Is this different from using a notebook file?

[flideros]

I have a qwidget that starts and stops the jupyter lab process and displays the tree view and open notebook in an iframe in a QWebEngineView. Less than 70 lines of code and all the features of the notebook are available through the jupyter lab interface. How does the qtconsole make things better?

qtconsole is used as a widget inside Spyder and makes sense in that context. Whether it makes sense to use it in other contexts is completely up to you.

To expand on what @wmvanvliet said, Qtconsole is also used by other Qt-based applications (e.g. Napari) to provide a console-like interface to run code (i.e. a very similar behavior to what you get when running commands in a terminal).

So, you won't be able to build a narrative that includes text, equations, images and code. You can only use QtConsole to run code, but using the same backend architecture as JupyterLab.
