<concept id="GUID-F2397B5A-0700-46D5-8E07-CBB9F769DA01" xml:lang="en"><title>Getting

user selection from the choice list</title><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>Every time the choice list's status changes, e.g. when the user opens or

closed the list or selects an item from the list, the client application is

informed through the <codeph>MCoeControlObserver</codeph> interface. </p>

<p>Notifications are received by the <codeph>HandleControlEventL</codeph> callback

function in the class <codeph>MCoeControlObserver</codeph>. The event is <codeph>EEventStateChanged</codeph>.</p>

<p>After receiving the event, the client application can use the choice list's <codeph>SelectedIndex</codeph> method

to request if the selection has changed. </p>
