[jowr]

As a follow up on #231, I have tried to move to qtpy. Are you att all interested in such a change?

Hi @jowr ,

Thanks for the pull 😃, I'm interested however it's not a priority for me at this time.

That's exactly the pull request I'm looking forward !
I need to integrate a node editor into a project written with qtpy that only works with PyQt6 or PySide6. I've had to use pyqtnodeeditor, which isn't really good to my project.
Why is this pull request not merged ?

I merged @jowr's qtpy branch with the changes made to this repo's main branch since their divergence. My own fork's main branch currently has the most recent changes from both repos' branches. I'm not a git wizard, but I did review and resolve each conflict manually. Please let me know if anything looks wrong.

For anyone looking to use PySide6/PyQt6 with this project, I would recommend checking out my fork. It looks like @jchanvfx may not be interested in officially adding PySide6 support for some time, if at all...
