#TODO: This needs to run in a thread but Qt really doesn't want it to. There are two ways around this:
# - create the QtWidgets.QApplication inside a thread and run all QT stuff inside that thread
# - make a generic wrapper for window mainloop that will always run in the main thread while the actual main control flow of the program gets moved to another thread
# There are some issues with these workarounds though; mainly that QT isn't thread safe.
# I really want to keep QT running in its own thread because I want to retain the ability to arbitrarily spawn and manipulate windows while other windows are running.
# Another issue that is probably easily worked around / fixed is that app.exec() will return once all running windows are closed.
# Idea for a workaround for both:
# Maybe Qt has scheduled events in which case a scheduled polling event could run a function inside the Qt thread that fetches commands and executes them.
# This could work by passing (lambda) functions through a Communication object.
