get-snip-location

Gets the graphical location of the given snip. If the snip is found in the buffer, #t is returned; otherwise, #f is returned.

The result is only valid when the buffer is viewed (see Basic Organization). For wx:media-edit% objects, 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?).

• (send a-wx:media-buffer get-snip-location thesnip x y bottom-right?) -> boolean
      thesnip : wx:snip% object
      x = null : boxed inexact real or null
      y = null : boxed inexact real or null
      bottom-right? = #f : boolean

  The x box is filled with the x-coordinate of the snip's location, unless x is null. The y box is filled with the y-coordinate of the snip's location, unless y is null.

  If bottom-right? is not #f, the values in the x and y boxes are for the snip's bottom right corner instead of its top-left corner.
