A Node Editor in QT specifically designed for Rendering Pipelines
After trying a couple of node editors I quickly came to the conclusion that they did not support my use-cases and the easiest way out was to develop my own. I am sharing this because maybe other people will find this useful.

Node Editor in QT
Be wary! The example is currently broken but since no-one uses this I'm not going to fix it since it now depends heavily on my external project. If you want to use this library and really want a working example raise an issue.
Problems currently: a lot of boilerplate needs to be written for a simple node editor to work, there's a lot of unoptimized stuff, and the rendering part itself needs a lot of love (text rendering outside of nodes)
However, this editor has support for
- dynamic input output ports, there are API calls that allow you to tell the framework that the ports of a specific node have changed. The downside is that all current connections will be destroyed since it's a pain to manage all that.
- custom widgets embedded into the node
This editor does not have support for
- automatic propagation, it requires you to recursively travel the node graph yourself, you can access the low level graph from the widget API. This was not one of my use-cases so it hasn't been planned, let me know if you need it, otherwise use this one: https://github.com/paceholder/nodeeditor/
