Struct SemanticsUpdate 

pub struct SemanticsUpdate {
    pub nodes: Vec<(NodeId, Node)>,
    pub root: NodeId,
    pub focus: Option<NodeId>,
}

A collected accessibility tree from RenderRoot::semantics.

Fields

nodes: Vec<(NodeId, Node)>

The flat node map in collection order: each container follows its children (post-order), so the root window node comes last.

root: NodeId

The window node, present even for an empty tree.

focus: Option<NodeId>

The node a widget claimed with SemanticsCtx::set_focused, if any.

Implementations

impl SemanticsUpdate

pub fn focus_id(&self) -> NodeId

The focus to hand an adapter: focus, else root, since accesskit’s TreeUpdate::focus is not optional.
