Hi,

Im having trouble with the piece of code below, i want to have the image change every time you press the button. This code is from a larger project but this is the bit that i cant get to work.

Any ideas?



python Syntax (Toggle Plain Text) 
  1. import Tkinter
  2. import random
  3. import Image, ImageTk
  4.  
  5. def changeImage():
  6.  
  7.     listOfImages = ["r7", "A", "C", "B", "b7", "f", "P", "G", "O"]
  8.     im = listOfImages[random.randint(0,8)]
  9.     box1Label.configure(image=im)
  10.  
  11. top = Tkinter.Tk()
  12.  
  13. r7 = ImageTk.PhotoImage(file="gfx/r7.jpg")
  14. b7 = ImageTk.PhotoImage(file="gfx/b7.jpg")
  15. A = ImageTk.PhotoImage(file="gfx/A.jpg")
  16. B = ImageTk.PhotoImage(file="gfx/B.jpg")
  17. C = ImageTk.PhotoImage(file="gfx/C.jpg")
  18. f = ImageTk.PhotoImage(file="gfx/f.jpg")
  19. G = ImageTk.PhotoImage(file="gfx/G.jpg")
  20. P = ImageTk.PhotoImage(file="gfx/P.jpg")
  21. O = ImageTk.PhotoImage(file="gfx/O.jpg")
  22.  
  23.  
  24. box1Label = Tkinter.Label(top, image=r7)
  25. box1Label.grid(row=3, column=2)
  26.  
  27. changeButton = Tkinter.Button(top, text="Change", command=changeImage)
  28. changeButton.grid(row=9, column=7)
  29.  
  30. Tkinter.mainloop()

Note that the images are objects not strings, so you have to do this ...
python Syntax (Toggle Plain Text) 
  1. import Tkinter
  2. import random
  3. import Image, ImageTk
  4.  
  5. def changeImage():
  6.     global listOfImages
  7.     im = listOfImages[random.randint(0,8)]
  8.     box1Label.configure(image=im)
  9.  
  10. top = Tkinter.Tk()
  11. r7 = ImageTk.PhotoImage(file="gfx/r7.jpg")
  12. b7 = ImageTk.PhotoImage(file="gfx/b7.jpg")
  13. A = ImageTk.PhotoImage(file="gfx/A.jpg")
  14. B = ImageTk.PhotoImage(file="gfx/B.jpg")
  15. C = ImageTk.PhotoImage(file="gfx/C.jpg")
  16. f = ImageTk.PhotoImage(file="gfx/f.jpg")
  17. G = ImageTk.PhotoImage(file="gfx/G.jpg")
  18. P = ImageTk.PhotoImage(file="gfx/P.jpg")
  19. O = ImageTk.PhotoImage(file="gfx/O.jpg")
  20. # images are objects not strings
  21. listOfImages = [r7, A, C, B, b7, f, P, G, O]
  22.  
  23. box1Label = Tkinter.Label(top, image=r7)
  24. box1Label.grid(row=3, column=2)
  25. changeButton = Tkinter.Button(top, text="Change", command=changeImage)
  26. changeButton.grid(row=9, column=7)
  27.  
  28. Tkinter.mainloop()
May 'the Google' be with you!
