+## Displays a selection scale (range widget) window.
+## Allows the user to choose a parameter within the set ranges, and sets
+## default value, and step sizes.
+## The variable @var{title} sets the title of the window.
+## The variable @var{text} sets the label of the range widget.
+## The other arguments @var{value}, @var{minval},@var{maxval},
+## @var{step}, @var{print_partial}, and @var{hideval}.
+## The range widget can be used to select anywhere from @var{minval} to
+## @var{maxval} values in increments of @var{step}. The variable
+## @var{print_partial} and @var{hideval} are boolean flags to partial
+## and hidden views of the value on the range widget.
+## The first 3 parameters are essential, while the remaining parameters
+## @var{minval}, @var{maxval},@var{step},@var{print_partial},@var{hideval} if
+## not specified take on default values of 0,100,1,false,false
+## respectively.
