory is opened in file listing mode,
