Anntation Constraint is not worked

[aim Systems]

hi

I want to prevent users from changing the Annotation in Connector arbitrarily. Although I checked the 'ReadOnly' property in AnnotationConstraint, it doesn't work. Is there any other way to prevent Annotation from being changed?

Hi,

We have created the sample for your requirement. If you want to give readOnly annotation constraints for all connectors in the diagram, you can set it in the getConnectorDefaults method. If you need to set constraints for the specified connector, you can define it in the connector itself. Please refer the sample below.

Code-snippet

getConnectorDefaults

 

 getConnectorDefaults: (obj) => {

  if( obj.annotations &&  obj.annotations.length>0)

{

  obj.annotations[0].constraints =  AnnotationConstraints.Default |AnnotationConstraints.ReadOnly

  }

},
