# Help System

Classes used to provide online-help for applications. These classes provide for all forms of online-help in 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.
