Struct HeadlessApp 

pub struct HeadlessApp {
    pub tree: WidgetTree,
    pub theme: Theme,
    pub i18n_manager: Option<Rc<I18nManager>>,
    pub settings: Option<OpenedSettings>,
}

A headless app for testing (no window, no GPU).

Fields

tree: WidgetTree

theme: Theme

i18n_manager: Option<Rc<I18nManager>>

Active i18n manager, if TeksiloAppBuilder::i18n(...) was used. Tests can reach the bundles, version signal, and locale signal directly through this handle.

settings: Option<OpenedSettings>

Active persistence services, if TeksiloAppBuilder::settings(...) was used. Held here so the underlying SettingsFile clones (and their I/O threads) live as long as the headless app.

Implementations

impl HeadlessApp

pub fn theme(&self) -> &Theme

pub fn i18n_manager(&self) -> Option<&Rc<I18nManager>>

The active i18n manager, if i18n(...) was registered on the builder.

pub fn set_locale(&mut self, locale: LanguageIdentifier)

Switch the active locale. Updates the manager (which increments the version signal so any LocalizedString::to_signal() observers re-resolve), then seeds the tree with the new direction (only when it actually changed) and triggers a composite rebuild via WidgetTree::set_locale. No-op if no I18nConfig was registered.
