Struct Remount 

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

The retained layout tree a Widget::remount_children changes, and what the change mounted and unmounted, for the host to admit.

Implementations

impl<'a> Remount<'a>

pub fn taffy(&mut self) -> &mut TaffyTree

The tree, to read a node’s layout or set a style.

pub fn theme(&self) -> &'a Theme

The theme the tree is laid out with.

pub fn mount(&mut self, owner: NodeId, child: &mut dyn Widget) -> NodeId

Build child’s layout into the tree, for the widget remounting, whose node is owner, to place under its own nodes through Self::set_children. Returns its node.

pub fn mount_with( &mut self, owner: NodeId, build: impl FnOnce(&mut TaffyTree, &Theme, &mut HashMap<NodeId, *mut dyn Widget>) -> Option<NodeId>, ) -> Option<NodeId>

Self::mount for a widget that builds what it places under owner itself (build, with the tree, the theme and the node map, as Widget::build_layout has them): the node it returns is mounted; None mounts nothing.

pub fn unmount(&mut self, node: NodeId)

Remove node, a child the widget remounting lets go of, and everything under it from the tree and the node map. Its widgets stay alive: the widget keeps them to mount again.

pub fn set_children( &mut self, parent: NodeId, children: &[NodeId], ) -> Result<(), TaffyError>

Make children the children of parent, in order.

Errors

Taffy’s, when a node is not in the tree.
