`unobserve`	Unregister an observer callback for the given topic(s).

continuity

continuity¶: Degree of continuity

interpolate¶: Use interpolation method. This will automatically be used if periodic is True or tangents are given.

periodic¶: Whether the spline will be periodic

points¶: List of list of points

proxy¶: A reference to the shape declaration.

create_shape()[source]¶

Create the toolkit shape for the proxy object.

This method is called during the top-down pass, just before the ‘init_shape()’ method is called. This method should create the toolkit widget and assign it to the ‘widget’ attribute.
