<h3>Apple "Quit" Event</h3>
|
||||
|
||||
<P>When the user press Cmd-Q or requests a termination of the
|
||||
application, OS X will send a "Quit" Apple Event. FLTK handles
|

this event by sending an <tt>FL_CLOSE</tt> event to all open
|
||||
windows. If all windows close, the application will terminate.
|

|
||||
<h3>Apple "Open" Event</h3>
|
||||
|
||||
Whenever the user drops a file onto an application icon, OS X
|
||||
generates an Apple Event of the type "Open". You can have FLTK
|
||||
notify you of an Open event by setting the <tt>fl_open_callback</tt>.
