Interactive widgets not working anymore in recent Jupyter notebook

[delaere]

As commented already in #78, I observe an issue similar to #17, but here in a standard Jupyter notebook. The javascript error message also looks different.

While it was working perfectly a few months ago, I am now unable to use the drawingWidget in Jupyter. I guess that this is related to the update of python and/or Jupyter.
I now get the following error message:

Failed to create view for 'DrawingView' from module 'drawingview' with model 'DOMWidgetModel' from module '@jupyter-widgets/base'
TypeError: Class constructor O cannot be invoked without 'new'

I just confirmed the problem in a clean virtualenv following the recipe below and running the interactive widget demo.

virtualenv -p python3 debug-venv
source debug-venv/bin/activate
pip install drawSvg hyperbolic jupyter
pip freeze >packages.txt
jupyter notebook

I am running Python 3.10.8 on Fedora Linux 36. The issue appears both with the chrome-based Vivaldi browser 5.5.2805.44
and in Firefox 106.0.4 . The packages list is there: packages.txt

Thanks for your help!

Thanks for reporting this. I also see this issue. It looks like Jupyter notebook removed support for classic widgets.

I'll look into rewriting DrawingWidget for the new API.

Fixed and published version 1.9.0. Re-open this issue if it doesn't work.

The issue turned out to be related to JavaScript ES6 classes and unrelated to #17. The latest Jupyter notebook front-end no longer works with the old DOMWidgetView.extend(...) style. I had to update it to class DrawingView extends DOMWidgetView {...}.
