      The Symbian platform provides AVKON controls, which are a convenient
set of UI components designed specifically for devices based on the Symbian
platform.

     </ul>
     <p>
      All of the AVKON resources listed above, except dialogs, queries and
notes, are non-window-owning controls. This means that they cannot exist on
the screen without being inside another

     </p>
     <div class="note">
      <span class="notetitle">
       Note:
      </span>
      <p>
       Since AVKON UI resources scale automatically according to screen resolution
and orientation, it is recommended that you consider using AVKON or AVKON-derived
components in your application UI as they may require less implementation
effort. Custom

        </span>
       </a>
       -derived controls may require
additional efforts to support
