    If you want to avoid licensing issues altogether, you might want to have a look at Dear PyGui. It's has a permissive MIT license. It's easy-to-use and fast (C++ and GPU-based). Admittedly, it doesn't offer Qt level features yet, but it offers fast graphs and tables, so it meets the basic requirements for data analysis. The core developers are very supportive and responsive.

    Latest mention: Teamspeak 5 to be based on the Matrix protocol | news.ycombinator.com | 2021-01-12

    Regarding Matrix+Mumble, here was my plea: https://github.com/mumble-voip/mumble/issues/1813#issuecomme...

    Currently, I am envisioning posting `mumble:` links in matrix channels, maybe pinning the message, together with a bit more info in custom events.

    If a Matrix client doesn't integrate mumble client functionality, you could still click on links. If it does, there could be some further integration with authentication.

  • ricochet

    Anonymous peer-to-peer instant messaging

    Latest mention: 'Use Signal. Learn about privacy coins. Insist on working remotely. Embrace open source. Practice online anonymity. Decentralize your life.' - naval | reddit.com/r/Monero | 2021-01-11

    Ricochet used to be my messenger of choice, but it is not actively maintained, so I don't trust it anymore. I also used OTR, but that is not maintained anymore either. I now have a lot of hope for Cwtch, which re-implements and expands many of the features that Ricochet has (and, arguably, improves, such as not depending on qt by writing an entire independent graphics suite). However Cwtch is not ready for wide usage yet, the ux and ui is still kinda clunky. I started using it, but it is not a daily driver yet. Their deveopment is pretty active though and you can support it by donating to https://openprivacy.ca/ .

  • wxWidgets

    I recommend you take a look at how Urho3D does it as a solid working example: Urho3D/blob/master/Source/Urho3D/Physics/CollisionShape.cpp#L282
