Help, how to draw a diagram in a window? I need to generate a picture and paste it into a window and draw a curve. It shall be possible to update this picture at a later stage with additional text and curves. How can this be done using MPW Pascal? Source code for the shell is made with Prototyper. What kind of datastructure shall be used for the picture? What is needed so that the window will be able to update itself when it is uncovered? What if I want to use scrollbars in the window?
