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 application.

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 examined 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 fallback 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(3tk)) 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(3tk)).

       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
                  }
              }
