Trait FocusManagerQuery 

pub trait FocusManagerQuery {
    // Required method
    fn get_focused_node_id(&self) -> Option<DomNodeId>;

    // Provided method
    fn get_focused_node_for_seat(&self, seat_id: u64) -> Option<DomNodeId> { ... }
}

Trait for querying focus manager state.

This allows pre_callback_filter_internal_events to query manager state without depending on the concrete FocusManager type from layout crate.

Required Methods

fn get_focused_node_id(&self) -> Option<DomNodeId>

Get the currently focused node ID

Provided Methods

fn get_focused_node_for_seat(&self, seat_id: u64) -> Option<DomNodeId>

The node seat seat_id focuses (9b-ii-a-i-d). A manager without per-seat focus answers the shared one for every seat.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
