5 :synopsis: Interface to Tcl/Tk for graphical user interfaces
13 The :mod:`tkinter` package ("Tk interface") is the standard Python interface to
14 the Tcl/Tk GUI toolkit. Both Tk and :mod:`tkinter` are available on most Unix

19 properly installed on your system, and also showing what version of Tcl/Tk is
20 installed, so you can read the Tcl/Tk documentation specific to that version.

97 Tk uses Tcl's event queue to generate and process GUI events.
100 Themed Tk (Ttk) is a newer family of Tk widgets that provide a much better
101 appearance on different platforms than many of the classic Tk widgets.
102 Ttk is distributed as part of Tk, starting with Tk version 8.5. Python

465 Tcl/Tk applications are normally event-driven, meaning that after initialization,
466 the interpreter runs an event loop (i.e. :func:`Tk.mainloop`) and responds to events.
