 |
 |   Description:
 |      This file defines some macros that implement things common to
 |      many subclasses of SoEvent. They may be used to make SoEvent
 |      subclassing easier. In all of the macros, the "className"
 |      parameter refers to the name of the event subclass.
 |
 |   Defined macros:
 |
 |      Within class header:
 |
 |              SO_EVENT_HEADER(className)
 |
 |      Within class source:
 |
 |          At file scope:
 |
 |              SO_EVENT_SOURCE(className)
 |
 |          Class initialization (initClass):
 |
 |              SO_EVENT_INIT_CLASS()
 |
