Struct floem::context::LayoutCx

pub struct LayoutCx<'a> { /* private fields */ }

Holds current layout state for given position in the tree. You’ll use this in the View::layout implementation to call layout_node on children and to access any font

Implementations

impl<'a> LayoutCx<'a>

pub fn app_state_mut(&mut self) -> &mut AppState

pub fn app_state(&self) -> &AppState

pub fn get_computed_style(&mut self, id: Id) -> &Style

pub fn set_style(&mut self, node: Node, style: Style)

pub fn new_node(&mut self) -> Node

pub fn layout_node( &mut self, id: Id, has_children: bool, children: impl FnMut(&mut LayoutCx<'_>) -> Vec<Node> ) -> Node

Responsible for invoking the recalculation of style and thus the layout and creating or updating the layout of child nodes within the closure.

You should ensure that all children are laid out within the closure and/or whatever other work you need to do to ensure that the layout for the returned nodes is correct.

pub fn layout_view(&mut self, view: &mut dyn View) -> Node

Internal method used by Floem to invoke the user-defined View::layout method.
