AbilityComponent
<AbilityComponent> is a container for independently displaying an ability.
NOTE
This component is deprecated since API version 10. You are advised to use <UIExtensionComponent> instead.
This component is supported since API version 9. Updates will be marked with a superscript to indicate their earliest API version.
The APIs provided by this component are system APIs.
Constraints
<AbilityComponent> is rendered independently and cannot be overlaid with other display content.
<AbilityComponent> cannot process input events. Events are directly distributed to the internal ability for processing without passing through the current ability.
Only width and height can be set for <AbilityComponent>. These attributes are mandatory and cannot be dynamically updated.
The ability to be started must inherit WindowExtension.
