1 VisContent Instance Data
VisContentClass
provides objects that can be used to head visible trees and interact with the GenView. The VisContent is a necessary class for any application that plans on displaying visible objects in a view.
You should be familiar with visible objects, visible object trees, and the GenView class. These topics can be found in the VisClass chapter and the GenView chapter.
Because
VisContentClass
is a subclass of
VisCompClass
, it inherits all the instance data fields and messages of both that class as well as
VisClass
. You will likely want to read about both of those classes before reading this chapter. You can just read Basic VisContent Usage
if you need a basic VisContent object--that section describes the most basic ways to use the VisContent without understanding its inner workings.

1.1 The VCNI_attrs Field
1.2 Fields That Affect the View

1.4 Fields That Affect Input Events
