Tkinter provides classes which allow the display, positioning and
control of widgets. Toplevel widgets are Tk and Toplevel. Other
widgets are Frame, Label, Entry, Text, Canvas, Button, Radiobutton,
Checkbutton, Scale, Listbox, Scrollbar, OptionMenu, Spinbox
LabelFrame and PanedWindow.
Properties of the widgets are specified with keyword arguments.
Keyword arguments have the same name as the corresponding resource
under Tk.
Widgets are positioned with one of the geometry managers Place, Pack
or Grid. These managers can be called with methods place, pack, grid
available in every Widget.
Actions are bound to events by resources (e.g. keyword argument
command) or with the method bind.
Example (Hello, World):
import tkinter
from tkinter.constants import *
tk = tkinter.Tk()
frame = tkinter.Frame(tk, relief=RIDGE, borderwidth=2)
frame.pack(fill=BOTH,expand=1)
label = tkinter.Label(frame, text="Hello, World")
label.pack(fill=X, expand=1)
button = tkinter.Button(frame,text="Exit",command=tk.destroy)
button.pack(side=BOTTOM)
tk.mainloop()

2) It is possible to give the name of an existing TK widget. These are

Classes:

This module also presents tk common file dialogues, it provides interfaces
to the native file dialogues available in Tk 4.2 and newer, and the
directory dialogue available in Tk 8.3 and newer.
These interfaces were written by Fredrik Lundh, May 1997.

FileDialoga� Standard file selection dialog -- no checks on selected file.
Usage:
d = FileDialog(master)
fname = d.go(dir_or_file, pattern, default, key)
if fname is None: ...canceled...
else: ...open file...
All arguments to go() are optional.
The 'key' argument specifies a key in the global dictionary
'dialogstates', which keeps track of the values for the directory
and pattern arguments, overriding the values passed in (it does
not keep track of the default argument!). If no key is specified,
the dialog keeps no memory of previous state. Note that memory is
kept even when the dialog is canceled. (All this emulates the
behavior of the Macintosh file selection dialogs.)
