Method and system for dynamically manipulating values associated with graphical elements displayed within a graphical user interface

摘要

A method and system for dynamically manipulating values associated with graphical elements displayed within a graphic interface of a data-processing system. Initially a pointer element associated with a pointing device is displayed within the graphic interface, such that the pointer element is capable of movement in multiple directions in response to movement of the pointing device. A trackslide element and a moveable slider are displayed within the graphic interface. The moveable slider permits users to dynamically decrease or increase values associated with the trackslide element, such that the moveable slider is constrained to move only in a first direction along the trackslide element. The pointer element is then graphically attached to the moveable slider. Thereafter movement of the pointing device is translated into movement of the moveable slider in response to movement of the pointing device in the first direction while ignoring movement of the pointing device in the second direction, such that the moveable slider may be accurately and efficiently moved along the trackslide element without requiring the pointing device to be constrained to movement in a single direction.
