Hi, I’ve been reading classic design patterns in https://refactoring.guru, however I can’t find some specific examples on how to design a simple menu system.
Say you have a hardware screen, and some up+down+enter input buttons. How would you design that in pseudocode? do you have any videos or posts to recommend?
I imagine having these classes:
- list of widgets
- render() loops through widget’s render()
- has the input button callbacks
Inside Screen might start a thread to update the display, rendering all widgets.
However, I don’t understand how the Screen & Controller could communicate each other to display.
This is not a great example, but I’m sure there are patterns for something similar.
