Scope <or> PyQt question

[dittonamed]

Code pasted below ----->

Can anyone out there suggest a way to access the object "p" thats
started in playAudio() from inside the stopAudio()? I need the object
reference to use QProcess.kill() on it. The code sample is below.
Thanks to anyone who helps out =)

More comments in the code below  ------>


from qt import *

class Form2(QMainWindow):
    def __init__(self,parent = None,name = None,fl = 0):
        QMainWindow.__init__(self,parent,name,fl)
        self.statusBar()

    def playAudio(self):
        p = QProcess(self, 'player')
        playcmd = '/usr/bin/play'
        filename = 'song.ogg'
        p.addArgument(playcmd)
        p.addArgument(filename)
        p.start()

    def stopAudio(self):
        ''' #This is just to show that i can "see" the object, though
i
           #dont know how to "access" it
           #the output shows the QProcess object by name...
           # but how do i reference it??
        allobjs = list(QObject.objectTrees())
        for obj in allobjs:
                objName = QObject.name(obj)
                if objName == 'Form2':
                        print QObject.children(obj)
        '''

        QProcess.kill(NEED THE REFERENCE HERE)
