How to find an object existing?

[huey.y.jiang at gmail.com]

Hi All,

root = Tkinter.Tk()
button = Tkinter.Button(root, text="Find me")
button.pack()

I created a button, Python object. I recall I can check this object existing by using   winfo, such as  winfo.exists(button). However, I forgot which super class contains this   winfo   method.  I printed out dir(os), dir(sys), dir(Tkinter), but did not find this winfo method. I wonder who will be kindly drop down a few lines? Thanks a lot!
