We may need to show the navigation arrows in the status pane. This can be done using the following code snippet :

CAknNavigationDecorator* iNaviLabel;
CAknNavigationControlContainer* iNaviContainer; 
CEikStatusPane* sp=(STATIC_CAST(CAknAppUi*,iEikonEnv->EikAppUi()))->StatusPane();
iNaviContainer =(STATIC_CAST(CAknNavigationControlContainer*, 
sp->ControlL(TUid::Uid(EEikStatusPaneUidNavi))));
 
if ( iNaviLabel )
{
iNaviLabel = NULL;
}
 
iNaviLabel = iNaviContainer->CreateNavigationLabelL( _L("label") );
iNaviLabel->MakeScrollButtonVisible(ETrue);
// Activate navi label so that it becomes visible and active
iNaviContainer->PushL( *iNaviLabel );
 
TBool isVisible =iNaviLabel->ScrollButtonVisible();
 
iNaviLabel->SetScrollButtonDimmed(CAknNavigationDecorator::ELeftButton, EFalse);
iNaviLabel->SetScrollButtonDimmed(CAknNavigationDecorator::ERightButton,EFalse);
