Most of the time, the Tkinter module is all you really
need, but a number of additional modules are available as well. The
Tk interface is located in a binary module named _tkinter.
This module contains the low-level interface to Tk, and should never
be used directly by application programmers. It is usually a shared
library (or DLL), but might in some cases be statically linked with
the Python interpreter.
In addition to the Tk interface module, Tkinter includes a
number of Python modules. The two most important modules are the
Tkinter module itself, and a module called
Tkconstants. The former automatically imports the latter, so
to use Tkinter, all you need to do is to import one module:
The Tk class is instantiated without arguments.
This creates a toplevel widget of Tk which usually is the main window
of an application. Each instance has its own associated Tcl interpreter.
Changed in version 2.4:
The useTk parameter was added.
The Tcl function is a factory function which creates an
object much like that created by the Tk class, except that it
does not initialize the Tk subsystem. This is most often useful when
driving the Tcl interpreter in an environment where one doesn't want
to create extraneous toplevel windows, or where one cannot (such as
Unix/Linux systems without an X server). An object created by the
Tcl object can have a Toplevel window created (and the Tk
subsystem initialized) by calling its loadtk method.
New in version 2.4.
