IPCB_PrimitiveFill.toAsync() method
将图元转换为异步图元
签名
typescript
function toAsync(): IPCB_PrimitiveFill;1
返回值
填充图元对象
示例
javascript
// 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. 创建一个无网络的矩形填充
const polygon = eda.pcb_MathPolygon.createPolygon(['R', x, y, 500, 300, 0, 0]);
const fill = await eda.pcb_PrimitiveFill.create(1, polygon, '', 0, 10, false);
// 3. 切换异步模式后批量修改:划归网络 + 挪到底层
const asyncFill = fill.toAsync();
asyncFill.setState_Net('嘉立创示例_NET');
asyncFill.setState_Layer(2);
await asyncFill.done();
// 4. 从画布重新读取,确认批量修改已生效(保留现场供观察)
const refetched = await eda.pcb_PrimitiveFill.get(fill.getState_PrimitiveId());
console.log('net:', JSON.stringify(refetched.getState_Net()));
console.log('layer:', refetched.getState_Layer());1
