Struct SelectionRegionController 

pub struct SelectionRegionController { /* private fields */ }

Stable handle used to inspect or update a selection region’s retained state.

Implementations

impl SelectionRegionController

pub const fn new(id: WidgetId) -> Self

pub const fn id(self) -> WidgetId

pub fn selection(self, state: &RuntimeState) -> Option<TextRegionSelection>

Reads the retained selection, for example from ViewHandle::runtime() during a declarative build.

pub fn apply( self, state: &mut RuntimeState, ir: &CoreIR, command: SelectionRegionCommand, ) -> Result<(), SelectionRegionError>

Applies a selection command to the current lowered tree.

pub fn select_scalar_range( self, state: &mut RuntimeState, ir: &CoreIR, base: usize, extent: usize, affinity: TextAffinity, ) -> Result<(), SelectionRegionError>

Selects a range expressed in Unicode scalar offsets into the region’s combined accessibility value.
