Python - PyQt5 how to take file as a input? - python-3.x

Question

There is screenshot attached below:So basically i want to take file as a input(i.e suffix_list.txt) instead of specifying file location inside the function and when i clicked action button i need execute a output inside QtTextEdit
I tried something but i can't get it. Please help me out. I'm new to PyQt5Thanks

Answer 1

The two main problems you have are that you do not call your file_open method and you are supplying an instance of Ui_MainWindow to your file dialog when it needs to be an instance of MainWindow. Here is how to fix this:
def retranslateUi(self, MainWindow):
self.main_window = MainWindow
# your code here
self.actionOpen_File.triggered.connect(self.file_open)
def file_open(self):
name, _ = QtWidgets.QFileDialog(self.main_window, 'Open File', options=QtWidgets.QFileDialog.DontUseNativeDialog)
# your code here
There are, however, some problems outside the scope of this question in your code structure that will make this difficult to expand upon.

Thanks everyone <
