Write a simple graphics editor that allows users to add a mixture of shapes (ellipses, rectangles, and lines in different colors) to a panel. Supply commands to load and save the picture.
Basically it wants a program with a buttons for New, Load, Save, Rectangle, Line, Ellipse, Red, Green, Blue, Yellow. You press a button for a shape, and then press a button for a color, and the program draws it. The location is always the same for each shape, as it creates a face.
I'm having a problem however. I click the button for my shape, and then click the color, and nothing happens. No matter what buttons I click, I get no results.
My code:
