The FigureCanvasWx
constructor gained a canvas_class keyword-only
parameter which specifies the canvas class that should be used. This
parameter will become required in the future. The get_canvas
method,
which was previously used to customize canvas creation, is deprecated. The
FigureFrameWxAgg
and FigureFrameWxCairo
subclasses, which overrode
get_canvas
, are deprecated.
