Trait Implementations

impl PlotMarks for SankeyMarks

const NAME: &'static str = "SankeyChart"

The widget name.

const LABEL: &'static str = "Sankey diagram"

The accessible name of an untitled chart.

type Hover = Hit

The inspected mark.

type Activated = GraphSelection

What activating a mark reports through Plot::take_activated.

fn frame(&self) -> &PlotFrame<Hit>

fn frame_mut(&mut self) -> &mut PlotFrame<Hit>

fn hit(&self, point: Point) -> Option<Hit>

The mark under point.

fn activation(&self, _: &Hit) -> Option<GraphSelection>

What activating item reports; None when it is not activatable.

fn keyboard_items(&self) -> Vec<Hit>

The marks the keyboard steps through, in order.

fn anchor(&self, _: &Hit) -> Option<Point>

Where inspecting item puts the pointer; None leaves it.

fn items(&self) -> Vec<PlotItem<GraphSelection>>

Every mark the accessibility tree lists.

fn paint( &mut self, scene: &mut Scene, transform: Affine, tr: &mut TextRenderer, theme: &Theme, )

Paints the marks. Call Self::follow_keyboard_anchor once the geometry is current and before painting the inspector.

fn label(&self) -> &'static str

The accessible name, which can depend on the marks’ style.

fn series(&self) -> Vec<(&str, &str)>

The series that can be shown and hidden, as (id, name).

fn legend_interactive(&self) -> bool

Whether clicking a legend entry shows or hides its series.

fn toggles(&self) -> Option<&SeriesToggles>

fn toggles_mut(&mut self) -> Option<&mut SeriesToggles>

fn series_of(&self, _item: &Self::Hover) -> Option<&str>

The series item belongs to, if any.

fn is_animating(&self) -> bool

fn layout_height(&self) -> Option<f32>

The height the chart lays out at; None fills the parent.

fn natural_height( &self, _tr: &mut TextRenderer, _theme: &Theme, _width: f64, ) -> f64

The height a filling chart wants at width when the parent leaves it open.

fn event(&mut self, _event: &WindowEvent, _ctx: &mut EventCtx<'_>) -> bool

Takes the events the shell’s own inspection cannot drive — zoom, pan, brush, focus loss — before the shell inspects. Whether the event was consumed.

fn wants_pointer_capture(&self) -> bool

Whether a gesture is in flight and must keep receiving the pointer.

fn visible_changed(&mut self)

A series was shown or hidden: marks that cache their domain or their geometry drop it.

fn follow_keyboard_anchor(&mut self)

Keeps the pointer on a mark the keyboard chose while the geometry changes under it, so its inspector shows there.
