Hi,
Is there a way to extract the coordinates of the boxes that are defined by BoxEditTool?
What is the event that is being generated by adding the box to the renderer?

Alternatively, there was once a way to extract the coordinates of selection box by using something like this:
p.tool_events.on_change("geometries", toolEventsCallback)

This method have been deprecated in bokeh 0.12.14. I was wondering what is the current equivalent.
Thanks so much for the help,
Ilya

Thanks Bryan,
My question was not clear. I was trying to trigger a callback on the python side (on the server). As far as I understand the JS callbacks that you are mentioning are running in the browser, right?

Thanks again!

Hi,

The same events can trigger python callbacks in apps, see

  https://github.com/bokeh/bokeh/blob/master/examples/howto/events_app.py

Thanks,
