[Signals] Validation message

[starkimax]

Hey guys !

Thank you for this amazing project !
I had a question, is there any way I can update the graphic of the validation message without moving the node or creating a new connecting to this node ?

I'm asking this because I have nodes that can be updated without any new connection, they are updated when I edit my node widget.

It would be great if you could create a signal that would call your "drawValidationRect" function !
If your ok with it I can try to implement it on master branch.

Thx in advance ! Great job

Actually, I wanted to remove this graphical message because it looks ugly.
The better way to emphasize an input error would be possibly to highlight the input point with red..

Highlighting the missing input would be nice for sure, but I find the validation message can be still useful though. Or at least a generic runtime message :D

Well, the graphical message is maybe ugly, but I in my case It's very usefull to help the user know what he did wrong. I'll try to highlight the input as red, thx.
In my opinion, removing this graphical message would be a bad idea, it would remove possibilities for the user.

I would like to revisit this discussion. Considering @paceholder opinion on the graphical message being ugly, I implemented a tooltip behavior in PR #475 with a color scheme.

In my opinion, the color feedback should concern the entire node body, rather than the connection or port. I believe that an invalid state is a reflection of a combination of inputs and node configuration. An input is never wrong by itself. For the calculator example, dividing by 0 produces an invalid state. But the number 0 is not problematic itself.

In some applications, the invalid state occurs because the two inputs are not valid in relation to each other, rather than a single input being the cause of the error.
