PyQt - QFileDialog - directly browse to a folder?
提问by YaronGh
Is there any way to directly browse to a folder using QFileDialog?
有没有办法使用 QFileDialog 直接浏览到文件夹？
Meaning, instead of double clicking on each folder while navigating to the destination folder, simply enter the path somewhere or use a hotkey like the one (Shift+Command+G) in Finder on Mac OS X.
这意味着，无需在导航到目标文件夹时双击每个文件夹，只需在某处输入路径或使用 Mac OS X 上 Finder 中的热键（Shift+Command+G）即可。
Thanks!
谢谢！

filter = "Wav File (*.wav)"
self._audio_file = QtGui.QFileDialog.getOpenFileName(self, "Audio File",
"/myfolder/folder", filter)
self._audio_file = str(self._audio_file)

If you use the static QFileDialogfunctions, you'll get a nativefile-dialog, and so you'll be limited to the functionality provided by the platform. You can consult the documentation for your platform to see if the functionality you want is available.
如果您使用静态QFileDialog函数，您将获得一个本机文件对话框，因此您将受限于平台提供的功能。您可以查阅您平台的文档以查看您想要的功能是否可用。
If it's not available, you'll have to settle for Qt's built-infile-dialog, and add your own features. For your specific use-case, this should be easy, because the built-in dialog already seems to have what you want. It has a side-barthat shows a list of "Places" that the user can navigate to directly. You can set your own places like this:
如果它不可用，您将不得不接受 Qt 的内置文件对话框，并添加您自己的功能。对于您的特定用例，这应该很容易，因为内置对话框似乎已经有了您想要的东西。它有一个侧栏，显示用户可以直接导航到的“地点”列表。您可以像这样设置自己的位置：
dialog = QtGui.QFileDialog(self, 'Audio Files', directory, filter)
dialog.setFileMode(QtGui.QFileDialog.DirectoryOnly)
dialog.setSidebarUrls([QtCore.QUrl.fromLocalFile(place)])
if dialog.exec_() == QtGui.QDialog.Accepted:
self._audio_file = dialog.selectedFiles()[0]

Here's a convenience function for quickly making an open/save QFileDialog.
这是一个快速打开/保存的便利功能QFileDialog。
from PyQt5.QtWidgets import QFileDialog, QDialog
from definitions import ROOT_DIR
from PyQt5 import QtCore
def FileDialog(directory='', forOpen=True, fmt='', isFolder=False):
options = QFileDialog.Options()
options |= QFileDialog.DontUseNativeDialog
options |= QFileDialog.DontUseCustomDirectoryIcons
dialog = QFileDialog()
dialog.setOptions(options)
dialog.setFilter(dialog.filter() | QtCore.QDir.Hidden)
# ARE WE TALKING ABOUT FILES OR FOLDERS
if isFolder:
dialog.setFileMode(QFileDialog.DirectoryOnly)
else:
dialog.setFileMode(QFileDialog.AnyFile)
# OPENING OR SAVING
dialog.setAcceptMode(QFileDialog.AcceptOpen) if forOpen else dialog.setAcceptMode(QFileDialog.AcceptSave)
# SET FORMAT, IF SPECIFIED
if fmt != '' and isFolder is False:
dialog.setDefaultSuffix(fmt)
dialog.setNameFilters([f'{fmt} (*.{fmt})'])
# SET THE STARTING DIRECTORY
if directory != '':
dialog.setDirectory(str(directory))
else:
dialog.setDirectory(str(ROOT_DIR))
if dialog.exec_() == QDialog.Accepted:
path = dialog.selectedFiles()[0] # returns a list
return path
else:
return ''

In PyQt 4, you're able to just add a QFileDialogto construct a window that has a path textfield embedded inside of the dialog. You can paste your path in here.
在 中PyQt 4，您可以只添加一个QFileDialog来构造一个窗口，该窗口在对话框内嵌入了一个路径文本字段。您可以在此处粘贴您的路径。
QtGui.QFileDialog.getOpenFileName(self, 'Select file') # For file.
For selecting a directory:
选择目录：
QtGui.QFileDialog.getExistingDirectory(self, 'Select directory')
Each will feature a path textfield:
每个都有一个路径文本字段：

Use getExistingDirectorymethod instead:
改用getExistingDirectory方法：
from PyQt5.QtWidgets import QFileDialog
dialog = QFileDialog()
foo_dir = dialog.getExistingDirectory(self, 'Select an awesome directory')
print(foo_dir)

Below you'll find a simple test which opens directly the dialog at a certain path, in this case will be the current working directory. If you want to open directly another path you can just use python's directory functions included in os.path module:
下面你会发现一个简单的测试，它直接在特定路径打开对话框，在这种情况下将是当前工作目录。如果你想直接打开另一个路径，你可以使用 os.path 模块中包含的 python 目录函数：
import sys
import os
from PyQt4 import QtGui
def test():
filename = QtGui.QFileDialog.getOpenFileName(
None, 'Test Dialog', os.getcwd(), 'All Files(*.*)')
def main():
app = QtGui.QApplication(sys.argv)
test()
sys.exit(app.exec_())
if __name__ == "__main__":
main()
