Known Indirect Subclasses
Augments an event with support for cancelation.
When a cancelable event is raised, any listener may choose to cancel the operation. A descriptive message must be provided, explaining why the operation was canceled. If any listener cancels the operation, it will not be performed--even if other listeners did not cancel. In other words, if three listeners receive the event and only one of them cancels, the associated operation will be considered canceled.
