<p>The term <i>control</i> refers to a rectangular area of the display

that may respond to user input events. A control provides a means of access

to a window, which means it can be drawn onto the window and receive input.</p>

<p>Controls are derived from <parmname>CCoeControl</parmname>.</p>

<p>Examples of controls include:</p>

<ul>

<li><p>buttons</p></li>

<li><p>menus</p></li>

<li><p>text edit boxes</p></li>

<li><p>main panes that display application specific data</p>

</li>

</ul>
