These classes provide for all forms of online-help in your application,
with three levels of detail:
Tool Tips and Status Bar message - flyweight help, extremely brief,
entirely integrated in the user interface, requiring little
or no user interaction to invoke.
What's This? - lightweight, but can be
a three-paragraph explanation.
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.
