[Tkinter-discuss] Possibly n00bish question about ImageTk

[Barnesdesdes]

I've been trying to make a program which will import a png file and display
it inside a frame.  It actually works when I just run the code, but if I try
to abstract the exact same code into a function, it fails.  In the code
below, if I just run it, it works.  However, if I comment out the lines
between "root=Tkinter.Tk()" and "moo(root)" and comment in "moo(root)", it
no longer works.  Instead of displaying the image, it just displays a gray
frame of the correct size.  Does anyone have any insights about what I'm
doing wrong?

import Image, ImageTk, Tkinter

def moo(master):
    img = Image.open('plotfig.png')
    f = Tkinter.Frame(master, width=800, height=600)
    pi = ImageTk.PhotoImage(img)
    t = Tkinter.Label(f, image=pi)
    f.pack()
    t.place(x=0, y=0, width=800, height=600)
    t.pack()

root = Tkinter.Tk()
img = Image.open('plotfig.png')
f = Tkinter.Frame(root, width=800, height=600)
pi = ImageTk.PhotoImage(img)
t = Tkinter.Label(f, image=pi)
f.pack()
t.place(x=0, y=0, width=800, height=600)
t.pack()
#moo(root)
root.mainloop()


Thanks very much.

Alan
