PyQt... What am I doing wrong?!

[Richie]

Hi guys, just starting out with Qt using PyQt, and not having a great time! Anyone help me out here... I'm trying to get a button to print "hello world". Stereotypical and unimaginative, I know, but hey, you have to start somewhere! Problem is, I click it and nothing happens! It's not even calling the function. I think my connect statement is rubbish. Can you help?

Ta,

Rich

from PyQt4 import QtCore, QtGui

class Ui_About(object):
    def setupUi(self, Dialog):
        Dialog.setObjectName("Dialog")
        Dialog.resize(388, 336)
        self.btnOK = QtGui.QPushButton(Dialog)
        self.btnOK.setGeometry(QtCore.QRect(130, 300, 110, 23))
        self.btnOK.setObjectName("btnOK")
 
        QtCore.QObject.connect(self.btnOK, QtCore.SIGNAL("clicked()"), self.hello)
        QtCore.QMetaObject.connectSlotsByName(Dialog)
 
    def hello(self):
        print "hello world"

class Ui_About(object):
    def setupUi(self, Dialog):
        Dialog.setObjectName("Dialog")
        Dialog.resize(388, 336)
        self.btnOK = QtGui.QPushButton(Dialog)
        self.btnOK.setGeometry(QtCore.QRect(130, 300, 110, 23))
        self.btnOK.setObjectName("btnOK")

        QtCore.QObject.connect(self.btnOK, QtCore.SIGNAL("clicked()"), self.hello)
        QtCore.QMetaObject.connectSlotsByName(Dialog)

    def hello(self):
        print "hello world"
