Inside Macintosh: Imaging With QuickDraw /

Chapter 8 - Cursor Utilities

This chapter describes the utilities that your application uses to draw and manipulate the cursor on the screen. You should read this chapter to find out how to implement cursors in your application. For example, you should change the arrow cursor to an I-beam cursor when it's over text and to an animated cursor when a medium-length process is under way.

Cursors are defined in resources; the routines in this chapter automatically call the Resource Manager as necessary. For more information about resources, see the chapter "Resource Manager" in Inside Macintosh: More Macintosh Toolbox. Color cursors are defined in resources as well, though they use Color QuickDraw. For information about Color QuickDraw, see the chapter "Color QuickDraw" in this book.
