ISCH_PrimitiveAttribute.setState_UnderLine() 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: whether it is underlined

Signature

function setState_UnderLine(underLine: boolean | null): ISCH_PrimitiveAttribute;

Parameters

Parameter	Type	Description
underLine	boolean | null	Whether it is underlined

Returns

ISCH_PrimitiveAttribute

Attribute 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器件重合
const x = 2000 + Math.floor(Math.random() * 6000);
const y = 2000 + Math.floor(Math.random() * 6000);

// 2. 放置测试器件并取出 Designator（编号）属性
const devices = await eda.lib_Device.search('C0402');
const comp = await eda.sch_PrimitiveComponent.create(devices[0], x, y);
const attrIds = await eda.sch_PrimitiveAttribute.getAllPrimitiveId(comp.getState_PrimitiveId());
const attrs = await eda.sch_PrimitiveAttribute.get(attrIds);
const designator = attrs.find(a => a.getState_Key() === 'Designator');

// 3. 切换异步模式加下划线并提交
const asyncAttr = designator.toAsync();
asyncAttr.setState_UnderLine(true);
await asyncAttr.done();

// 5. 从画布重新读取，确认修改已生效（保留现场供观察）
const refetched = await eda.sch_PrimitiveAttribute.get(designator.getState_PrimitiveId());

console.log('underLine:', refetched.getState_UnderLine());
