I'm just learning PyQt and looking at the Signals and Slots mechanism. I'm a bit baffled by the verbose syntax. Why do we have:

self.connect(dial, SIGNAL("valueChanged(int)"), spinbox.setValue)

I would much prefer to write the following:

self.connect(dial.valueChanged, spinbox.setValue)

Can anyone tell me why the connect() syntax needs to be so explicit/verbose?

You can use PyQt's new style signals which are less verbose:

self.connect(dial, SIGNAL("valueChanged(int)"), spinbox.setValue)

Becomes:

dial.valueChanged.connect(spinbox.setValue)
