Bitmaps in Tkinter

[Hans Kristian Ruud]

I am teaching myself Tkinter programming from the book
'Python and Tkinter programming' by John  E. Grayson.

I have a problem with bitmaps: e.g.when I try to run the example on p.
59:

from Tkinter import *
import Pmw

bitmap_path = 'D:\\usr\\X11R6.4\\include\\X11\\bitmaps\\'
root = Tk()
Pmw.initialise()

balloon = Pmw.Balloon(root)
menuBar = Pmw.MenuBar(root, hull_relief=RAISED, hull_borderwidth=1,
  balloon=balloon)
menuBar.pack(fill=X)
menuBar.addmenu('Buttons', 'Simple Commands')
menuBar.addmenuitem('Buttons', 'command', 'Close this window',
  font=('StingerLight', 14), label='Close')
menuBar.addmenuitem('Buttons', 'command', bitmap="@bitmaps\\RotateLeft",

  foreground='Yellow')
menuBar.addmenuitem('Buttons', 'separator')
menuBar.addmenuitem('Buttons', 'command',
  'Exit the application', label='Exit')

menuBar.addmenu('Cascade', 'Cascading Menus')
menuBar.addmenu('Checkbutton', 'Checkbutton Menus')
menuBar.addmenu('Radiobutton', 'Radiobutton Menus')

root.mainloop()


I get this output:

D:\drsc\exercizes>MenuBar.py
Traceback (innermost last):
  File "D:\drsc\EXERCI~1\MenuBar.py", line 16, in ?
    foreground='Yellow')
  File "D:\program files\Python\Pmw\Pmw_0_8_4\lib\PmwMenuBar.py", line
171, in
addmenuitem
    apply(command, (), kw)
  File "D:\program files\Python\Lib\lib-tk\Tkinter.py", line 1517, in
add_command
    self.add('command', cnf or kw)
  File "D:\program files\Python\Lib\lib-tk\Tkinter.py", line 1510, in
add
    self.tk.call((self._w, 'add', itemType) +
TclError: error reading bitmap file "bitmaps\RotateLeft"


Any ideas?

- thanks in advance -
