jupyter widgets seem to be one-way. What if an attribute is changed elsewhere? Can it be dynamically change in the widget?

So basically you are saying, update the value in other part of the code, and then update the ui right?
I think it can be done by accesing the .value of the widget[1]. But I am not sure what you are trying, do you have a simple code to look at?

dynamic widget update can be problem because of recursion.

• set() methods change the class attributes
• new update() methods update widget values, but this must be called explicitly after using set() to change.

yes, change the widget.value in the .update() methods. This is a good enough solution. The user just needs to know and remember to use it when changing the values outside of the ui.
