Problems with Pmw

[David LeBlanc]

You have to initialize Pmw and that's not the way to create a top level
window.
Try this:

from Tkinter import *
root = Tk()
import Pmw
Pmw.initialise(root)

t2 = Toplevel()
l = Label(t2, text='A label') ; l.pack()
b = Button(t2, text='Press me') ; b.pack()
e = Pmw.EntryField(t2, labelpos=W, label_text='Enter something') ; e.pack()
t2.mainloop()
