A method for providing a notification mechanism may include causing provision of a notification bar at an edge of a touch screen display in response to an occurrence of an event where the notification bar provides information indicative of the event, enabling, responsive to user input, extension of the notification bar away from the edge of the touch screen display to display one or more levels of other notification classes in addition to the information indicative of the event, causing presentation of the notification bar to remain in an extended position away from the edge of the touch screen display so as to display one or more levels of notification classes upon cessation of the user input and causing, responsive to exposure of each level that has a subsequent level thereafter, an indication of existence of the subsequent level. A corresponding apparatus and computer program product are also provided.
