Struct ThemeRegistry 

pub struct ThemeRegistry { /* private fields */ }

The set of themes an application can switch between at runtime.

Implementations

impl ThemeRegistry

pub fn global(cx: &App) -> &ThemeRegistry

pub fn new() -> ThemeRegistry

pub fn register(&mut self, tokens: TokenDocument)

Adds or replaces a theme. A registered id replaces the earlier document so an application can override a bundled theme without shadowing it.

pub fn register_json(&mut self, json: &str) -> Result<(), TokenError>

pub fn ids(&self) -> Vec<SharedString>

pub fn active(&self) -> &Theme

pub fn density(&self) -> Density

pub fn activate(&mut self, id: &str) -> bool

Returns false when the id is not registered, leaving the active theme untouched rather than falling back to a default the caller did not ask for.

pub fn set_density(&mut self, density: Density)
