I spent about a week solving the problem I have in this code but I
couldn't do anything. I just give up working due to that line of code.
What I need is that:
I have a main window with an "oval menu bar" and under the menu-bar, there is a
" Add Oval&quo

See http://wiki.python.org/moin/TkInter for a list of references.
For me John Shipman's Tkinter Reference is normally sufficient.

As I said: I do
e handler for all shapes:
def handler(event):
print event.widget.gettags("current")[0], "got hit"
canvas.tag_bind('oval1', '', handler)
canvas.tag_bind('oval2', '', handler)
I prefer one handler per shape:
def make_handler(message):
def handler(event):
print message
return handler
canvas.tag_bind('oval1', '', make_handler("oval 1 got hit"))
canvas.tag_bind('oval2', '', make_handler("oval 2 got hit"))

I tested the following code and wanted to get the message of "oval2
got hit" if I click the red one. But I always got "oval1 got hit".
from Tkinter import *
root=Tk()
canvas=Canvas(root,width=100,height=100)
canvas.pack()
a=canvas.create_oval(10,10,20,20,tags='oval1',fill='blue')
b=canvas.create_ov
