Struct LayoutContext

#[non_exhaustive]
pub struct LayoutContext<'dom> {
    pub dom: &'dom Dom,
    pub input: &'dom InputState,
    pub layout: &'dom mut LayoutDom,
}

Information available to a widget during the layout phase.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

dom: &'dom Dom

input: &'dom InputState

layout: &'dom mut LayoutDom

Implementations

impl<'dom> LayoutContext<'dom>

pub fn calculate_layout( &mut self, widget: WidgetId, constraints: Constraints, ) -> Vec2

Calculate the layout for the given widget with the given constraints.

This method currently must only be called once per widget per layout phase.
