Deactivating hover tool in python callback

Is there a way to access the active attribute of a hovertool from a python callback? Just like what that JS callback does:

Tool.active is an internal property (to bokehjs), so no. However, I’m not sure exactly why it is this way. I don’t see any reason for not allowing users to configure active tools programmatically. Perhaps this has something to do with initialization of toolbars, which is pretty complicated. Maybe Bryan will have some more concrete feedback. Otherwise this seems something that could be improved.

from bokeh.models import CustomJS, Button
from bokeh.plotting import figure
from bokeh.layouts import gridplot
from bokeh.io import show

fig = figure(tools=‘hover’)

hover = fig.toolbar.tools[0]

button = Button(label=‘HoverOnOff’,width=150)

button.callback = CustomJS(args={‘hover’:hover},code=“hover.active = !hover.active;”)

x = range(10)
fig.scatter(x,x)

grid = gridplot([[button,fig]])

show(grid)
