@ohos.multimodalInput.shortKey (Shortcut Key)
The shortKey module provides APIs to set the delay for starting an ability using a shortcut key. For example, you can set the delay to 3 seconds so that a screenshot is taken when you press and hold the shortcut key for 3 seconds.
NOTE
The initial APIs of this module are supported since API version 10. Newly added APIs will be marked with a superscript to indicate their earliest API version.
The APIs provided by this module are system APIs.
Modules to Import
import shortKey from '@ohos.multimodalInput.shortKey';
shortKey.setKeyDownDuration
setKeyDownDuration(businessKey: string, delay: number, callback: AsyncCallback<void>): void
Sets the delay for starting an ability using shortcut keys. This API uses an asynchronous callback to return the result.
System capability: SystemCapability.MultimodalInput.Input.ShortKey
Parameters
Name | Type | Mandatory | Description |
---|---|---|---|
businessKey | string | Yes | Unique service ID registered on the multimodal side. It corresponds to businessId in the ability_launch_config.json file. |
delay | number | Yes | Delay for starting an ability using shortcut keys, in milliseconds. This field is invalid only when shortcut keys are used. |
callback | AsyncCallback<void> | Yes | Callback used to return the result. If the operation is successful, err is undefined. Otherwise, err is an error object. |
Example
try {
shortKey.setKeyDownDuration("screenshot", 500, (error) => {
if (error) {
console.log(`Set key down duration failed, error: ${JSON.stringify(error, [`code`, `message`])}`);
return;
}
console.log(`Set key down duration success`);
});
} catch (error) {
console.log(`Set key down duration failed, error: ${JSON.stringify(error, [`code`, `message`])}`);
}
shortKey.setKeyDownDuration
setKeyDownDuration(businessKey: string, delay: number): Promise<void>
Sets the delay for starting an ability using shortcut keys. This API uses a promise to return the result.
System capability: SystemCapability.MultimodalInput.Input.ShortKey
Parameters
Name | Type | Mandatory | Description |
---|---|---|---|
businessKey | string | Yes | Unique service ID registered on the multimodal side. It corresponds to businessId in the ability_launch_config.json file. |
delay | number | Yes | Delay for starting an ability using shortcut keys, in milliseconds. This field is invalid only when shortcut keys are used. |
Return value
Parameters | Description |
---|---|
Promise<void> | Promise that returns no value. |
Example
try {
shortKey.setKeyDownDuration("screenshot", 500).then(() => {
console.log(`Set key down duration success`);
});
} catch (error) {
console.log(`Set key down duration failed, error: ${JSON.stringify(error, [`code`, `message`])}`);
