find-position-in-line

   

Given a graphical location within a line of the buffer, returns the item buffer position at that location.

Only valid when the buffer is viewed.

• (send a-wx:media-edit find-position-in-line i x at-eol? on-it? edge-close?) -> small integer
      i : small integer
      x : inexact real
      at-eol? = null : boxed boolean or null
      on-it? = null : boxed boolean or null
      edge-close? = null : boxed inexact real or null

  See section  for a discussion of the at-eol? argument. The on-it? box is filled with #t if the line actually touches this position, or #f otherwise, unless on-it? is null.

  See find-position for a discussion of edge-close?.
