+<p>Code example: </p>
+<p>First define a data structure for the event data:</p>
+<codeblock id="GUID-BBC9DCFA-F46C-4AC9-BC7F-B1A2DB39963A" xml:space="preserve">class TEventsEventType
+    {
+    public:

+</codeblock>
+<p>Then create an event and send it to all window groups:</p>
+<codeblock id="GUID-0E8CE3D4-19F2-46D6-9A22-9A7EBC73F5C5" xml:space="preserve">// Create a window server event
+TWsEvent event;
+TEventsEventType eventType;
+// Set event data. eventType.data = KData;
+event.SetType( ETestEvent1 ); // set event type
+event.SetTimeNow(); // set the event time
+event.SetHandle( iWsSession.WsHandle() ); // set window server handle
+*( TEventsEventType* )( event.EventData() ) = eventType; // set event data
+// Send the created event
+User::LeaveIfError( iWsSession.SendEventToAllWindowGroups( event ) );
+</codeblock>
+<p>Catch the event using the following method:</p>
