Static class methods are unable to access any members or methods that require a "self" parameter.  

As a result it can not be assigned to an event.

Alternatively one could create a plain procedure with the right signature, assign that to the code pointer of a TMethod record, leave the data pointer unassigned or set it to nil, and assign that record to the event using appropriate type casting.

That's the way I usually do it when I need an event handler without an object instance.
