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 seems silly to connect an object to itself, I should be able to simply override the textChange method -- but it isn't virtual.
What is the accepted way to do this?
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 !
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)) );
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)
