Detailed Documentation

•V2 Full Guide: See references/v2-guide.md for complete V2 API, templates, events, and advanced features
•V1 Full Guide: See references/v1-guide.md for complete V1 API and patterns
•Migration Guide: See references/migration-v1-to-v2.md for converting V1 code to V2

Common Tasks

Adding Nodes Programmatically

V2:

javascript

family.addNode({ id: 4, mid: 1, fid: 2, name: "New Child", gender: "female" });

V1:

javascript

family.add({ id: 4, mid: 1, fid: 2, name: "New Child" });

Handling Events

V2:

javascript

family.onNodeClick((args) => {
    console.log("Clicked:", args.node);
});

V1:

javascript

family.on("click", function(sender, args) {
    console.log("Clicked:", args.node);
});

Exporting

V2:

javascript

family.exportPDF();
family.exportPNG();
family.exportSVG();

V1:

javascript

FamilyTree.pdfPrevUI.show(family, { format: "A4" });
FamilyTree.exportPNG(family, {});

Workflow

•New Project: Read references/v2-guide.md → implement with V2 API
•Existing V1 Project: Read references/v1-guide.md → maintain with V1 API
•Migration: Read references/migration-v1-to-v2.md → convert systematically
