get-snip-position-and-location

Gets a snip's item position and top left display location in buffer coordinates. The return value is #t if the snip is found, #f otherwise.

When location information is requested: The result is only valid when the buffer is viewed (see Basic Organization). Calling this method may force the recalculation of location information, even if the buffer currently has delayed refreshing (see refresh-delayed?).

• (send a-wx:media-edit get-snip-position-and-location snip pos x y) -> boolean
      snip : wx:snip% object
      pos : boxed small integer or null
      x = null : boxed inexact real or null
      y = null : boxed inexact real or null

  The pos box is filled with starting position of snip, unless pos is null. The x box is filled with left location of snip in buffer coordinates, unless x is null. The y box is filled with top location of snip in buffer coordinates, unless y is null.
