PySide event handling: pos versus globalpos

I'm playing around with Qt in Python using PySide. It is one of the steepest learning curves I've ever been on. I figure I'll start dropping little examples here. The following is a really simple example to demonstrate the difference between the pos and globalPos of an event in a window. Fire up the program, click within the window, and then drag the window and click within it again. It will print out globalPos() and pos() of a mouse click in the command line, and should be fairly self-explanatory.

from PySide import QtGui, QtCore  
   
class MousePos(QtGui.QWidget):  
    def __init__(self):  
        QtGui.QWidget.__init__(self)  
        self.initUI()  
       
    def initUI(self):  
        self.setGeometry(50,50,300,250)  
        self.show()  
   
    def mousePressEvent(self,event):  
        if event.button() == QtCore.Qt.LeftButton:  
            msg="event.globalPos: <{0}, {1}>\n".format(event.globalPos().x(), event.globalPos().y())  
            msg2="event.pos(): <{0}, {1}>\n".format(event.pos().x(), event.pos().y())  
            print msg + "  " + msg2  
       
def main():  
    import sys  
    qtApp=QtGui.QApplication(sys.argv)  
    myMousePos=MousePos()  
    sys.exit(qtApp.exec_())  
   
if __name__=="__main__":  
    main()  

One of my goals is to see if this code formatting worked in blogger. I did it at codeformatter.blogspot.com but am looking for better ways to do it. I want examples to be simple: cut, paste, and it works in your interpreter. Python is all about using space for syntax, and I had to do too much futzing to get the syntax right.
