About View Device Objects
A view device object represents an output device such as a monitor or printer. When a shape is drawn, it appears on a view device, although its actual drawing destination is a view port. The intersection of the view port and view device determine where and how much of the shape is drawn. Figure 7-11 shows how a single view device can display more than one view port, and how a single view port can overlap more than one view device.Figure 7-11 View ports overlapping view devices
For drawing, you do not need to be concerned whether a view port overlaps one or more separate view devices; you just draw to the view port and QuickDraw GX handles it for you. On the other hand, if a view port does not intersect any device, the shapes drawn to the view port are not rendered at all.
