@ohos.multimodalInput.pointer (Mouse Pointer) (System API)

The pointer module provides APIs related to pointer attribute management.

NOTE

The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.

This topic describes only system APIs provided by the module. For details about its public APIs, see @ohos.multimodalInput.pointer (Mouse Pointer).
