<hr><a name="_details"></a><h2>Detailed Description</h2>
The TStatusLine object is a specialized view, usually displayed at the bottom of the screen. Typical status line displays are lists of available hot keys, displays of available memory, time of day, current edit modes, and hints for users.
<p>
Status line items are <a class="el" href="classTStatusItem.html">TStatusItem</a> objects which contain data members for a text string to be displayed on the status line, a key code to bind a hot key, and a command to be generated if the displayed text is clicked on with the mouse or the hot key is pressed.
