This program is a basic pizza ordering program with seven topping options, four size options, and five crust options. It pulls the options from a database and populates the GUI on start.
I connected the images saved in the program to the strings associated with each topping. I used a recursive method to stack the topping images that will update each time a topping selection is made. The recursive method was the only solution I found that would restack the images without a blank space when a topping was deselected. It is working really well but I wanted to make it available for review.
The recursive method I used for the GUI is on the bottom of the code. There is also a lot of code written for the check box buttons. I'm not sure if I could have made that any shorter.
This is how the program looks:
