2 Using The API

2.1 Adding an observer to the Title pane

The following code snippet shows how to add an observer to the Title pane.

class CFooObserver : public MAknTitlePaneTouchObserver
{
public:
    static CFooObserver* NewL();
    void ConstructL();
    void HandleTitlePaneEventL( TInt aEventId );
private:
    CFooObserver();
};

CFooObserver* CFooObserver::NewL()
{
    CFooObserver* me = new (ELeave) CFooObserver;
    CleanupStack::PushL(me);
    me->ConstructL();
    CleanupStack::Pop(me);
    return me;
}

CFooObserver::CFooObserver()
{
}

void CFooObserver::ConstructL()
{
    CAknTitlePane* titlePane = STATIC_CAST( CAknTitlePane*,
        StatusPane()->ControlL( TUid::Uid( EEikStatusPaneUidTitle ) ) );
    titlePane->SetTitlePaneObserver( this );
}

void CFooObserver::HandleTitlePaneEventL( TInt aEventId )
{
    /*
     * Add your code here.
     */
}

2.2 Limitations of the API

The only supported Title pane event is EAknTitlePaneTapped , which is generated when the Title pane is tapped.
