<div class="descr"> <a name="details"></a>
<a name="help-system"></a><p>These classes provide for all forms of online-help in your application, with three levels of detail:</p>
<ol class="1">
<li>Tool Tips and Status Bar message - flyweight help, extremely brief, entirely integrated in the user interface, requiring little or no user interaction to invoke.</li>
<li>What's This? - lightweight, but can be a three-paragraph explanation.</li>
<li>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.</li>
</ol>
