Focus-specific modifier extensions for Modifier.

Required Methods

fn focusable(self) -> Modifier

Registers a focus target for this subtree.

fn focus_requester(self, requester: FocusRequester) -> Modifier

Binds an explicit focus requester to this subtree.

fn focus_properties(self, properties: FocusProperties) -> Modifier

Applies explicit focus properties to this subtree.

fn focus_group(self) -> Modifier

Registers a traversal-only focus group for this subtree.

fn focus_scope_with(self, scope: FocusScopeNode) -> Modifier

Registers an explicit focus scope handle for this subtree.

fn focus_group_with(self, group: FocusGroupNode) -> Modifier

Registers an explicit focus group handle for this subtree.

fn focus_restorer(self, fallback: Option<FocusRequester>) -> Modifier

Registers a focus scope with restore behavior for this subtree.

fn focus_restorer_with( self, scope: FocusScopeNode, fallback: Option<FocusRequester>, ) -> Modifier

Registers an explicit focus restorer scope for this subtree.

fn focus_traversal_policy(self, policy: FocusTraversalPolicy) -> Modifier

Applies a traversal policy to the current focus group or scope.

fn on_focus_changed<F>(self, handler: F) -> Modifier

where F: Into<CallbackWith<FocusState>>,

Registers a callback that runs when the subtree focus state changes.

fn on_focus_event<F>(self, handler: F) -> Modifier

where F: Into<CallbackWith<FocusState>>,

Registers a callback that observes focus events for this subtree.

fn focus_beyond_bounds_handler<F>(self, handler: F) -> Modifier

where F: Into<CallbackWith<FocusDirection, bool>>,

Registers a callback that moves focus beyond the current viewport.

fn focus_reveal_handler<F>(self, handler: F) -> Modifier

where F: Into<CallbackWith<FocusRevealRequest, bool>>,

Registers a callback that reveals the focused target within the viewport.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
