André already said it (and I agree), but I'll assert clearly:
"moc" is a code generator.
You get stuff with a code generator that is not possible with
function

Subject: [Interest] A suggestion about replacing signals, actions and slots
Hello,
I read http://byuu.org/articles/qt and got a question, why Qt uses slots and

Hello,
I read http://byuu.org/articles/qt and got a question, why Qt uses slots and

can give some advantages.
For instance, for now we need to use something like this to connect callbacks
(actions):
connect
