How to Add Custom Tooltip for Shapes in the Palette of Vue Diagram?

This article explains how to add a custom tooltip for shapes in the palette of the Vue Diagram. A tooltip is a text element that appears when a user hovers over an item, providing contextual information. In the Vue Diagram, tooltips can be shown on any diagram element such as nodes, connectors, or other components, making it easy to convey additional information. Tooltips are also available in the SymbolPalette, where they appear when the mouse hovers over any symbol.

To set a custom description for tooltips in the SymbolPalette, use the node’s tooltip property. This allows you to display custom content instead of the default node ID. Set the desired text in the tooltip’s content property to customize the tooltip for each symbol. Ensure that tooltip constraints are enabled in NodeConstraints for custom tooltips to appear.

The following code example demonstrates how to set a custom tooltip for symbols in the SymbolPalette:

let basicShapes = [
 { id: "Rectangle", shape: { type: "Basic", shape: "Rectangle" },
 tooltip:{
   content: 'Customized Tooltip',
 },
 // Enable customized tooltip to display on the symbol
 constraints: NodeConstraints.Default | NodeConstraints.Tooltip },
 { id: "Ellipse", shape: { type: "Basic", shape: "Ellipse" },
 tooltip:{
   content: 'Customized Tooltip',
 },
 // Enable customized tooltip to display on the symbol
 constraints: NodeConstraints.Default | NodeConstraints.Tooltip },
];

palettes: [
       {
         id: "flow",
         iconCss: 'e-ddb-icons e-flow', 
         expanded: true,
         symbols: flowShapes,
         title: "Flow Shapes"
       },
       {
         id: "basic",
         iconCss: 'e-ddb-icons e-basic',
         expanded: true,
         symbols: basicShapes,
         title: "Basic Shapes"
       },
     ],
