Hi Mike!

Its great to see you here.. :) I hope everything is great...

I am not sure if it helps at all, but some people have done work on using QT with cinder.
I guess that it should be possible to use QT for the GUI, event system etc and cinder just for the drawing.
Or maybe you could forward all events that take place within the QGLWidget to cinder for handling.

Here is a project ( that looks a bit old ) but appears to be combining the two:

You can also search in the forums since a few people appear to have done some work on it in the past.

Another option would probably be to use a scenegraph such as the one of Paul Houx:

or the one of Jeff LeBlanc ( ITP'07 )

https://forum.libcinder.org/topic/scene-graph-system

In this case, you would have to roll your own "gui widgets" on top of the scene graph..
