Hi, all
Is there any mature library which implements a global message
dispatching mechanism? I'm playing with wxpython in my spare time, and
I like the pubsub or pyDispatch module very much. Any object can
register a callable object to an event, and when this event happens the
callable object(or maybe more than one objects) is called.
I donnot like MFC's SendMessage() and PostMessage() because we must get
a hWnd at the same time. Maybe more than one object need to be called.
I cannot find such implementation in MFC.
I guess maybe someone has already made such a library, so could anybody
figure me out?

This is off-topic in this list. You should look in some Windows
specific list.
<OT>
Do you know about HWND_BROADCAST?
Take a look at SendMessage documention in msdn.microsoft.com

Sorry for the OT flag on any other list than comp.lang.c++, I didnīt
realise it was multiposted

We don't do MFC here.
Check out boost::signals http://www.boost.org/doc/html/signals.html
or libsigc http://libsigc.sourceforge.net/

This sounds to me like a standard observer pattern (see http://en.wikipedia.org/wiki/Observer_pattern ) or an event listener pattern
(see http://en.wikipedia.org/wiki/Event_listener )

DBUS perhaps?
The Windows port can be found here: http://sourceforge.net/projects/windbus
The main page and docs can be found here: http://www.freedesktop.org/wiki/Software/dbus
Hi, all
I'm sorry to reply so late.
HWND_BROADCAST is not exactly what I want, I want this message to be
sent to every registered functions, only top level windows can get the
HWND_BROADCAST message.
DBUS is not either. It seems that it is used in two different
applications while the mechanism which I need is only used in one
application.
Yes, what I need is exactly an observer pattern. And boost::signals &
libsigc are what I want, I'll look into them. Thanks for all your help!
Bruce
