Add documentation for methods or helpers that are specific to qtpy

Beyond just letting people know to import Signal and Slot from here, are there QtPy-specific syntax or semantics that need to be described, or something else we want to say?

Besides the things described at the OP probably some description for the env variables that QtPy uses (FORCE_QT_API, QT_API) as well as state variables available (PYQT5, PYQT6, PYSIDE2, PYSIDE6, etc) could be nice (also letting clear that we are trying to follow Qt5 layout for things, so for example pyqtSlot -> Slot)

I assume this is related to Get rid of getexistingdirectory and patch QFileDialog? #26 ? Basically, we'd need basic documentation for these QtPy-specific helper functions? Since I'm not familiar with them, beyond just elaborating on the API and anything else the docstrings I'd need some help here with what to say.

Yes, related in the sense that following what is decided there (keeping it as it is, adding aliases to those functions or patching QFileDialog) the documentation should reflect that

That could be done directly in the readme because it's quite important.

[goanpeca]

Agreed!

Ok I will add this to the Readme now based on #76.

@Nodd, we never claimed to be 5.3 or something compatible, I think the aim was to be 5.6+, thoughts?

@dalthviz I can try to help with this, but given I'm not a Qt expert (both a benefit and a downside when writing user docs), I'll need a little more detail on what you want said here:

• Beyond just letting people know to import Signal and Slot from here, are there QtPy-specific syntax or semantics that need to be described, or something else we want to say?
• I assume this is related to #26 ? Basically, we'd need basic documentation for these QtPy-specific helper functions? Since I'm not familiar with them, beyond just elaborating on the API and anything else the docstrings I'd need some help here with what to say.
• This seems pretty streightforward
