NSAccessibilityGroup
A role-based protocol that declares the minimum interface necessary to act as a container for other user interface elements.
Declaration
protocol NSAccessibilityGroup : NSAccessibilityElementProtocolOverview
Visual users often know that sets of controls go together due to their proximity on the screen. However, you must explicitly define these relationships before assistive apps can use them as well. Use this protocol when you want to logically group a collection of accessibility elements. A view that adopts this protocol indicates that an assistive app should treat its content as a group of controls.
You can further enhance the adopting element by implementing any of the information properties or action methods that the NSAccessibilityProtocol protocol declares.
