Question

我想获取目录路径。

import sys

from PyQt5 import uic
from PyQt5.QtWidgets import QApplication, QFileDialog, QMainWindow


class MainWindow(QMainWindow):

    def __init__(self, parent=None):

        QMainWindow.__init__(self, parent)
        uic.loadUi('view.ui', self)

        self.btn = self.pushButton

        self.btn.clicked.connect(self.get_directory)

    def get_directory(self):

        path = QFileDialog.getExistingDirectory(
                self,
                'Open a folder',
                'H:/',
                QFileDialog.ShowDirsOnly
        )

        print(path)


if __name__ == '__main__':

    app = QApplication(sys.argv)
    myapp = MainWindow()
    myapp.show()
    sys.exit(app.exec_())

它运作完美！

现在，我想使用MVC原理进行同样的操作。

view.py

import sys

from PyQt5 import uic
from PyQt5.QtWidgets import QApplication, QFileDialog, QMainWindow

from controler import GetDirectory


class MainWindow(QMainWindow):

    def __init__(self, parent=None):

        QMainWindow.__init__(self, parent)
        uic.loadUi('view.ui', self)

        self.qfile_dialog = QFileDialog
        self.btn = self.pushButton
        self.cnt = GetDirectory(self)

        self.btn.clicked.connect(self.cnt.get_directory)


if __name__ == '__main__':

    app = QApplication(sys.argv)
    myapp = MainWindow()
    myapp.show()
    sys.exit(app.exec_())

controler.py

class GetDirectory:

    def __init__(self, window):

        self.w = window

    def get_directory(self):

        path = self.w.qfile_dialog.getExistingDirectory(
                self,
                'Open a folder',
                'H:/',
                self.w.qfile_dialog.ShowDirsOnly
        )

        print(path)

然后我得到这个错误：

TypeError：getExistingDirectory（父级：QWidget =无，标题：str = ”，目录：str =”，选项：Union [QFileDialog.Options， QFileDialog.Option] = QFileDialog.ShowDirsOnly）：参数1具有意外的类型“ GetDirectory”

我怎么了？

为什么我在MVC中遇到PyQt5 getExistingDirectory（）错误？
