Why is PyQt connect() syntax so verbose?

Question

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(\         


        

Answer 1

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)

Answer 2

Luper's answer is much better than this one, but for the sake of completeness...

The ugly "old style" syntax is an anachronism from the C++ world - just look at the syntax those guys have to work with! Yucky...

Answer 3

An even shorter way is to assign the signal name to the function in the keyword arguments of the constructor e.g. QDial(valueChanged=spinbox.setValue). PyQt will automatically connect the valueChanged() signal to spinbox.setValue().
