Question regarding datoviz, backends, gtk about vispy HOT 5 CLOSED

Regarding the issues, I am yet to attempt calling /vispy/ext/egl as the _qt backend does
I am also yet to see if any existing offscreen backends like the ipython one work on wayland

from vispy.

I ask about vispy 2.0 as this could circumvent compatability issues, and also could make any work in 1.0 redundant

from vispy.

@rossant is the one who should answer about datoviz and "VisPy 2.0". As far as I know there is no direct work on a vispy -> datoviz compatiblity layer but rather a higher level and more generic protocol for defining visualizations. Any use of it in a operational/user workflow is likely not going to be ready in the near term. I also have zero experience with Wayland compatibility. Sorry.

Datoviz is based on Vulkan which does not appear to be supported by GTK (https://discourse.gnome.org/t/how-to-use-vulkan-context-in-gtk4/14997/2).

Also, Datoviz only supports glfw for now. Implementing PyQt support is high priority.

VisPy 2.0 is a medium-term project aiming at rebuilding high-level visualization capabilities on top of Datoviz and other renderers (including possibly VisPy 1.0) via a shared intermediate-level protocol.

So the answer is that unfortunately neither Datoviz nor VisPy 2.0 will allow you to work with GTK, at least not in an easy way.

@djhoese @rossant Thank you both for your clarification.
