Abstract:

A method and system for managing the active area of a touch-sensitive display is disclosed. A request to resize the active area of a touch-sensitive display is received from a user in the form of a user gesture. The relationship of the current dimensions of the active area to the inside dimensions of a bezel associated with the touch-sensitive display is determined. The request is then processed to initiate active area resizing operations. If the dimensions of the active area are coincident with the inside dimensions of the bezel, then the dimensions of the active area can be reduced. If the dimensions of the active area are not coincident with the inside dimensions of the bezel, then the dimensions of the active area can be increased.
