Remarks
Before executing the function that is declared to be the implementation of a command, the BeforeExecute event occurs. Any number of listeners may be registered for the event. Each listener executes when the event occurs.
If a listener claims it has implemented the command, no other listener or function should try to implement the command. A listener claims to have implemented the command by returning true for the handled parameter. If a listener only performs some extra function that was not supposed to be performed, such as making a log entry that the command fired or perhaps incrementing a counter displayed somewhere, then the listener returns false for the handled parameter.
Use CommandEvents.BeforeExecute.
