How to Prevent Node Rotation in Vue Diagram?

This article explains how to prevent node rotation in Vue Diagram. In the Syncfusion® Vue Diagram, we have the flexibility to enable or disable specific behaviors of nodes through the use of NodeConstraints.

To prevent the rotation of a node in Diagram, we can use the Rotate NodeConstraint and disable it using the Bitwise ‘&~’ (XOR) operator.

// Set the constraints for node as Rotate and disable it
constraints: NodeConstraints.Default & ~NodeConstraints.Rotate

Below is a code example demonstrating how to prevent rotation in a node:

<template>
 <div class="col-lg-9 control-section">
   <!-- Diagram component section -->
   <div class="content-wrapper">
     <ejs-diagram
       id="diagram"
       ref="diagram"
       :width="width"
       :height="height"
       :nodes="nodes"
     ></ejs-diagram>
   </div>
 </div>
</template>

<script>
import {
 DiagramComponent,
 Diagram,
 NodeConstraints,
} from '@syncfusion/ej2-vue-diagrams';

let nodes = [
 {
   offsetX: 250,
   offsetY: 250,
   width: 100,
   height: 100,
   constraints: NodeConstraints.Default & ~NodeConstraints.Rotate,
 },
];

// Export Vue component
export default {
 components: {
   'ejs-diagram': DiagramComponent,
 },
 data: function () {
   return {
     width: '100%',
     height: '350px',
     nodes: nodes,
   };
 },
};
</script>
