Chapter 4. Data and Classes
In this chapter, we will use data and OOP classes using Python 3:
- How to use StringVar()
- How to get data from a widget
- Using module-level global variables
- How coding in classes can improve the GUI
- Writing callback functions
- Creating reusable GUI components
Introduction
In this chapter, we will save our GUI data into tkinter variables.
We will also start using object-oriented programming (OOP) to extend the existing tkinter classes in order to extend tkinter's built-in functionality. This will lead us into creating reusable OOP components.
