3 years ago Just chiming in to say that this is probably the issue I just described in #56 as well (apologies for the duplication). Copying my comment over:
Hi, I think I am experiencing this issue even when I have the latest version of the npm / pypi packages installed.
I'm using jupyterlab 3, and have the latest ipyevents:
Environment
``` $ pip show ipyevents jupyterlab ipywidgets Name: ipyevents Version: 0.8.1 Summary: A custom widget for returning mouse and keyboard events to Python Home-page: https://github.com/mwcraig/ipyevents Author: Matt Craig Author-email: mattwcraig@gmail.com License: BSD 3-clause Location: /Users/jan/github/ipyannotations/.venv/lib/python3.8/site-packages Requires: ipywidgets Required-by: --- Name: jupyterlab Version: 3.0.3 Summary: The JupyterLab server extension.

They seem to be installed, although there's something different about ipyevents:
$ jupyter labextension list
JupyterLab v3.0.3
/Users/jan/github/ipyannotations/.venv/share/jupyter/labextensions
ipycanvas v0.8.1 enabled OK
ipyannotations v0.1.0 enabled OK
@jupyter-widgets/jupyterlab-manager v3.0.0 enabled OK (python, jupyterlab_widgets)
Other labextensions (built into JupyterLab)
app dir: /Users/jan/github/ipyannotations/.venv/share/jupyter/lab
ipyevents v1.8.1 enabled OKThe following error occurs in the javascript console when trying to run an example:
from ipywidgets import Label, HTML, HBox, Image, VBox, Box, HBox
from ipyevents import Event

l.layout.border = '2px solid red'
h = HTML('Event info')
d = Event(source=l, watched_events=['click', 'keydown', 'mouseenter'])
def handle_event(event):
lines = ['{}: {}'.format(k, v) for k, v in event.items()]
content = '<br>'.join(lines)
h.value = content
d.on_dom_event(handle_event)

As per this Jupyter Discourse thread, I have been running into some funky issues with
ipyeventson JupyterLab 3.I don't feel that I understand this well at all, but I think what might be going on is simply that this project's
package.jsonneeds to be updated to indicate that it is also compatible with the 4.x series of@jupyter-widgets/base. @mwcraig if you agree with this diagnosis I'm happy to prepare a PR, but I wanted to post an issue first since you're a lot more familiar with this stuff than I am.CC @matthewturk who expressed interest in this topic on Twitter.
