How to Change Font Color of Swimlane Header in Angular Diagram?

This article explains how to change the font color of a swimlane header in an Angular diagram. In Syncfusion, the Header is the primary element for swimlanes. The header property of the swimlane allows you to define its textual description and customize its appearance in the Angular Diagram.

To customize the font color of the swimlane header, you can use the color property within the style property within the swimlane header annotation. This allows greater flexibility in designing your diagrams.

Refer to the below code snippet for customization of font color in swimlane header:

header: {
         annotation: {
           content: 'SALES PROCESS FLOW CHART',
           //update font color for swimlane header
           style: { fill: 'black', color: 'yellow' },
         },
       }, 

The below code example shows how to customize the font color of swimlane header at run time using using color picker when the swimlane is selected:

//update font color for swimlane header at run time using color picker
 public fontColor(): void {
   if(this.diagram.selectedItems.nodes[0] && this.diagram.selectedItems.nodes[0].shape.type == "SwimLane")
   {
     let currentColor = (document.getElementById('fontColor') as HTMLSelectElement).value;
     (this.diagram.selectedItems.nodes[0].shape as ShapeModel | any).header.annotation.style.color = currentColor;
     this.diagram.dataBind();
   }
 }
 // Initializes the nodes for the diagram.
 public nodes: NodeModel[] = [
   {
     shape: {
       type: 'SwimLane',
       orientation: 'Horizontal',
       // customize the swimlane header
       header: {
         annotation: {
           content: 'SALES PROCESS FLOW CHART',
           //update font color for swimlane header
           style: { fill: 'black', color: 'yellow' },
         },
       },
       lanes: [
         {
           id: 'stackCanvas1',
           height: 100,
         },
       ],
       phases: [
         {
           id: 'phase1',
           offset: 170,
           header: { annotation: { content: 'Phase' } },
         },
       ],
       phaseSize: 20,
     },
     offsetX: 300,
     offsetY: 200,
     height: 200,
     width: 350,
   },
 ];
