set-media

Sets the buffer that is viewed by the canvas, releasing the current buffer (if any). If the new buffer already has an administrator that is not associated with a wx:media-canvas%, then the new buffer is not installed into the canvas.

• (send a-mred:hyper-canvas set-media edit show?) -> void
      edit : a wx:media-edit% object
      show? : boolean

  Calls super-method with the second argument value #f so that the canvas won't be repainted until called to do so in do-tag ; then calls do-tag. (The show? argument here is ignored.)
