wx:media-canvas%

    Superclass:  wx:canvas%

      A  wx:media-canvas% object manages and views a  wx:media-buffer% object.

• (make-object wx:media-canvas% parent x y width height name style scrolls-per-page buffer) ->  wx:media-canvas% object
      parent :  wx:frame% object
      x = -1 : small integer
      y = -1 : small integer
      width = -1 : small integer
      height = -1 : small integer
      name = "" : string
      style = 0 : small integer
      scrolls-per-page = 100 : small integer
      buffer = null :  wx:media-buffer% object or null

  Most of the arguments here are as with  wx:canvas%. Only the last three arguments are specific to  wx:media-canvas%.

    The style flag is a bitwise combination of

  •  wx:const-mcanvas-no-h-scroll -- doesn't allow horizontal scrolling
  •  wx:const-mcanvas-no-v-scroll -- does't allow vertical scrolling
  •  wx:const-mcanvas-hide-h-scroll -- allows horizontal scrolling with the caret, but doesn't show a horizontal scrollbar
  •  wx:const-mcanvas-hide-v-scroll -- allows vertical scrolling with the caret, but doesn't show a vertical scrollbar

  While vertical scrolling of editor buffers is based on lines, horizontal scrolling and pasteboard vertical scrolling is based on a fixed number of steps per horizontal page. The scrollsPerPage argument sets this value.

  If the canvas is initialized with null for buffer, a buffer can be installed with set-media.
