tablelist::setTheme
    Commandtablelist::getCurrentTheme Commandtablelist::getThemes
    Commandtablelist::setThemeDefaults CommandThe commands described in this reference page should only be invoked when using the package Tablelist_tile. They enable you to set and query the current theme, to retrieve a list of the available themes, and to make sure that your widgets will have a theme-specific appearance.
tablelist::setTheme Commandtablelist::setTheme – Set the current themetablelist::setTheme theme
theme,
    loading it if necessary.  It is simply an alias for
    ttk::setTheme or tile::setTheme,
    depending on the tile version loaded into the interpreter.  (The
    tile::setTheme command was renamed to
    ttk::setTheme in tile version 0.8.)tablelist::setTheme command does exactly the same as
    the original one: It loads the package implementing the given theme if
    needed, sets the theme to the specified one, and saves the latter in the
    variable ttk::currentTheme or
    tile::currentTheme, depending on the current tile
    version.tablelist::getCurrentTheme
  Commandtablelist::getCurrentTheme – Get the current
    themetablelist::getCurrentTheme
ttk::style theme use  command.  If
    an old tile version is being used which doesn't yet support this method
    then the command returns the value of the variable
    ttk::currentTheme or
    tile::currentTheme, depending on the tile
    version.  (The namespace containing the variable
    currentTheme was changed in tile version 0.8 from
    tile to ttk.)tablelist::getThemes Commandtablelist::getThemes – Get the themes registered in
    the package databasetablelist::getThemes
ttk::themes
    or tile::availableThemes, depending on the tile version
    loaded into the interpreter.  (The
    tile::availableThemes command was renamed to
    ttk::themes in tile version 0.8.)tablelist::setThemeDefaults
  Commandtablelist::setThemeDefaults – Set theme-specific
    default values of some tablelist configuration optionstablelist::setThemeDefaults
tablelist::themeDefaults with theme-specific default
    values of a series of Tablelist configuration options.  The array
    names are the command-line names of the options, and the corresponding
    array values are the default values of these configuration options for the
    currently set tile theme.tablelist::themeDefaults are:
    -background, -foreground,
    -disabledforeground,
    -stripebackground,
    -selectbackground,
    -selectforeground,
    -selectborderwidth, -font,
    -labelforeground, -labelfont,
    -labelborderwidth, -labelpady,
    -arrowcolor, -arrowdisabledcolor,
    -arrowstyle, and -treestyle. 
    In addition, the command sets some other array elements to theme-specific
    default values of the background and foreground colors of the column labels
    in normal, disabled,
    active, and pressed states. 
    (Tablelist needs the label colors for handling sort arrows and images with
    transparent background in the column labels.)tablelist::setThemeDefaults command
    is invoked by Tablelist_tile automatically at application start time and
    when the <<ThemeChanged>> virtual event is
    sent to the main window.  It is also invoked on Mac OS 10.14 (Mojave)
    and later whenever the main window receives a
    <<LightAqua>> or
    <<DarkAqua>> virtual event, if the current
    theme is aqua.  In these cases, after invoking the
    tablelist::setThemeDefaults command, Tablelist_tile
    sends the virtual event
    <<TablelistThemeDefaultsChanged>> to the
    main window and reconfigures all tablelist widgets of the application,
    using the new default values of those options that were not set explicitly
    to values different from the corresponding defaults.<<LightAqua>> and
    <<DarkAqua>> are sent by Tk 8.6.10 and
    later to all toplevel widgets whenever the system appearance toggles
    between Light Mode and Dark Mode or the Accent Color in the General
    Preferences changes.  Tk versions 8.6.11 and later send these events
    on Mac OS 10.15 (Catalina) and later also when changing the Highlight Color
    in the General Preferences.tablelist::themeDefaults,
    you can make sure that classical Tk widgets, e.g., listbox and text, will
    have a theme-specific appearance, just like the tile widgets.  For
    example, you can add some common configuration options to the option
    database as follows:
        
tablelist::setThemeDefaults
if {[tk windowingsystem] eq "x11"} {
    option add *selectBackground  $tablelist::themeDefaults(-selectbackground)
    option add *selectForeground  $tablelist::themeDefaults(-selectforeground)
}
option add *selectBorderWidth     $tablelist::themeDefaults(-selectborderwidth)
      
    <<TablelistThemeDefaultsChanged>> to update
    the appearance of your Tk widgets according to the new values contained in
    the array tablelist::themeDefaults, by binding to the
    dedicated binding tag TablelistMain associated with the
    main window:bind TablelistMain <<TablelistThemeDefaultsChanged>> ...
TablelistMain is assigned by
    Tablelist_tile to the main window and used internally for handling the
    virtual events <<ThemeChanged>>,
    <<LightAqua>>, and
    <<DarkAqua>>.  As shown above,
    applications can make use of it, e.g., to handle the virtual event
    <<TablelistThemeDefaultsChanged>>.
