The drawing area and canvas

The canvas provides an infinite space upon which you can create and manipulate viewports. The drawing area is a window into the visible part of the canvas.

You can access the canvas area using the following statement:

canvas = getAFXApp().getAFXMainWindow().i_getCanvas()
The “i_” in the method name indicates that this is an internal method that you should not normally use—it is expected that only the GUI infrastructure needs to access this method.
