REPO IS NO LONGER MAINTAINED AND DOES NOT SUPPORT JUPYTERLAB>=3.0.0

[pmarcellino]

I just spent quite a while setting up an environment and troubleshooting different issues, when I realized that this repo is no maintained and does not support any recent version of jupyterlab.

I recommend IPYDataGrid (https://github.com/bloomberg/ipydatagrid) as a working alternative to QGrid.

• It lacks documentation, but it does work with current versions of Python, Jupyter Lab, and IPYWidgets as of January 2023.

Nice UX, but much slower to load big dataframes :-(

There is a new QGrid "fork" (the same codebase just not git-cloned) that works with all latest jupyter machinery, minus ipywidgets-8+:

https://github.com/JohnOmernik/qgrid

It was packaged with all NPM dependencies in wheels, and works out of the box.

Is it just the initial loading that is slow for you? I fixed a bug on this recently that made initialising much faster.

I believe that QGrid loads dataframe lazily by default, it discovers the shape of rows/columns and when scrolling, it populates cells only when the mouse is at rest. Does ipydatagrid has lazy loading capabilities?

[vthemelis]

I assume that by "loads dataframes lazily" you mean that it doesn't add DOM elements for the rows/columns that are out of view?

If yes, ipydatagrid doesn't actually use the DOM elements to represent its structure but uses a canvas element on which of course it only draws the rows/columns that are currently in view.

Out of interest, what were the symptoms of slowness that you observed? Might be worth an issue on the ipydatagrid repo.

[ankostis]

I takes ~11sec to load 200k rows dataframe, while QGrid loads instantly (and ipyaggrid takes 7sec).

I've created a new repo QgridNext to continue maintaining Qgrid for future Jupyter versions.

QgridNext is now compatible with recent releases of Jupyter:

QgridNext	JupyterLab	Notebook	Voila
v2.0.0	v3 - v4	v5 - v7	v0.2 - v0.5

Now it works as a prebuilt extension (introduced in JupyterLab 3), hence JupyterLab 1/2 are no longer supported. I've reorganized documents, readme, test environments and demos for a fresh start for the new repo. Your feedback, issues and PRs are welcomed and highly appreciated!
