@ohos.application.formProvider (formProvider)

The FormProvider module provides APIs related to the widget provider. You can use the APIs to update a widget, set the next refresh time for a widget, obtain widget information, and request a widget release.

NOTE The initial APIs of this module are supported since API version 8. Newly added APIs will be marked with a superscript to indicate their earliest API version. This module is deprecated since API version 9. You are advised to use formProvider instead.

Modules to Import

import formProvider from '@ohos.application.formProvider';

setFormNextRefreshTime

setFormNextRefreshTime(formId: string, minute: number, callback: AsyncCallback<void>): void

Example

import Base from '@ohos.base';

let formId: string = '12400633174999288';
formProvider.setFormNextRefreshTime(formId, 5, (error: Base.BusinessError) => {
  if (error.code) {
    console.error(`formProvider setFormNextRefreshTime, error: ${JSON.stringify(error)}`);
  }
});

setFormNextRefreshTime

setFormNextRefreshTime(formId: string, minute: number): Promise<void>

Name	Type	Mandatory	Description
formId	string	Yes	Widget ID.
minute	number	Yes	Refresh interval, in minutes. The value must be greater than or equal to 5.

Type	Description
Promise<void>	Promise that returns no value.

Example

import Base from '@ohos.base';

let formId: string = '12400633174999288';
formProvider.setFormNextRefreshTime(formId, 5).then(() => {
  console.log('formProvider setFormNextRefreshTime success');
}).catch((error: Base.BusinessError) => {
  console.error(`formProvider setFormNextRefreshTime, error: ${JSON.stringify(error)}`);
});

updateForm

updateForm(formId: string, formBindingData: formBindingData.FormBindingData,callback: AsyncCallback<void>): void

Updates a widget. This API uses an asynchronous callback to return the result.

System capability: SystemCapability.Ability.Form

callback	AsyncCallback<void>	Yes	Callback used to return the result.

Example

import Base from '@ohos.base';
import formBindingData from '@ohos.application.formBindingData';

let formId: string = '12400633174999288';
let param: Record<string, string> = {
  'temperature': '22c',
  'time': '22:00'
}
let obj: formBindingData.FormBindingData = formBindingData.createFormBindingData(param);
formProvider.updateForm(formId, obj, (error: Base.BusinessError) => {
  if (error.code) {
    console.error(`formProvider updateForm, error: ${JSON.stringify(error)}`);
  }
});

updateForm

updateForm(formId: string, formBindingData: formBindingData.FormBindingData): Promise<void>
