They both work well together, provided that a couple of tweaks are done 
so that Qt's symbols don't clash with libsigc++'s.  If I'm not mistaken, 
all that's needed to mix libsigc++ with Qt's signals and slots is to 
include libsigc++'s headers before any Qt header, and refer to Qt's 
signals and slots through the Q_SIGNALS and Q_SLOTS keyword.  It has 
also been suggested that a #define QT_NO_KEYWORDS is also added to the 
source code files where libsigc++ is used.

I've developed a small program where I've used libsigc++ with Qt and, by 
following this, I haven't had any problem whatsoever.


Hope this helps,
