What is the correct method of handling events in PyQt 4?

Question

I have seen examples like this:

self.connect(self.ui.add_button, QtCore.SIGNAL('clicked()'),self.printer)

And examples like this:

self.ui.add_button.clicked.connect(self.printer)

I'm just starting to learn Qt; which one should I focus on?

Answer 1

I think that the second example is only supported by some Qt versions (the newer ones), while the first it supported by older ones. But, both are correct.
