-<p>Cone provides the <xref href="GUID-3AC2CDAC-0291-309F-A020-049BC9F2CF90.dita"><apiname>CCoeAppUi</apiname></xref> class as a generic base
-for application user interface development. Uikon provides a specialization, <xref href="GUID-1185F595-0488-3E93-8D60-6B3A1A3AC32E.dita"><apiname>CEikAppUi</apiname></xref>,
-from which concrete application UIs can be derived. UI variant libraries typically
-derive their own AppUi base class from <xref href="GUID-1185F595-0488-3E93-8D60-6B3A1A3AC32E.dita"><apiname>CEikAppUi</apiname></xref> to standardize
-common UI paradigms. <xref href="GUID-3AC2CDAC-0291-309F-A020-049BC9F2CF90.dita"><apiname>CCoeAppUi</apiname></xref> is, therefore, normally
-a 'long way' from the surface of the finished application and knows little
-of the concrete controls or functionality that it contains. </p>
-<p> <xref href="GUID-3AC2CDAC-0291-309F-A020-049BC9F2CF90.dita"><apiname>CCoeAppUi</apiname></xref> provides the following key functionality: </p>

-View Manager (<xref href="GUID-1444A0B4-8828-3EEB-8DC7-C331648A5201.dita"><apiname>CCoeViewManager</apiname></xref>) is encapsulated by <xref href="GUID-3AC2CDAC-0291-309F-A020-049BC9F2CF90.dita"><apiname>CCoeAppUi</apiname></xref> which
-provides a view management API. </p> <p>Views are concrete classes that implement
-the <xref href="GUID-2C5E3F6C-6679-3914-9736-62296E7715A7.dita"><apiname>MCoeView</apiname></xref> interface. Typically they are top-level window-owning
-controls. </p> <p>The significance of views is that they are known of outside
-the application to which they belong. This allows one application to switch,
-or link, directly to a view in another. If the target application is running
-it will be brought to the foreground with the linked view activated. If it
-isn't running it will be started up first. </p> <p>All of the API required
-for implementing, registering, activating, deactivating, linking and observing
-is provided by <xref href="GUID-2C5E3F6C-6679-3914-9736-62296E7715A7.dita"><apiname>MCoeView</apiname></xref> and <xref href="GUID-3AC2CDAC-0291-309F-A020-049BC9F2CF90.dita"><apiname>CCoeAppUi</apiname></xref>. </p> <p>To
-participate fully in the view architecture an application must register at
-least one view. An application with no views may still be linked to using
-the view architecture. It registers itself with a <codeph>TVwsViewId</codeph> containing
-its application UID. Obviously it will not receive activation and deactivation
-events but will trigger view switch events in other applications' views. </p> <p>An
-application may opt out of the view architecture (see <xref href="GUID-42003A58-F3FE-3FEB-8019-A819B860C64B.dita#GUID-42003A58-F3FE-3FEB-8019-A819B860C64B/GUID-DC2562EE-67C1-3FD3-8A43-FA9F1B02DE07"><apiname>TApaCommand::EApaCommandRunWithoutViews</apiname></xref> and <xref href="GUID-42003A58-F3FE-3FEB-8019-A819B860C64B.dita#GUID-42003A58-F3FE-3FEB-8019-A819B860C64B/GUID-84C2A808-B397-3656-A422-E1E10FE04330"><apiname>TApaCommand::EApaCommandBackgroundAndWithoutViews</apiname></xref>) </p> </li>
