ISCH_PrimitiveAttribute.getState_UnderLine() method

Get the property state: whether it is underlined

Signature

function getState_UnderLine(): boolean | null;

Returns

boolean | null

Whether it is underlined

Example

// 1. 放置一个测试器件（属性图元随器件生成，无法单独创建）
const devices = await eda.lib_Device.search('C0402');
const comp = await eda.sch_PrimitiveComponent.create(devices[0], 600, 600);
const compId = comp.getState_PrimitiveId();

// 2. 取出器件的属性图元，定位 Designator（编号）属性
const attrIds = await eda.sch_PrimitiveAttribute.getAllPrimitiveId(compId);
const attrs = await eda.sch_PrimitiveAttribute.get(attrIds);
const designator = attrs.find(a => a.getState_Key() === 'Designator');

// 3. 读取编号文本是否加下划线（null 表示跟随默认样式）
const underLine = designator.getState_UnderLine();

// 4. 清理测试器件（属性图元随器件一起删除）
await eda.sch_PrimitiveComponent.delete([compId]);

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