Interact with the current Deck, Slide from a kernel #42

Open bollwyvl opened 1 year ago

Elevator Pitch

Allow for kernels to be notified when data related to a deck changes, such as its current active index, possible indices, scroll position, etc.

Motivation

This would allow for interesting

Design Ideas

Add jupyterlab_deck.widgets.Deck, a subclass of ipywidgets.Widget
- add an (optional) depdendency on ipywidgets and/or ipylab
- expose most of the current state of the current deck in a bidirectional manner
- active_index
- possible_directions
- slide_type
- active_widget
  - might be tricky to know the available main area widgets
- styles
- scroll_position (if relevant)
  - especially interesting for scroll-based effects, such as

on the typescript side
- hook into the DeckManager

This will be complicated by RTC, which still doesn't have a good story for widget state
