You can check this example
that implements eventFilter
(see googlesuggest.py)

Yeah, indeed that's one of the wrongly translated snippets,
because the process is automated. Could you please open a bug report to 
fix it?

These documentation glitches make me think I'm missing some other resources that are more specifically about PySide6.  Any advice?

You are not missing out other material,
personally, I always recommend people to check the 'examples'
for learning purposes.

The reason of having those mistranslated snippets
is because before, that was a manual process,
and due to the amount of snippets in Qt,
it was never even 20% done. So the team decided
to automatically translate the snippets,
which can provide more context, but with a price
of having some of them wrongly translated.
For that, we require feedback (like the one you gave!)
of which are the snippets that require a fix.

Regarding that page,
you can find the C++ code as well:

Once you file the bug report, we can do a manual
translation and provide the proper code snippets in
