    Hi I’m trying to make a little dialogue editor for my game.

    Just wondering if there’s an event I can tap into when you have released a ghost edge after dragging it out from a node’s port.

    I would like to be able to create a node simply by dragging out a edge from a port onto an empty part of the graph, maybe have a menu pop up to be able to create different node types etc. Right now I’m just using a button, which is a bit slow and I can only make it appear at a single location on the graph.

    Cheers

    Have you tried adding a callback to the GraphView instance 
    nodeCreationRequest
    callback? This should be called even when dragging an edge into an empty space.

    Just tried it... doesn't seem to do anything:

    
activeConversation = new ConversationGraphView
    
{
    
  name = conversationName,
    
};
    
activeConversation.nodeCreationRequest = x =>
    
{ Debug.Log($"Node creation request> index: {x.index}, mpos: {x.screenMousePosition}, target: {x.target}"); };

    Nothing prints or happens when I drag out and edge from a port or create a port conventionally with the button... o_O
