PySide : How to get the clicked QPushButton object in the QPushButton clicked slot?

Here is what I did to solve the problem:

button = QtGui.QPushButton("start go")
button.clicked.connect(lambda: self.buttonClick(button))

def buttonClick(self, button):
    print button.text()

You can just use self.sender() to determine the object that initiated the signal.

In your code something along the lines of this should work.

button = QtGui.QPushButton("start go")
button.clicked.connect(self.buttonClick)

def buttonClick(self):
    print self.sender().text()
