You should really be using the dom specs or documentation on 
developer.mozilla.org for these kinds of things. It looks like you're 
just searching the source code. That may be useful to further 
understanding but it leads to finding all kinds of internal functions 
and classes that either shouldn't or can't be used from outside. In 
general any object that begins 'ns' without the 'nsI' isn't publicly 
useful.

Everything you need to know to send and receive events (from Javascript 
or C++) is documented in lots of places.
