AppUi flag EAknEnableMSK

The MSK feature is application-specific and the application must enable MSK by setting EAknEnableMSK flag in the BaseConstructL method of CAknViewAppUi or CAknAppUi:

void CAknMyAppUi::ConstructL()
    {
    // MSK disabled
    BaseConstructL( EAknEnableSkin );

    // MSK enabled
    BaseConstructL( EAknEnableSkin | EAknEnableMSK );

The application-specific MSK state can be queried by using:

EXPORT_C TBool AknLayoutUtils::MSKEnabled()
