I have a 2 classes 1. Main_window another is Load_file_window. When I Press a Load_file option in my Mainwindow, it should open Load_file_window and browse the file and send the file name to my main windows both are 2 different classes. I'm able to browse the file from Load_file_window but when I tried to pass that value to Mainwindow its not happening. How can I proceed with this?
This code will run in windows machine, with Python PyQt5 Module

This is my Main File
I'm expecting the file selected in load file to come into my main windows but its not happening and the windows also not getting closed.
