+GLib events in Symbian UI applications</title><shortdesc>Symbian UI applications run an event loop that is based on <apiname>CActiveScheduler</apiname>.
+The active scheduler is started by the UI framework immediately after the
+UI has been created (that is after <codeph>ConstructL()</codeph> of <apiname>CEikAppUi</apiname>-derived
+class).</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>To receive events from GLib event sources, an active object can be added
+to the active scheduler especially for this purpose. The active object runs
+one iteration of the glib event loop every time it gets scheduled.</p>
+<note>The scheduling logic in the sample code provided below is based on a
+simple timer; more complex scheduling logic can be implemented depending on
+the requirement of the application.</note>
