fn node_classes(&mut self) -> &mut NodeClassSet

Mutable reference to the NodeClassSet.

fn nodes(&self) -> Iter<'_, (AccessibilityId, Node)>

Iterator over the Accessibility Tree of Nodes.

fn focus_id(&self) -> Option<AccessibilityId>

Get the currently focused Node’s ID.

fn set_focus(&mut self, new_focus_id: Option<AccessibilityId>)

Provided Methods

fn add_node( &mut self, dioxus_node: &DioxusNode<'_>, node_areas: &NodeAreas, accessibility_id: AccessibilityId, node_accessibility: &AccessibilityState )

Add a Node to the Accessibility Tree.

fn set_focus_with_update( &mut self, new_focus_id: Option<AccessibilityId> ) -> Option<TreeUpdate>
