RemarksThe state comprises of a Visibility and a tooltip. The visibility indicates whether the Operation should be visible at all, and if so whether it should be enabled. The tooltip can give a summary of the Operation when it's enabled, or an explanation of why it is disabled.
An OperationPresence is used for the return value from the [operation name]Presence methods generated for all defined Operations. The Persistate infrastructure calls these methods to determine whether user interface items such as menu items or toolbar buttons should be enabled and/or visible at a particular point in time.
