Help System

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.

QAssistantClientThe QAssistantClient class provides a means of using Qt Assistant as an application's help tool.
QHelpEventThe QHelpEvent class provides an event that is used to request helpful information about a particular point in a widget.
QStatusBarThe QStatusBar class provides a horizontal bar suitable for presenting status information.
QStatusTipEventThe QStatusTipEvent class provides an event that is used to show messages in a status bar.
