@dylanvorster @renato-bohler If either of you have some consulting hours available wondering if you're available and interested in adding an enhanced change-detection feature to the latest version, if possible. Pinging @renato-bohler because you tried to explain to me what to do but I'm just too slow (projectstorm/react-diagrams#819) and @dylanvorster because well gosh you made this awesome thing.

Hi Guys, Does anyone know how to update the position of ports after dynamically adding/removing ports to a node? I saw some mention of calling the recalculatePortsVisually method on the DiagramEngine but I cannot find any such method. I have also tried calling port.reportPosition() but does not seem to update the ports position either. I am using v6.6.1 of the library.

Try to run simple example and get:

Uncaught TypeError: a.default is not a constructor
    at l.componentDidMount (index.umd.js:16:687)
    at commitLifeCycles (react-dom.development.js:20664:24)
...

Any ideas?

Hey all, does anyone know how to change the node draggable area? At the moment the whole node is draggable which is causing an issue if you want to highlight text on it. Ideally we'd disable the drag event when you're selecting text on the node, or set the drag event to a specific part of the node (e.g. a toolbar). Has anyone tried something similar?

I am trying to use the projectstorm react diagram library, so far I have managed to get something working in a demo project. But this I now want to use in my actual work project where they build react widget plugins, unfortunately I am a novice in react as well as typescript and my apologies if it is obvious that I know very little, I did the demo app by creating a react app in the usual way with npx create-react-app my-app, had to add some compiler options but all started working in the end. Then I trasnferred it to my work project but here I run into issues, it is a typescript react project and due to my limited knowledge I am not sure what is causing this issue, but the issue is that it is complaining about circular dependencies in the projectstorm diagram library. This is odd for me that it did not complain in the demo app but in this project which I created with a scaffolding tool provided to me for the IDE framework we are working in (a low-code framework), but to the eye the structure looks the same as my demo app, I installed projectstorm react digram in the same way. What in the coniler or setup will cause this circular dependency to be picked up as an error and how can I disable it? Obviously there is something setup differently but I do not know where to start looking. This is the 3 circular dependency errors:
Error: Circular dependency: node_modules/@projectstorm/geometry/dist/Polygon.js -> node_modules/@projectstorm/geometry/dist/Rectangle.js -> node_modules/@projectstorm/geometry/dist/Polygon.js
Error: Circular dependency: node_modules/@projectstorm /react-diagrams/node_modules/@projectstorm/react-diagrams-routing/dist/link/PathFindingLinkFactory.js -> node_modules/@projectstorm /react-diagrams/node_modules/@projectstorm/react-diagrams-routing/dist/link/PathFindingLinkModel.js -> node_modules/@projectstorm /react-diagrams/node_modules/@projectstorm/react-diagrams-routing/dist/link/PathFindingLinkFactory.js

Hi I am new to the tech stack sorry if this question is a little silly - I am wondering how we can store a modifiable value (say, an int) in a node and allow modification onDoubleClick, do we have to create customized nodes in order to do that? Thanks!

Hi, are there any issues in using useEffect with this project? I am fetching some data from a redux store (say nodes), observing changes to nodes using useEffect, and adding them to the diagram but this is not working for some reason. This is a pretty standard react flow. Is there anything I am missing here? Any help will be much appreciated

I have also raised an issue in github for the same projectstorm/react-diagrams#973

Also, I can see the nodes getting added to the model using model.getNodes() However, when I am calling repaint on the engine using engine.repaintCanvas() the new nodes are not showing up

asnaseer-resilient

@asnaseer-resilient

@abhisheksarka my guess would be that the new nodes that you are adding have a zero width and/or height

Yesterday, spent the whole day trying to figure out the issue. Same code triggered using on click is working. The problem is useSelector (not useEffect as I thought previously) is not playing nice with this library

Hello, when using RightAngleLinkModel the way it's used in storybook demos and setting model.setLocked(true), the links can still be moved around. What would be the recommended way to enable link locking with RightAngleLinkModel?
