Implemented on the root of the widget tree
Represents the root of a widget tree and being a starting point for widget resolving

Required methods

fn widget(&self, i: E::WidgetPath) -> Result<Resolved<'_, E>, GuionError<E>>[src]

Resolve Widget by path

IMPL Implementations often can just call resolve_in_root

fn widget_mut(
    &mut self,
    i: E::WidgetPath
) -> Result<ResolvedMut<'_, E>, GuionError<E>>[src]

Resolve Widget by path

IMPL Implementations often can just call resolve_in_root_mut

fn trace_bounds(
    &self,
    ctx: &mut E::Context,
    i: E::WidgetPath,
    b: &Bounds,
    e: &EStyle<E>,
