Overview of ArkTs Widget Page Editing Interaction

The home screen provides a unified widget editing page. The widget provider uses the startSecondPage method provided by FormEditExtensionContext of the FormEditExtensionAbility component to transfer the level-2 editing page information to the home screen. After the home screen opens the level-2 editing page, the page content can be edited.

The following figure shows the widget editing process.

FormEditExtensionAbility

When a user taps a widget to edit it, the widget provider inherits FormEditExtensionAbility to implement the widget editing function.
After the user identifies that the widget provider inherits FormEditExtensionAbility, the level-1 editing page of the widget provider is displayed.
The widget provider invokes the startSecondPage method of FormEditExtensionContext in the callback method onSessionCreate of FormEditExtensionAbility to transfer the level-2 page information of the widget provider to be started to the widget management service.
The widget management service transfers the received level-2 page information of the widget provider to the user.
Then the user opens the level-2 page to edit the page content.
