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.

QToolTip

The QToolTip class provides tool tips (balloon help) for any widget.

QWhatsThis

The QWhatsThis class provides a simple description of any widget, i.e. answering the question "What's This?".

QStatusBar

The QStatusBar class provides a horizontal bar suitable for presenting status information.
