set-stipple

   

Sets or removes the stipple bitmap. The stipple is only used when the brush's style is  wx:const-stipple (see also set-style), , but setting the bitmap to null turns off the stipple bitmap.

• (send a-wx:brush set-stipple bitmap) -> void
      bitmap :  wx:bitmap% object or null

  Under X Windows, the stipple is a mask between the wx:bitmap object and current colour. Under Windows, the current colour is ignored, and the bitmap colour is used.
