I'm afraid this is coming late for your assignment then. For the next time:
- Try to isolate the problem. Start with your current, full program, and
strip down sections (one at a time) and see whether the problem is still
present or not. Eventually, you'll get working code (so you know the last
removed section was the culprit) or it becomes so small that you cannot
simplify it further.
(You posted a very long program, most of it irrelevant for this question)
- Explain how to reproduce the problem, what you got, and what you
expected to get. (You posted what you got, but not what you expected. I
had to *imagine* that those funny squares were supposed to contain an
This is a heavily stripped down version of your program that still shows
b['image'] = image
b['text'] = ''
root = Tkinter.Tk()
image = Tkinter.PhotoImage(file="1.gif")
b = Tkinter.Button(root, width=3, height=2, command=callback)
b['text'] = 'X'
If you remove the 'width' and 'height' specifications, it works fine. Now
look at the documentation, from http://effbot.org/tkinterbook/button.htm :
"height= The height of the button. If the button displays text, the size
is given in text units. If the button displays an image, the size is given
in pixels (or screen units). If the size is omitted, it is calculated
based on the button contents. (height/Height)
width= The width of the button. If the button displays text, the size is
given in text units. If the button displays an image, the size is given in
pixels (or screen units). If the size is omitted, or zero, it is
calculated based on the button contents. (width/Width)"
Initially the button contains text, so width=3 and height=2 are in
character units. When you set an image, the same values are interpreted in
Replace the callback function with this one, or some variant:
(btw, notice usage of config() to set widget attributes, and implicit line
continuation instead of \ )
