DEFINITIONS
       Each widget is assigned a style, which specifies the set of elements making up  the  widget  and  how
       they  are  arranged,  along  with  dynamic and default settings for element options.  By default, the
       style name is the same as the widget's class; this may be overridden by the -style option.

       A theme is a collection of elements and styles which controls the overall look and feel of an  appli-cation. application.
       cation.

DESCRIPTION
       The ttk::style command takes the following arguments:

       ttk::style configure style ?-option ?value option value...? ?
              Sets the default value of the specified option(s) in style.

       ttk::style map style ?-option { statespec value... }?
              Sets dynamic values of the specified option(s) in style.  Each statespec / value pair is exam-ined examined
              ined in order; the value corresponding to the first matching statespec is used.

       ttk::style lookup style -option ?state ?default??
              Returns the value specified for -option in style style in  state  state,  using  the  standard
              lookup  rules for element options.  state is a list of state names; if omitted, it defaults to
              all bits off (the "normal" state).  If the default argument is present, it is used as a  fall-back fallback
              back value in case no specification for -option is found.

       ttk::style layout style ?layoutSpec?
              Define the widget layout for style style.  See LAYOUTS below for the format of layoutSpec.  If
              layoutSpec is omitted, return the layout specification for style style.

       ttk::style element create elementName type ?args...?
              Creates a new element in the current theme of type type.   The  only  cross-platform  built-in
              element  type  is  image  (see  ttk_image(n))  but  themes may define other element types (see
              Ttk_RegisterElementFactory). On suitable versions of Windows an element factory is  registered
              to create Windows theme elements (see ttk_vsapi(n)).

       ttk::style element names
              Returns the list of elements defined in the current theme.

       ttk::style element options element
              Returns the list of element's options.

       ttk::style theme create themeName ?-parent basedon? ?-settings script... ?
              Creates  a  new  theme.  It is an error if themeName already exists.  If -parent is specified,
              the new theme will inherit styles, elements, and layouts from the parent  theme  basedon.   If
              -settings  is  present,  script is evaluated in the context of the new theme as per ttk::style
              theme settings.

       ttk::style theme settings themeName script
              Temporarily sets the current theme to themeName, evaluate script, then  restore  the  previous
              theme.   Typically  script  simply  defines styles and elements, though arbitrary Tcl code may
              appear.

       ttk::style theme names
              Returns a list of all known themes.

       ttk::style theme use ?themeName?
              Without an argument the result is the name of the current theme.  Otherwise this command  sets
              the current theme to themeName, and refreshes all widgets.

LAYOUTS
       A layout specifies a list of elements, each followed by one or more options specifying how to arrange
       the element.  The layout mechanism uses a simplified version of the pack geometry manager:  given  an
       initial cavity, each element is allocated a parcel.  Valid options are:

       -side side
              Specifies  which  side of the cavity to place the element; one of left, right, top, or bottom.
              If omitted, the element occupies the entire cavity.

       -sticky [nswe]
              Specifies where the element is placed inside its allocated parcel.

       -children { sublayout... }
              Specifies a list of elements to place inside the element.

       For example:
              ttk::style layout Horizontal.TScrollbar {
                  Scrollbar.trough -children {
                      Scrollbar.leftarrow -side left
                      Scrollbar.rightarrow -side right
                      Horizontal.Scrollbar.thumb -side left -sticky ew
                  }
              }
