\details{
  These functions create Tk widgets.  \code{tkwidget} creates a widget of
  a given type, the others simply call \code{tkwidget} with the
  respective \code{type} argument.

  The functions starting \code{ttk} are for the themed widget set for Tk
  8.5 or later.  A tutorial can be found at \url{http://www.tkdocs.com}.

  It is not possible to describe the widgets and their arguments in
  full.  Please refer to the Tcl/Tk documentation.
