Struct LayoutNode 

pub struct LayoutNode<T: LayoutTreeNode> { /* private fields */ }

The layout information of a tree node.

Implementations

impl<T: LayoutTreeNode> LayoutNode<T>

pub fn new() -> Self

Create a new layout node.

pub fn mark_dirty(&self, node: &T::TreeVisitor) -> bool

Informs the node styles been changed.

pub fn result(&self) -> Rect<T::Length>

Get the size and position results (border rect).

pub fn result_padding_rect(&self) -> Rect<T::Length>

Get the result padding rect.

pub fn result_content_rect(&self) -> Rect<T::Length>

Get the result content rect.

pub fn computed_style(&self) -> ComputedStyle<T::Length>

Get the computed styles, such as margins, borders, and paddings.

pub fn update( &self, env: &mut T::Env, node: &T, available_size: OptionSize<T::Length>, )

Check all nodes that has been mark_dirty, and update the layout results of the whole tree.

Should only be called on the tree root node. The env will be received in measure functions.

pub fn update_with_containing_size( &self, env: &mut T::Env, node: &T, available_size: OptionSize<T::Length>, containing_size: OptionSize<T::Length>, )

Check all nodes that has been mark_dirty, and update the layout results of the whole tree with container size given.

Should only be called on the tree root node. The env will be received in measure functions. available_size is the available size for the root node. containing_size is the size of the viewport.
