Tk button enable/disable?

[Kevin Cazabon]

Well, using normal Tk buttons (through Tkinter), you would call the
following:

whateverTheButtonNameIs.config(state = Normal)

I don't use Pmw very much, but you'd have to know if the Button instance is
"self.newButton", or maybe a subvalue of self.newButton (like
self.newButton.button or whatever).
