set-lazy-refresh

   

Sets tenables or disables lazy-refresh mode. In lazy-refresh mode, the canvas's refresh method is called when the window needs to be updated, rather than on-paint. By default, a  wx:media-canvas% object is not in lazy-refresh mode.

• (send a-wx:media-canvas set-lazy-refresh on?) -> void
      on? : boolean

  If on? if #f, lazy-refresh mode is disabled, otherwise it is enabled.
