hi.

i am trying to learn event binding. i have a form with a couple of buttons
for different tags, which all call the same function. the text on the
buttons changes from record to record. this is the problem area:

    def showrecords(self):
        """this function updates the form labels to show the current
record"""
        global gmax
        global gctr
        global CurrTitle
        global CurrAuthor
        global CurrTag1
        global CurrTag2
        global CurrTag3
        global CurrTag4
        global CurrTag5
        global CurrAbstract
        global CurrLocation
        global CurrID
        global HuntFor

        self.Lbn.config(text=gmax)
        self.Lbnof.config(text=gctr+1)
        self.LbTitle.config(text=CurrTitle, justify=LEFT)
        self.LbName.config(text=CurrAuthor)
        self.LbPath.config(text=CurrLocation)
        self.BtTag1.bind('<Button-1>',self.calltotags(tag=CurrTag1))
        self.BtTag1.config(text=CurrTag1)
        self.BtTag2.bind('<Button-1>',self.calltotags(tag=CurrTag2))
        self.BtTag2.config(text=CurrTag2)
        self.BtTag3.bind('<Button-1>',self.calltotags(tag=CurrTag3))
        self.BtTag3.config(text=CurrTag3)
        self.BtTag4.bind('<Button-1>',self.calltotags(tag=CurrTag4))
        self.BtTag4.config(text=CurrTag4)
        self.BtTag5.bind('<Button-1>',self.calltotags(tag=CurrTag5))
        self.BtTag5.config(text=CurrTag5)
        self.LbAbs.config(text=CurrAbstract)

    def calltotags(event, tag):
        # This function sets the search variable HuntFor value, and calls
the tagwork class.
        global HuntFor
        global toggle
        HuntFor=tag
        toggle="Tagcluster"
        print HuntFor
        tagwork()

when i click on the buttons, none of them call the function. i only see the
huntfor value in the prompt when i load the program. can someone please
enlighten me as to why this happens? (the buttons are loaded on the root
window in an earlier function, and i have the same problem even if i try
binding the events there)

also, can someone suggest a good (and free!) code editor for python please?

thanks in advance.
mridula.
