 CalClient

+GTK+ object for communication with personal calendar server.

+  <para>
+    The #CalClient object provides a nice GTK+ wrapper for the CORBA
+    interfaces that are used to communicate between calendar clients
+    and the personal calendar server in the user's Wombat daemon.
+  </para>
+
+  <para>
+    After a #CalClient object is created with cal_client_new(), it
+    should be asked to send a request to the personal calendar server
+    to load or create a calendar based on its URI.  The server will
+    asynchronously notify the client about completion of the request,
+    and will return an appropriate result code; this should be noted
+    by the client with the <link
+    linkend="CalClient--cal-loaded">cal_loaded</link> signal.
+  </para>
+
+  <para>
+    When a client asks the server to update or delete a calendar
+    component from the storage, the server will do so and then notify
+    all the clients about the update or removal.  This is the core of
+    the model/view split between calendar clients and the storage in
+    the personal calendar server.  Clients should watch the <link
+    linkend="calclient-obj-updated">obj_updated</link> and <link
+    linkend="calclient-obj-removed">obj_removed</link> signals on the
+    CalClient objects they create so that they can be notified about
+    changes in the storage.
