View-only mode?

Hi folks, thanks for the great tool!

I’m trying to wrap react-diagrams into a react component that would take some list of nodes and links between them and (maybe) auto-position them. The thing is DiagramWidget is stateful and events are emitted just to notify on the change. Is there (planned?) a way to disable some user interactions like removing the node or a link?

The only way to do it that I see now is to just re-create the engine, model, etc. and re-render the new DiagramWidget.

I implemented this at a core level now on all models.

You can lock any models by calling setLocked(true). It also uses a hierarchal system (see below)

• DiagramModel -> nothing can be changed
• LinkModel -> cannot move/delete/translate link, or add/remove/move/delete points
• NodeModel -> cannot move/delete/translate NodeModel
• PointModel -> cannot move/delete/translate this specific point

In addition, you can lock the canvas translations and zooming using new properties on the DiagramWidget
