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 over‐
all 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 corre‐
sponding 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(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 sim‐
ply 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 ini‐
tial 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 par‐
cel.
-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
}
}
