Add event when create, update, or create an annotation

[hoxbro]

resolves #76

I'm going back and forth between having one event for all or an event for each of the types.

Code

from __future__ import annotations

import holoviews as hv
import panel as pn

from holonote.annotate import Annotator, SQLiteDB
from holonote.app import PanelWidgets

hv.extension("bokeh")
pn.extension(notifications=True)

connector = SQLiteDB(table_name="test_events")

annotator = Annotator({"TIME": float}, fields=["description"], connector=connector)
anno = annotator * hv.Curve(range(10), kdims="TIME")


def notification(e):
    if e.type == "create":
        pn.state.notifications.info("Annotation created")
    elif e.type == "delete":
        pn.state.notifications.error("Annotation deleted")
    elif e.type == "update":
        pn.state.notifications.success("Annotation updated")


pn.bind(notification, annotator, watch=True) # or annotator.on_event(notification)


b = PanelWidgets(annotator)
pn.Row(b, anno).servable()
