[Pyrex] staticforward

[Bryan Weingarten]

please,

i really need help solving this.  please don't give up on me yet.   here's
is the complete code of what i have now that is relevant to this problem.
when the status method is like i have in the example, it the c-extension
crashes. but if i have it as a nested or global function (see the #
comments) it works correctly.

thank you,

bryan

class MyPlay:
    def status(self, sec, msec):  # never gets called
        print sec, msec, self.data
        return 1

    def play(self, mp3file):
        # def status(sec, msec):  # this works
        #       print sec, msec, self.data
        #       return 1

        self.data = ('test', 2.0, {1:'one'})
        m = mpgedit.Play(mp3file)
        m.status_callback(self.status) #crashes the c-extension
        # m.status_callback(status) # this works
        while(m.play_frame()): pass

    m = MyPlay()
    m.play(sys.argv[1])
