This code was developed specifically for the Adafruit 128x64 OLED Bonnet for the Raspberry Pi.
It can, however, be run in a tkinter window for prototyping ideas without the required hardware.
The architecture design was meant to provide extensible components, a highly configurable nested menu system, settings interfaces, and customizable components for displaying and manipulating data.
There is a central ApplicationState class that manages event dispatching and listening. It takes a configuration instance of ApplicationConfig that contains initialized components and application logic.
When a Button input is received to the ApplicationState.update function, it passes the event through to the currently displayed component, which should render a TkImage to be emitted back to the ApplicationState instance by calling emit_event('image', image). This image will be forwarded to whichever display medium is connected.
There are several other events that can be emitted with the emit_event() function of the Component subclasses.
