Pyqt: How to show a QFileDialog?

**robgeek** · 9th October 2016, 15:24

Hi!

I would like to choose a path for a file that will be downloaded from internet. To do that I tried to create a button, when pressed will open a QFileDialog so I can choose the path. To make my initial GUI i'm using Qt Designer 5.7 and pyqt5.

The output when i hit "Folder" button:

Traceback (most recent call last):
File "teste.py", line 49, in destination
self.folderPath = QtWidgets.QFileDialog.getExistingDirectory(self, 'Select folder');
TypeError: getExistingDirectory(parent: QWidget = None, caption: str = '', directory: str = '', options: Union[QFileDialog.Options, QFileDialog.Option] = QFileDialog.ShowDirsOnly): argument 1 has unexpected type 'Ui_MainWindow'
Aborted (core dumped)

Qt Code:

Switch view

from PyQt5 import QtCore, QtGui, QtWidgets
#...
self.destinoButton.clicked.connect(self.destination)
#...
    def destination( self ):
        self.folderPath = QtWidgets.QFileDialog.getExistingDirectory(self, 'Select folder');

from PyQt5 import QtCore, QtGui, QtWidgets
#...
self.destinoButton.clicked.connect(self.destination)
#...
    def destination( self ):
        self.folderPath = QtWidgets.QFileDialog.getExistingDirectory(self, 'Select folder');

To copy to clipboard, switch view to plain text mode

How can I fix it?
