Inside Macintosh: QuickDraw GX Programmer's Overview / Part 1 - Getting Started With QuickDraw GX

Chapter 2 - A Quick & Easy Sample Program
This chapter gives a brief introduction to programming with QuickDraw GX. In this chapter, there is all the QuickDraw GX code you need to create, modify, draw, and print a shape.
This chapter is not meant as a comprehensive introduction, but rather as
a streamlined view of programming with QuickDraw GX. The concepts presented in this chapter are discussed very briefly here. You can find more detailed information in Chapter 3, "Using QuickDraw GX Objects."
Specifically, this chapter shows you how to use QuickDraw GX to

create a curve shape
set the geometry of the curve
set the pen width of the curve
set the color of the curve
rotate the curve
draw the curve to a Macintosh window
print the curve to the user's default printer
examine the curve shape using GraphicsBug

With the rich programming interface provided by QuickDraw GX, each of these tasks could be implemented in a number of different ways. This section describes one simple implementation for each task.
