<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 <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-cpp/Control_Environment/CCoeControlClass.html" format="application/java-archive"><parmname>CCoeControl</parmname></xref>.</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>
