problem with tk and pass by refference (I think :)

Hi,

button = Button(self.songWin, text=verse, command=(lambda num=verseNum:
self.showVerse(num)) )

should do the trick. The reason is basically that your version kept a
reference to verseNum - and when executed, the value verseNum points to is
the lasts one stored.

Rebinding the argument to a parameter in the lambda will keep the right
value for each iteration.
