接入手写交互

接入手写交互功能，对于需要接入支持双击/轻捏功能的手写笔的第三方应用，可以通过调用下面相应接口来监听手写笔双击/轻捏事件，从而触发自身应用内部回调，来执行指定操作。

接口说明

类名	接口名	说明
stylusInteraction	on(type: 'squeeze', receiver: Callback<SqueezeEvent>): void	监听手写笔轻捏事件。
stylusInteraction	off(type: 'squeeze', receiver?: Callback<SqueezeEvent>): void	取消监听手写笔轻捏事件。
stylusInteraction	on(type: 'doubleTap', receiver: Callback<DoubleTapEvent>): void	监听手写笔双击事件。
stylusInteraction	off(type: 'doubleTap', receiver?: Callback<DoubleTapEvent>): void	取消监听手写笔双击事件。

手写笔轻捏事件

1. 导入相关模块。

   import { stylusInteraction } from '@kit.Penkit';
   import { BusinessError } from '@kit.BasicServicesKit';

2. 监听手写笔轻捏事件。

   try {
     stylusInteraction.on('squeeze', (event: stylusInteraction.SqueezeEvent) => {
       console.info(`got squeeze event, time: ${event.timestamp}`);
     });
   } catch (err) {
     console.error('errCode: ' + (err as BusinessError).code + ', errMessage: ' + (err as BusinessError).message);
   }

3. 取消监听手写笔轻捏事件。

   try {
     stylusInteraction.off('squeeze', (event: stylusInteraction.SqueezeEvent) => {
       console.info(`off squeeze event, time: ${event.timestamp}`);
     });
   } catch (err) {
     console.error('errCode: ' + (err as BusinessError).code + ', errMessage: ' + (err as BusinessError).message);
   }

手写笔双击事件

1.导入相关模块。

import { stylusInteraction } from '@kit.Penkit';
import { BusinessError } from '@kit.BasicServicesKit';

2.监听手写笔双击事件。

try {
  stylusInteraction.on('doubleTap', (event: stylusInteraction.DoubleTapEvent) => {
    console.info(`got doubleTap event, time: ${event.timestamp}`);
  });
} catch (err) {
  console.error('errCode: ' + (err as BusinessError).code + ', errMessage: ' + (err as BusinessError).message);
}

3.取消监听手写笔双击事件。

try {
  stylusInteraction.off('doubleTap', (event: stylusInteraction.DoubleTapEvent) => {
    console.info(`off doubleTap event, time: ${event.timestamp}`);
  });
} catch (err) {
  console.error('errCode: ' + (err as BusinessError).code + ', errMessage: ' + (err as BusinessError).message);
}
