How to Disable Annotations on Connector in Angular Diagram?

In this article, you can learn how to disable annotations on connectors in an Angular Diagram. The Angular Diagram component supports editing annotations at runtime, either interactively or programmatically. However, to restrict users from adding or editing annotations, you can utilize the constraints property.

The constraints property allows you to control the behavior of annotations, such as making them read-only. To disable annotation editing or prevent new annotations from being added, apply the “read-only” constraint to the annotation. This ensures that the annotation cannot be modified or edited by double-clicking a connector.

Below is an example code snippet demonstrating how to apply the read-only constraint:

//Define connector with ReadOnly constraint
       public connectors: ConnectorModel[]=[
           {
               id: "connector1",
               sourceID: "Start",
               targetID: "Init",
               type: 'Orthogonal',
               //disable annotation editing
               constraints:
                 ConnectorConstraints.Default | ConnectorConstraints.ReadOnly,
           }
       ]
