Hello,
I have yet another question, but this one entails replacing the current screen/window with a new one when it is called.
I'm trying to have my AdminMenu.py(A PyQT GUI) open on the same windows after the user has logged in on the LoginScreen.py(A PyQT GUI).
How can I achieve this?
Do I just call the class Ui_MainDisplay(object):?
I looked online but I can't find many tutorials on this, so any help is greatly appreciated.
Thanks in advance.
The validate chunk of my Login Screen Code which will take the user to the appropriate menu (I'm only focusing on adminMenu for now):
