example Tkinter code?

[richard_chamberlain]

Hi,

Have a look at John Grayson's manning site (www.manning.com/grayson) you can
download the source from his book including code that demonstrates each
widget.

I really would recommend a copy as it's an excellent book.

from Tkinter import *
root=Tk()
myString=StringVar()
Label(root,textvariable=myString).pack()
myString.set("Well, eh, how about a little red Leicester.")
def changeLabel():
    myString.set("I'm, a-fraid we're fresh out of red Leicester, sir. ")
Button(root,text='Click Me',command=changeLabel).pack()
root.mainloop()

I presume where you're going wrong is you are not creating an instance of
StringVar and setting (or getting) the variable through that.
