How to Remove Tooltip From Nodes and Connectors in Vue Diagram?

This article explains how to remove tooltips from nodes and connectors in Vue Diagram. In our Graphical User Interface (GUI), a tooltip appears when you hover your mouse over an element. This message provides additional information to enhance your experience and understanding of the interface.

If you prefer not to see these tooltips, you can easily remove them by disabling the tooltip constraints for nodes or connectors, respectively, in Vue Diagram.

Below is a code example demonstrating how to disable the tooltip for nodes/connectors:

<template>
   <div id="app">
       <ejs-diagram id="diagram" :width='width' :height='height' :getNodeDefaults='getNodeDefaults'
           :getConnectorDefaults='getConnectorDefaults' :layout='layout'
           :dataSourceSettings='dataSourceSettings'></ejs-diagram>
   </div>
</template>
<script>

import { DiagramComponent, HierarchicalTree, DataBinding,ConnectorConstraints,NodeConstraints } from '@syncfusion/ej2-vue-diagrams';
import { DataManager, Query } from "@syncfusion/ej2-data";

let data = [{
   Name: "Steve-Ceo"
},
{
   Name: "Kevin-Manager",
   ReportingPerson: "Steve-Ceo"
},
{
   Name: "Peter-Manager",
   ReportingPerson: "Steve-Ceo"
},
{
   Name: "John- Manager",
   ReportingPerson: "Peter-Manager"
},
{
   Name: "Mary-CSE ",
   ReportingPerson: "Peter-Manager"
},
{
   Name: "Jim-CSE ",
   ReportingPerson: "Kevin-Manager"
},
{
   Name: "Martin-CSE",
   ReportingPerson: "Kevin-Manager"
}];
let items = new DataManager(data, new Query().take(7));
export default {
   name: "App",
   components: {
       "ejs-diagram": DiagramComponent
   },
   data() {
       return {
           width: "100%",
           height: "350px",
           // Uses layout to auto-arrange nodes on the Diagram page
           layout: {
               // Sets layout type
               type: 'HierarchicalTree'
           },
           dataSourceSettings: {
               id: 'Name',
               parentId: 'ReportingPerson',
               dataManager: items
           },
           getNodeDefaults: (obj) => {
               obj.shape = {
                   type: 'Text',
                   content: obj.data.Name
               };
               obj.style = {
                   fill: 'None',
                   strokeColor: 'none',
                   strokeWidth: 2,
                   bold: true,
                   color: 'white'
               };
               obj.borderColor = 'white';
               obj.width = 100;
               obj.height = 40;
               obj.backgroundColor = '#6BA5D7';
               obj.borderWidth = 1;
               obj.shape.margin = {
                   left: 5,
                   right: 5,
                   top: 5,
                   bottom: 5
               };
                //define tooltip
                obj.tooltip = {
                 content : obj.data.Name
             }
             // Disable the tooltip for connector
             obj.constraints = NodeConstraints.Default & ~NodeConstraints.Tooltip;
               return obj;
           },
           getConnectorDefaults: (connector) => {
               connector.type = 'Orthogonal';
                // Define the tooltip for connector
                connector.tooltip = {
                 content : connector.id
               }
               // Disable the tooltip for connector
               connector.constraints = ConnectorConstraints.Default & ~ConnectorConstraints.Tooltip;
               return connector;
           },
       }
   },
   provide: {
       diagram: [DataBinding, HierarchicalTree]
   },
