I was wondering if there is a possibilty to get all the callbacks related to a defined widget for test purposes.
Imagine the following:
input= widgets.Password( value="", placeholder="", description='Password:', disabled=False ) def on_change(change): # do something here input.observe(on_change, names='value')
I want to know how i can get a list/set/dictionary/… which tells me all the callback functions related to the widget input.
In this case for example
[on_change] or something like that.
I already tried out various things, I guess the closes was:
Nevertheless, this give me an empty list.
