ok, I've got this event code (a modified quit handler)...

Code:

    EventTypeSpec    quitEvent[] = {kEventMouseDown};

    EventHandlerUPP    quitEventHandler;

    EventHandlerRef    quitEventHandlerRef;

...

quitEventHandler = NewEventHandlerUPP((EventHandlerProcPtr)do_QuitEventHandler);

InstallEventHandler(GetApplicationEventTarget, quitEventHandler, 1, quitEvent, NULL, quitEventHandlerRef);

which gives this error...
cannot implicitly convert
from: (struct OpaqueEventTargetRef *(*__pascal "Pascal")(void))
to : (struct OpaqueEventTargetRef *)
any suggestions people? I'm sure InstallEventHandler is the cause...

GetApplicationEventTarget() with brackets. You have to call the function, not pass its address

heh, plus &quitEventHandlerRef. thanks OneSadCookie, I'd just been confused with passing functions as pointers to NewEventHandlerUPP() beforehand.
