Abstract: A method for displaying a gain control interface having a gain level display with non-linear gain levels. The gain level display has a first end having an associated first pixel offset value and a second end having an associated second pixel offset value. A range of pixel offset values span from the first pixel offset value through the second pixel offset value. The method includes receiving a plurality of pixel offset values in the range of pixel offset values, calculating a gain level value for each of the plurality of pixel offset values (whereby a difference between two pixel offset values of two gain level values having a gain level difference is not equal to a difference of two pixel offset values of any other two gain level values having the same gain level difference), and mapping a gain level value to a pixel offset value.

Abstract: A system and method for collecting and dispatching selected events in an application program comprises an application routine which registers selected events of interest to form a series of handler tables, an event manager which evaluates each new event as it occurs to determine whether any new events are registered in the series of handler tables, and a series of event handlers for responsively handling new events which are registered in the series of handler tables.
