How to process signals in a Qt subclass?

Question

How do I process a signal of in a subclass? Let\'s say my subclass is derived from QTextEdit and is interested in the signal textChanged. It seem

Answer 1

It is perfectly ok to connect a signal to a slot in the same class. So implement your slot and connect it to textChanged(QString)

Answer 2

You can't implement/override a signal, so the only way is to create a new slot and connect it to textChanged():

connect( this, SIGNAL(textChanged(QString)), this, SLOT(slotTextChanged(QString)) );

Answer 3

Maybe it seems silly, but that's the way I did it : connecting my derived class to the signal emited by the parent class.

But I'm interested if there are any other solutions !
