scroll-to-position

   

Scrolls the buffer so that a given position is visible.

• (send a-wx:media-edit scroll-to-position start at-eol? end bias) -> boolean
      start : small integer
      at-eol? = #f : boolean
      end = -1 : small integer
      bias = 0 : small integer

  See section  for a discussion of at-eol?. If end is not -1 and not the same as start, then the range start to end is made visible and at-eol? is ignored.

  When the range cannot fit in the visible area, bias indicates which end of the range to display. When bias is -1, then the start of the range is displayed. When bias is 1, then the end of the range is displayed.

  If the buffer is scrolled, then the buffer is redrawn and the return value is #t; otherwise, the return value is #f.
