Quit from the OSX-dock

[R. Hillen]

Hello list,

if I start a RunRev-standalone on  OSX, it appears as an icon in the 
dock and can be quitted from there.

Somebody knows, which message is sent, if I use the dock to quit the 
standalone, so that I can do the final things (like save changed data) 
before the application quits?

(I tried shutdownrequest, but it failed)

Thanx for your hints
