How to Change the Connector Segment Thumb Visibility in React Diagram?

In the Syncfusion® React Diagram, you have the ability to customize the behavior of connectors using the ConnectorConstraints.

By default, segments are rendered with a circular shape. If you need to modify the visibility of the segment thumbs in connectors, you can utilize the DragSegmentThumb constraint. This provides greater control over the user interaction with connector segments.

To effectively implement these constraints, ensure that you import and inject the ConnectorEditing module into your diagram configuration.

//Connector Editing module
Diagram.Inject(ConnectorEditing);

//DragSegmentThumb constraint
constraints: ConnectorConstraints.Default | ConnectorConstraints.DragSegmentThumb,

Below is a code example demonstrating how to change the visibility of the segment thumb based on toggle change

//Change the connector segment thumb visibility based on the toggleChange
 const toggleChange = () => {
   let selectedConnector =
     diagramInstance.selectedItems.connectors.length > 0
       ? diagramInstance.selectedItems.connectors[0]
       : diagramInstance.connectors[0];
   if (toggleInstance.checked) {
     selectedConnector.constraints =
       ConnectorConstraints.Default | ConnectorConstraints.DragSegmentThumb;
     diagramInstance.dataBind();
   } else {
     selectedConnector.constraints =
       ConnectorConstraints.Default & ConnectorConstraints.DragSegmentThumb;
     diagramInstance.dataBind();
   }
 };
