GraphEdit Improvements

[Eclextic]

As I feel that GraphEdit and GraphNode are pretty restrictive in their customizability I opened a discussion about it...

Necessary Features:

• Allow disabling GraphNodes default ports behavior (Add a port for every child using the child's position) and add a virtual/public method to control where to put a port and how many to put (Add new type called Port and fill an array with them with position/height as a variable of said Port type => Port().height = 10.0)

• Allow to manually control Input

  • By either giving an option to disable Input handling and making public functions or using the existing variables to modify the parameters (Move, Zoom, Select) or
  • By having exported InputActions (File) that can be replaced with the desired Input.

Necessary QoL:

• Have a list of neighboring connections of a GraphNode

  • (Graphnode1 <------ ConnectionGraphnode -----> GraphNode2)
  • Left: GraphNode1
  • Right: GraphNode2
  • If possible also remove the connection list from the GraphEdit as it is extremely unnecessary and is a performance issue. (Extra memory usage)

• Move a lot of the processing from the GraphEdit to the GraphNode (Connection/DisconnectionRequest, DeleteNodesRequest.

QoL:

• Add acceleration to the zoom as well as zoom mouse scroll delta.
• Line from and to icons so that you can make e.g. arrows going to the GraphNode.
• Line gradient coloring.

Feel free to suggest more features/ideas and I'll add them to the list!

I'm currently making a project management tool including task dependencies and using GraphEdit is a godsent, I just wish there were a few more tools available for it.

I'd like to be able to add nodes other than GraphNodes and have them treated in a similar way OR I'd like to be able to completely disable a graph node from being interacted with by the user. I thought the new "Dragable" and "Selectable" options from beta 2 would do the trick but apparently you can still click them and it pushes the nodes back to the top of the drawing stack.

Basically I want to be able to draw lines and boxes in the space of the GraphEdit, something like this:

where the post-its would be graphNodes, with all the current possibilities, and the lines and labels would be behind them all.

That’s cool but isn’t a GraphEdit.
What you can do is create a scene where there is a panel and a label node. Then through script change the different StyleBoxes used as well as handling the mouse input.

Also LineRenderer is also in Godot which might help you.

BUT if you need zoom, selection, card titles then even though GraphEdit is not intended for this use case you should probably use it

Well mostly I need the ability to link the cards together and navigate the panel, which are the two most important features of GraphEdit. But I'll figure something out 👍
