It seems you may not even need the lambda. The QT docs say you can just
connect a signal to a signal (
http://doc.qt.nokia.com/latest/qobject.html#connect):i.QPushButton("Button
1"):
from PySide import QtCore, QtGui
class SignalToSignal(QtGui.QDialog):
custom_button_signal = QtCore.Signal()
def __init__(self, parent=None):
super(SignalToSignal, self).__init__(parent)
button = QtGui.QPushButton("Button 1")
vbox = QtGui.QVBoxLayout()
vbox.addWidget(button)
self.setLayout(vbox)
button.clicked.connect(self.custom_button_signal)
self.custom_button_signal.connect(self.say_hello)
def say_hello(self):
print "custom_button_signal says hi!"
import sys
app = QtGui.QApplication(sys.argv)
w = SignalToSignal()
w.show()
sys.exit(app.exec_())
