+if the device does not support touch.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>Typical cases where <parmname>AknLayoutUtils::PenEnabled()</parmname> might
+be useful include:</p>
+<ul>
+<li><p>In the component’s constructor to skip the creation of touch-only component
+controls.</p></li>
+<li><p>In the component’s <parmname>HandleResourceChange</parmname>, create
+touch-only component controls if the layout is switched from a non-touchable
+to a touchable one. Touch-only component controls should not be deleted.</p></li>
+<li><p>In the component’s drawing code.</p></li>
+</ul>
+<note><p><codeph>AknLayoutUtils::PenEnabled()</codeph> is supported from S60
+3rd Edition, FP1, onwards.</p></note>
