Class enthought.kiva.backend_wx.BaseWxCanvas

API Reference for Enthought Tool Suite 3.0.1

All the WX backends ultimately use the Agg backend to do the actual drawing. However, they all differ in how they construct a memory buffer to hand to Agg. This class defines the basic functionality expected of a Kiva Wx backend canvas. Its concrete methods handle some of the interaction with wx, but it needs to be mixed in with an actual Wx drawable (e.g Window, Frame, GLCanvas, etc.).

Subclasses must implement _create_kiva_gc and blit, and they will most likely provide their own __init__ that calls the Wx drawable-specific base constructor as well as this class's.
