Invisible progress bars when using ipywidgets / tqdm progress bars

[ndalchau]

I always use ipywidgets to make tqdm progress bars look nicer in Jupyter notebooks:

Unfortunately, this does not render correctly when presenting in RiSE:

The progress bar is invisible, and the font sizes are too small.

Is RiSE compatible with ipywidgets?

Hi

We have examples of interactive demos in rise built on top of ipywidgets, so generally speaking I would tend to say yes

this being said, I was not aware of that library, so I have an empty mileage
as per the README though https://github.com/tqdm/tqdm#ipython-jupyter-integration,
it looks like you're supposed to import stuff through the tqdm.notebook module, right ?

have you tried that approach ?

Thanks for the response @parmentelat . I've tried using all of the various incarnations that I know about. I find that from tqdm.notebook import tqdm and from tqdm.auto_notebook import tqdm give the same behaviour as from tqdm.auto import tqdm, as above.

I'm pretty sure this has to do with the CSS class .progress being used by both tqdm and reveal.js, where the latter applies display: none when toggling the presentation mode. Not sure how to fix it but including this in my local CSS made the tqdm progress bars appear in presenter mode (but not when toggling back to regular view):

.widget-hprogress .progress {
  display: block !important;
}
