Struct ReorderController 

pub struct ReorderController<K> { /* private fields */ }

Gesture controller shared by list and tree widgets. Widgets retain model mutation authority and supply their own hit-tested, validated candidates.

Implementations

impl<K> ReorderController<K>

pub fn new() -> ReorderController<K>

pub fn with_drag_threshold(self, logical_pixels: f64) -> ReorderController<K>

pub fn with_edge_scroll(self, zone: f64, max_speed: f64) -> ReorderController<K>

pub fn with_hover_expand_delay(self, delay: Duration) -> ReorderController<K>

pub fn begin(&mut self, source: K, cursor: Point)

pub fn update( &mut self, cursor: Point, candidate: Option<DropCandidate<K>>, now: Instant, validate: impl FnMut(&K, &DropTarget<K>) -> bool, )

where K: PartialEq,

Store a candidate only when validate permits the source/target pair.

pub fn tick( &mut self, viewport: Rect, elapsed: Duration, now: Instant, ) -> ReorderMotion<K>

where K: Clone,

pub fn is_tracking(&self) -> bool

pub fn is_active(&self) -> bool

pub fn source(&self) -> Option<&K>

pub fn target(&self) -> Option<&DropTarget<K>>

pub fn preview(&self) -> Option<Rect>

pub fn cancel(&mut self) -> bool

pub fn finish(&mut self) -> Option<ReorderDrop<K>>
