@paceholder, I'm pretty sure your example from UE4 is not what he is looking for. Imagine you have elaborated the calculator to have some quite complex math taking place, and...

Ah ok I see now I think you did understand, I just didn't understand your UE4 analogy. Just seems hacky, that's all. Seems strange that all nodes would need to...

They should be editable, like comments in code. Tooltips for what nodes do could be another feature too though...

Maybe there could be a virtual function in `NodeDataModel` that gives HTML for documentation on hover. That would definitely be useful

> I can embed a comment QLabel Would this be a description of the node type (set by `NodeDataModel`) or a comment for the user (set by the user)?

I'll take this one on, you can asign me (I don't think i have permissions to)

The way I'm thinking about implementing this is everything is normal, then when you hover over the node, some hint appears that you can enter a comment, something like this:...

As far as painting, I don't think it should be too much work, but I haven't done very much work with `QPainter` in the past, so I don't know. Seems...

It doesn't really make sense to have multiple input nodes for a data flow graph, so is not supported. However, #117 generalizes this library to be a generic node rendering...
