[Gnash-dev] Question about event handler types

What is a built-in event handler?  (comments in Sprite_instance.cpp,
::on_event(), line1951)

As far as I know,  we have (1)onClipEvent handler, which is defined in
the placement tags; and (2)user defined event handler, which is
defined by ActionScripts.

But what is a built-in event handler?   handlers like Key.onKeyUp()
and Key.onMouseUp()?  I think they are just user defined event
handlers.  They don't do anything if you don't define a function body
in ActionScripts.

listener =  new Object();
listener.onMouseDown = function () { .. }; //define the MouseDown event handler

Currently, Gnash ignores user defined  "onLoad", "onEnterFrame"(and
maybe other) event handler, and onClipKeyDown, onClipKeyUp(and maybe
others). That's odd...
