Struct SharedIconProvider 

pub struct SharedIconProvider { /* private fields */ }

Thread-safe icon provider for use in windows.

This is created from IconProviderHandle::into_shared() in App::run() and cloned to each window.

Implementations

impl SharedIconProvider

pub fn from_handle(handle: IconProviderHandle) -> Self

Create from an IconProviderHandle (consumes the handle)

pub fn register_icon(&self, pack_name: &str, icon_name: &str, data: RefAny)

Register (or REPLACE) one icon on a live shared provider.

The registration path that exists after startup. IconProviderHandle is consumed by Self::from_handle, so a pack built once at App::create could never be refreshed - and it has to be: a pack whose artwork depends on the OS theme (the desktop’s own icons, tinted with the palette) is WRONG the moment the theme flips, and re-reading it is the only way to get the dark variant.

Flushes the resolution cache: entries there hold the Dom the OLD artwork resolved to, and serving those back would make the re-registration invisible.

pub fn resolve( &self, original_icon_node: &NodeData, icon_name: &str, system_style: &SystemStyle, ) -> Dom

Resolve an icon to a StyledDom using the registered callback

pub fn lookup(&self, icon_name: &str) -> Option<RefAny>

Look up an icon by spec (bare name, pack:name, or a comma-separated fallback list of either form; first match wins)

pub fn has_icon(&self, icon_name: &str) -> bool

Check if an icon spec resolves
