Python/Dash Callbacks

[elliothershberg]

There is a general API for alerting Python Dash callbacks that are listening for changes. It involved calling it like this:

onChange={
    /*
     * Send the new value to the parent component.
     * setProps is a prop that is automatically supplied
     * by dash's front-end ("dash-renderer").
     * In a Dash app, this will update the component's
     * props and send the data back to the Python Dash
     * app server if a callback uses the modified prop as
     * Input or State.
     */
     e => setProps({ value: e.target.value })
}

Note: I'm not sure how useful this is, and it probably would only apply to people using it in a Dash app, not a notebook.
