IPCB_PrimitivePolyline.setState_Polygon() method

This API is provided as a beta preview for developers and may change based on feedback that we receive. Do not use this API in a production environment.

Set the property state: single polygon

Signature

function setState_Polygon(polygon: IPCB_Polygon): IPCB_PrimitivePolyline;

Parameters

Parameter	Type	Description
polygon	IPCB_Polygon	Single polygon

Returns

IPCB_PrimitivePolyline

Polyline primitive object

Example

// 1. 生成本次运行专用的坐标，避免与之前保留的测试图元重合
const x = 2000 + Math.floor(Math.random() * 100000);
const y = 2000 + Math.floor(Math.random() * 100000);

// 2. 创建一条 500 → 拐弯 → 300 的折线
const polygon = eda.pcb_MathPolygon.createPolygon([x, y, 'L', x + 500, y, x + 500, y + 300]);
const polyline = await eda.pcb_PrimitivePolyline.create('', 1, polygon, 10, false);
const before = JSON.stringify(polyline.getState_Polygon().getSource());

// 3. 构造新轮廓（拉长到 800 → 拐弯 → 600），异步模式提交
const newPolygon = eda.pcb_MathPolygon.createPolygon([x, y, 'L', x + 800, y, x + 800, y + 600]);
const asyncPolyline = polyline.toAsync();
asyncPolyline.setState_Polygon(newPolygon);
await asyncPolyline.done();

// 4. 从画布重新读取，确认轮廓已替换（保留现场供观察）
const refetched = await eda.pcb_PrimitivePolyline.get(polyline.getState_PrimitiveId());
const after = JSON.stringify(refetched.getState_Polygon().getSource());

console.log('polygonSource:', before, '→', after);
