A list of the following form:
list ( [ nil | list ( x_horzMin x_horzMax x_horzValue x_horzSliderSize ) ] [ nil | list( x_vertMin x_vertMax x_vertValue x_vertSliderSize ) ] )
The first element of the list provides information about the horizontal scroll bar; the second element of the list provides information about the vertical scroll bar. If the first element is nil, the form or scroll region field does not have a horizontal scroll bar; if the second item in the list is nil, the form or scroll region field does not have a vertical scroll bar.
x_horzMin and x_vertMin are the minimum pixel position (usually 0); x_horzMax and x_vertMax are the horizontal or vertical pixel size of the form or scroll region field; x_horzValue and x_vertValue are the current values of the scroll bars; and x_horzSliderSize and x_vertSliderSize are the visible areas of the form or scroll region field.
The maximum values for the l_newValues argument of the hiSetScrollBarValue function are:
x_horzMax - x_horzSliderSize and x_vertMax - x_vertSliderSize.
