These functions create Tk widgets. tkwidget creates a widget of
a given type, the others simply call tkwidget with the
respective type argument.
The functions starting ttk are for the themed widget set for Tk
8.5 or later. A tutorial can be found at http://www.tkdocs.com.
It is not possible to describe the widgets and their arguments in
full. Please refer to the Tcl/Tk documentation.
