Upgrade 01: PyQt6 Desktop App Template

This demo program shows another way to implement the Desktop App Template using modularized approach(I created the import.py to handle import common libraries of the the window files(splash, login, mainw), a sidebar menu has been added which is from the previous post "Create Treeview with PyQt6" and I added a progress bar at the newly added status of the login screen of which code is derrived from my previous post "Progressbar with PyQt6".  If you prefer the old version you may still access it with the original post.

The Output:
