DEFINITIONS

19       Each widget is assigned a style, which specifies the  set  of  elements
20       making  up the widget and how they are arranged, along with dynamic and
21       default settings for element options.  By default, the  style  name  is
22       the  same  as  the widget's class; this may be overridden by the -style
23       option.
24
25       A theme is a collection of elements and styles which controls the over‐
26       all look and feel of an application.

DESCRIPTION

29       The ttk::style command takes the following arguments:
30
31       ttk::style configure style ?-option ?value option value...? ?
32              Sets the default value of the specified option(s) in style.
33
34       ttk::style map style ?-option { statespec value... }?
35              Sets  dynamic  values of the specified option(s) in style.  Each
36              statespec / value pair is examined in order;  the  value  corre‐
37              sponding to the first matching statespec is used.
38
39       ttk::style lookup style -option ?state ?default??
40              Returns  the value specified for -option in style style in state
41              state, using the standard  lookup  rules  for  element  options.
42              state  is  a list of state names; if omitted, it defaults to all
43              bits off (the “normal”  state).   If  the  default  argument  is
44              present, it is used as a fallback value in case no specification
45              for -option is found.
46
47       ttk::style layout style ?layoutSpec?
48              Define the widget layout for style style.  See LAYOUTS below for
49              the  format of layoutSpec.  If layoutSpec is omitted, return the
50              layout specification for style style.
51
52       ttk::style element create elementName type ?args...?
53              Creates a new element in the current theme of  type  type.   The
54              only   cross-platform   built-in  element  type  is  image  (see
55              ttk_image(n)) but themes may define  other  element  types  (see
56              Ttk_RegisterElementFactory).  On suitable versions of Windows an
57              element factory is registered to create Windows  theme  elements
58              (see ttk_vsapi(n)).
59
60       ttk::style element names
61              Returns the list of elements defined in the current theme.
62
63       ttk::style element options element
64              Returns the list of element's options.
65
66       ttk::style   theme   create   themeName  ?-parent  basedon?  ?-settings
67       script... ?
68              Creates a new theme.   It  is  an  error  if  themeName  already
69              exists.   If  -parent  is  specified, the new theme will inherit
70              styles, elements, and layouts from the parent theme basedon.  If
71              -settings  is present, script is evaluated in the context of the
72              new theme as per ttk::style theme settings.
73
74       ttk::style theme settings themeName script
75              Temporarily  sets  the  current  theme  to  themeName,  evaluate
76              script,  then restore the previous theme.  Typically script sim‐
77              ply defines styles and elements, though arbitrary Tcl  code  may
78              appear.
79
80       ttk::style theme names
81              Returns a list of all known themes.
82
83       ttk::style theme use ?themeName?
84              Without an argument the result is the name of the current theme.
85              Otherwise this command sets the current theme to themeName,  and
86              refreshes all widgets.

LAYOUTS

89       A  layout  specifies  a  list of elements, each followed by one or more
90       options specifying how to arrange the element.   The  layout  mechanism
91       uses  a  simplified version of the pack geometry manager: given an ini‐
92       tial cavity, each element is allocated a parcel.  Valid options are:
93
94       -side side
95              Specifies which side of the cavity to place the element; one  of
96              left,  right,  top, or bottom.  If omitted, the element occupies
97              the entire cavity.
98
99       -sticky [nswe]
100              Specifies where the element is placed inside its allocated  par‐
101              cel.
102
103       -children { sublayout... }
104              Specifies a list of elements to place inside the element.
105
106       For example:
107              ttk::style layout Horizontal.TScrollbar {
108                  Scrollbar.trough -children {
109                      Scrollbar.leftarrow -side left
110                      Scrollbar.rightarrow -side right
111                      Horizontal.Scrollbar.thumb -side left -sticky ew
112                  }
113              }
