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 built-in element type is image (see ttk_image(n)), although
themes may define other element types (see Ttk_RegisterElementFactory).
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, ele-
ments, 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
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
}
}
