tomwalters@0: % sets the range and the step size, so that the width of the slider is OK
tomwalters@0: % a slidereditcontrol consists of a slider and an edit object, that are 
tomwalters@0: % related. When one value changes, the other also changes.
tomwalters@0: % The combination has the following variables:
tomwalters@0: % sliderhandle - the handle of the slider control
tomwalters@0: % edithandle - the handle of the edit control
tomwalters@0: % minvalue - the minimum value allowed
tomwalters@0: % maxvalue - the maximum allowed value
tomwalters@0: % (current_value - the current value)
tomwalters@0: % is_log - whether the slider reponds logarithmically
tomwalters@0: % editscaler - a number, that is multiplied to the edit control (to make ms of secs)
tomwalters@0: % nreditdigits - the number of digits in the edit control
tomwalters@0: 
tomwalters@0: % works only for linear sliders (yet)
