set-position-bias-scroll in text%

Like set-position, but a scrolling bias can be specified.

• (send a-text set-position-bias-scroll bias start end ateol? scroll? seltype) -> void
     bias : symbol in '(start-only start none end end-only)
   start : exact non-negative integer
     end = 'same : exact non-negative integer or 'same
   ateol? = #f : boolean
     scroll? = #t : boolean
     seltype = 'default : symbol in '(default x local)

  The possible values for bias are:

  • 'start-only -- only insure that the starting position is visible

  • 'start -- if the range doesn't fit in the visible area, show the starting position

  • 'none -- no special scrolling instructions

  • 'end -- if the range doesn't fit in the visible area, show the ending position

  • 'end-only -- only insure that the ending position is visible
