line-start-position

Returns the first position of the given line. Lines are numbered starting with 0.

Calling this method may force the recalculation of location information if a maximum width is set for the buffer, even if the buffer currently has delayed refreshing (see refresh-delayed?). If the buffer is not viewed (see Basic Organization) and a maximum width is set for the buffer, this method ignores the maximum width if the buffer has never been viewed, otherwise using the line breaks from the most recent view of the buffer (unadjusted by any insertions or deletions).

• (send a-wx:media-edit line-start-position line visible?) -> small integer
      line : small integer
      visible? = #t : boolean

  If there are fewer than line-1 lines, the start of the last line is returned. If line is less than 0, then the start of the first line is returned.

  If the line starts with invisible items and visible? is not #f, the first position past the invisible items is returned.
