mred:testable-canvas%

Superclass: wx:canvas%

• (make-object mred:testable-canvas% parent x y width height style name) -> mred:testable-canvas% object
      parent : wx:frame% object or wx:panel% object
      x = -1 : small integer
      y = -1 : small integer
      width = -1 : small integer
      height = -1 : small integer
      style = 0 : small integer
      name = "canvas" : string

  If x, y, width or height is -1, a default position/size is selected. The default may be platform-specific.

  The style argument is a bitwise-ior combination of the following flags:

  • wx:const-border -- gives the canvas a thin border
  • wx:const-hscroll -- enables horizontal scrolling
  • wx:const-vscroll -- enables vertical scrolling
  (Use 0 for no flags.) The wx:const-hscroll and wx:const-vscroll flags create a canvas with an initially inactive scrollbar. The scrollbar is activated with set-scrollbars.

  The name argument is used to associate a name with the canvas, allowing the application user to set X Windows resource values for each individual canvas.
