Huh? Bresenham's line drawing algorithm doesn't work by finding the midpoint. It is possible to draw a line by recursively finding the midpoint, but that's just not how Bresenham did it.
PalmOS provides some drawing operations including a filled rectangle and a rectangular frame. These can be used as a foundation on which to build routines for drawing other things. For example, Palm OS doesn't have a circle drawing operation, but you can write one yourself. Once drawn on the screen, the OS doesn't know anything about these objects. If you want the user to be able to tap on them and resize them, you need to manage all that. -- Peter Epstein -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
