1 GenView Overview
The GenView provides a means of displaying data on the screen in a scrollable, sizeable, scalable window. This data may be in the form of a graphics document, a generic object tree, or a visible object tree. If your geode requires a means of displaying data visually, you will most likely want to use a view.
This chapter discusses how to create and use the GenView. You should have a good knowledge of the UI in general, and you should understand the GEOS coordinate system.
