Provide a base class for all Bokeh widget models.

class Widget(**kwargs)[source]

Bases: bokeh.models.layouts.LayoutDOM

A base class for all interactive widget types.


This is an abstract base class used to help organize the hierarchy of Bokeh model types. It is not useful to instantiate on its own.
