TKinter, buttonwidget response problem(1) and all btns the same size(2)!

[skanemupp at yahoo.se]

am i not doing that then? did u look at the code? where do i add the
bind if this:
btnDisplay = Button(self, text="1", command=self.Display)
        btnDisplay.grid(row=3, column=0, padx=5, pady=5)

is not enough?



def Display(self, event_obj):
        button = event_obj.widget
        text = button.cget("text")

        if text=="1":
            print 1
