[PyKDE] A simple PyQt program

I'm having problem with a simple PyQt program I'm writing. It will 
eventually become a GUI frontend to the Unix 'watch' command, but for 
now, it's just a simple test. When I run the program, type in something 
into the "Command" text box, then click "OK," Python gives  me the 
following message:

TypeError: update() takes exactly 2 arguments (3 given)

I don't understand this, since I only gave update 2 arguments. If anyone 
could shed some light on this, I'd greatly appreciate it. Here's the code:

import sys, os
from qt import *
from kwatchui import frmKwatch
from kwatcherui import frmKwatcher

class dlgKwatch(frmKwatch):
    def __init__(self, parent=None):
        frmKwatch.__init__(self, parent)
        #this is old stuff
        #self.cmbHost.insertItem("another item")
    def accept(self):
        command = self.txtCommand.text()
        command = str(command)
        win2.update(self, command)

    def exec_help(self):

class dlgKwatcher(frmKwatcher):
    def __init__(self, parent=None):
        frmKwatcher.__init__(self, parent)
    def update(self, command):
    print 'Updating the text in "Kwatch - watching..."'

if __name__=='__main__':
    app = QApplication(sys.argv)
    QObject.connect(app, SIGNAL('lastWindowClosed()'), app, SLOT('quit()'))
    win = dlgKwatch()
    win2 = dlgKwatcher()

If you need the other files, I can attach them. Thanks.
