abstract class HelpViewer
extends Object
The abstract super class of all help text viewer classes. It gets its texts from a HelpTexts instance that is passed to the constructor of this class. This way, the texts that are displayed are independent of the way they are displayed, so the same texts can be used in several HelpViewers specialized in several contexts.
