Struct PlotHover 

pub struct PlotHover { /* private fields */ }

The datum a plot has under the pointer this frame, handed to Plot::hover.

Carries the TooltipState the cursor resolved to and how far the hover has faded in. After the cursor leaves, the state lingers here while the progress eases back to zero, so a hover-driven presentation can fade out over the last datum instead of vanishing.

Implementations

impl PlotHover

pub fn state(&self) -> &TooltipState

The hovered datum: the one under the cursor, or the last one while the hover fades out.

pub fn progress(&self) -> f32

How far the hover has faded in, from 0 to 1.

Rises over the active PlotMotion’s enter when the cursor lands on a datum and falls back over its exit after it leaves, during which Self::is_hovered is false.

pub fn focus(&self) -> f32

👎Deprecated since 0.7.0:

use progress

pub fn is_hovered(&self) -> bool

Whether the cursor is on the datum, as opposed to the state lingering while its hover fades out.

pub fn is_entering(&self) -> bool

Whether this is the first frame the cursor is on a datum: the hover has not started fading in yet. A position that follows the hovered datum adopts it here instead of travelling from where the last hover ended.

pub fn glide( &self, id: impl Into<TransitionId>, target: Pixels, window: &mut Window, cx: &mut App, ) -> Pixels

Follow target on the pointer spring, adopting the target on the entering frame instead of travelling from where the last hover ended.

For a position a plot paints with, such as the center of a highlighted band or the crosshair a styled tooltip draws.

Trait Implementations

impl Clone for PlotHover

fn clone(&self) -> PlotHover

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
