Hello would you please update your blog, you need to clarify that your code will not work on PyQt5 environment.
The QtGui is not supported in PyQt5, it needs to be changed using QtWidgets instead.
This is the code updated to work with PyQt5
CODE
from PyQt5 import QtGui, QtCore, QtWidgets
import sys, os
import design
class ExampleApp(QtWidgets.QMainWindow, design.Ui_MainWindow):
def init(self, parent=None):
super(ExampleApp, self).init(parent)
self.setupUi(self)
self.btnBrowse.clicked.connect(self.browse_folder)
def browse_folder(self):
self.listWidget.clear()
directory = QtWidgets.QFileDialog.getExistingDirectory(self,"Pick a folder")
if directory:
for file_name in os.listdir(directory):
self.listWidget.addItem(file_name)
def main():
app = QtWidgets.QApplication(sys.argv)
form = ExampleApp()
form.show()
app.exec()
if name == 'main':
main()
CODE

Hi, I followed your instructions but I got following Error can you please help.

Any help would be appreciated.
