[gentoo-amd64] Qt tutorial 7 - anyone got this to work?

[Daiajo Tibdixious]

This is probably off-topic, so suggestions to go elsewhere are welcome.
I reported this to trolltech as a bug, but it doesn't show in their
task tracker.
http://doc.trolltech.com/4.2/tutorial-t7.html
Introduces creating ones own signals & slots.
slots seem to work fine but signals are not found in a connect call.
I can't see any difference between the Qt supplied signals (in their
includes), and my ones.

Another funny is that the Q_OBJECT macro works fine in the Qt includes,
however if used in my program, linker vtable errors occur caused by
the virtual functions declared by the macro.

I should probably tell you to read the documentation. What happens is that you 
must include the macro, AND, run moc on your file which creates another C++ 
file that you must also compile (and link). The easiest way to build qt 
projects is to use qmake which handles it for you.
