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 preferred_tab_stop(self, preferred: bool) -> Modifier

Prefers this focus target when Tab enters a group with a single Tab stop, preserving its other focus properties.

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.

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

where F: Into<CallbackWith<PxRect>>,

Registers a callback invoked with this node’s window rectangle after attachment and whenever the rectangle changes.

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

where F: Into<CallbackWith<FloatRect>>,

Observes this node’s exact fractional rectangle in window coordinates.

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

where F: Into<CallbackWith<LocalToWindow>>,

Observes the transformation from this node’s local units to the window.

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

where F: Into<CallbackWith<LayoutCoordinates>>,

Observes local layout dimensions and their exact transformation to the window.

Dyn Compatibility

This trait is not dyn compatible.

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