Help System

These classes provide online-help for your application, with three levels of detail:

  1. Tool Tips and Status Bar message - flyweight help, extremely brief, entirely integrated in the user interface, requiring little or no user interaction to invoke.
  2. What's This? - lightweight, but can be a three-paragraph explanation.
  3. Online Help - can encompass any amount of information, but is typically slower to call up, somewhat separated from the user's work, and often users feel that using online help is a digression from their real task.
