Which of the two ways of emitting a signal from a derived class is better?

[piotr.dobrogost]

Which of the following two ways of emitting a signal from my class which inherits from some class with signals is better and why?

1. Emitting my signal from within overridden method of a base class like QAbstractState::onEntry().

2. Creating handler for base class' signal like QAbstractState::entered(), connecting the signal with the handler and emitting my signal from within this handler.

It doesn't matter. The second solution though enables someone to disconnect the signal if (s)he wants to. This might be both a good or a bad thing :)
