Diagramming shouldn't be hard. I know. Me too.

Is there a built-in way to edit nodes (the name for example) or do I have to implement it manually?

If there is no way to do it out of the box, is there some example of how to extend a node to add for example an edit button or a button to add new port?

Hey @KKSzymanowski ,

To edit nodes, you've to implement it manually. Just put a edit and use the onChange event. For example:

onChange={(e) => {
                             // node receive value of edit
                              node_example.options.name = e.target.value;
                             // refresh diagram with new node name
                              engine.repaintCanvas();

                            }}

I'm using dagre to distribute the nodes in the diagram. I randomly place the nodes and "autodistribute" them:

import {
  DagreEngine,
  PathFindingLinkFactory,
} from '@projectstorm/react-diagrams';

import centerModel from '../Actions/centerModel';

const reroute = (engine) => {
  engine
    .getLinkFactories()
    .getFactory(PathFindingLinkFactory.NAME)
    .calculateRoutingMatrix();
};

const autoDistributeNetwork = (engine, useGraphOptions = true) => {
  const graphOptions = useGraphOptions
    ? {
        rankdir: 'TB',
        ranker: 'longest-path',
        marginx: 50, // margin of whole diagram
        marginy: 50, // margin of whole diagram
        nodesep: 200, // minimum x distance between nodes
        ranksep: 100, // minimum y distance between nodes
      }
    : {};

  const distributionEngine = new DagreEngine({ graph: graphOptions });

  distributionEngine.redistribute(engine.getModel());
  reroute(engine);
  centerModel(engine);
};

Additionally I have a sidebar which can pull in from the side and shrinking the canvas. On this action the nodes on the diagram "crumble" together in the state they used to have before "autodistribution" kicked in. And it keeps in this state. Calling autoDistributeNetwork has no effect on the layout. Even dragging and dropping has no (coordinated) effect (the nodes get picked randomly and dropped at weird places).

Does anyone encounter this problem as well? How can I get around this?

Hi All,

@AymenMarouani

Simple question, I'd like to ask about the property added to DiagramWidget called inverseZoom to inverse the behavior of the mouse's zoom wheel(see projectstorm/react-diagrams#95): actually, I'm using CanvasWidget which came after DiagramWidget with a react-diagrams version 6.5.2 as following `

<CanvasWidget  engine={engine}/>

Does any one have an example of how to add the property inverseZoom to work with (code please) ?
Thanks in advance.

So... when I add repaintDebounceMs to the engine options, it sometimes disables panning the CanvasWidget.

  const engine = createEngine({
    registerDefaultDeleteItemsAction: false,
    repaintDebounceMs: 50
  })

Anyone else seen this?

Aaron Michaux

@aaron-michaux

For anyone out there, the problem went away when I patched engine.repaintCanvas, so that debouncing happens on the leading edge of the timeout.

Hey fellow developers, does anyone know if there is a way to get the ids of the visible ports (i.e. not zoomed out or dragged out of view from canvas)?

Hey folks, I'm just getting started with react-diagrams. I'm following the demo project for custom node widget/model/factory. I've written a custom node model, extending NodeModel, and in overriding the deserialize function I'd like to provide the type for the event parameter - but auto imports aren't working for some reason. So, where can I import the DeserializeEvent from? And should I use it like this:

deserialize(event: DeserializeEvent<CustomNodeModel>) {...}

your problem is when trying to assign null the variable in your declaration, try:
var node: DefaultNodeModel;
I'm sure it will work for you!

Hello everyone!

I'm trying to get the diamond node model demo working, but it gives me an error using it as written when running it through create-react-app's npm start script

Error: Cannot find factory with type [diamond]

More specifically I'm trying to use this with the drag and drop demo, and I've got it showing up in the tray on the left hand side, but when I drag it on to the canvas I get the error

How do you let your app know how to find the factory for it?

K Wood

@kristopher-wood

Got it! Instead of defining engine as new CreateEngine, I needed to use this.props.app.getDiagramEngine()
