PyQt connect SIGNAL to multiple SLOT

Question

I am trying to learn PyQt from rapid gui programming with python and qt and currently learning Signals and Slots.

Answer 1

You can use a list to connect the two slots/functions in a single statement:

# in Python 2.X
map(self.dial.valueChanged.connect, [self.spinbox.setValue, self.getValue_dial])

# in Python 3.X (map returns an iterator instead of processing the list)
list(map(self.dial.valueChanged.connect, [self.spinbox.setValue, self.getValue_dial]))

# or with any Python version
[self.dial.valueChanged.connect(x) for x in [self.spinbox.setValue, self.getValue_dial]]
