API Frame RegisterEvent

Registers a frame to monitor for events. success = frame:RegisterEvent(event)

Arguments

 * event : - The name of the event to register the object as monitoring.

Returns

 * success : - True when frame is successfully registered to a new event; otherwise false, such as if the frame was already registered to this event.

Details

 * Widgets are usually notified of an event in order they were registered, but tends to move the last-registered widget up to fill the gap.  Consequently, this behaviour should not be relied upon.
