I have many menu items and would like them all to call the same method -However, I need the method called to react differently depending on the menu item selected. Since the menu command functions do not seem to receive any type of event style object, is there some type of Tkinter call that would let my method know the menu id selected ?
Much as it seems to be out of favor, IMO this is a place where a lambda expression is very handy. You can make a callback for each menu item that binds an extra parameter to the handler:
# Based on an example by Fredrik Lundh from Tkinter import *
def callback(code):
print "called the callback with code", coderoot = Tk()
# create a menu menu = Menu(root) root.config(menu=menu)
filemenu = Menu(menu)
menu.add_cascade(label="File", menu=filemenu)
filemenu.add_command(label="New", command=lambda: callback('New'))
filemenu.add_command(label="Open...", command=lambda: callback('Open'))
filemenu.add_separator()
filemenu.add_command(label="Exit", command=lambda: callback('Exit'))mainloop()
Of course you could do this with named forwarding functions if you prefer.
