Struct HoverCard 

pub struct HoverCard { /* private fields */ }

A preview surface that opens on hover and can be pointed at.

Implementations

impl HoverCard

pub fn new( ident: impl Into<Ident>, _window: &mut Window, cx: &mut Context<'_, Self>, ) -> Self

pub fn trigger( self, trigger: impl Fn(&mut Window, &mut App) -> AnyElement + 'static, ) -> Self

Supplies what is hovered, rebuilt on every frame.

pub fn name(self, name: impl Into<SharedString>) -> Self

Names the trigger. A preview hanging off a picture or an avatar has no words of its own, and a control nobody can name is one nobody can reach.

pub fn content( self, content: impl Fn(&mut Window, &mut App) -> AnyElement + 'static, ) -> Self

Supplies the card body, rebuilt on every frame the card is open.

pub fn placement(self, placement: Placement) -> Self

pub fn open_delay(self, delay: Duration) -> Self

How long the pointer rests before the card opens. Zero opens at once.

pub fn grace(self, grace: Duration) -> Self

How long the card survives the pointer being over neither surface.

pub fn is_open(&self) -> bool

pub fn is_leaving(&self) -> bool

True while the card is on screen with the pointer over neither surface, which is the window during which the trip can still be completed.

pub fn grace_period(&self) -> Duration

pub fn open(&mut self, cx: &mut Context<'_, Self>)

pub fn close(&mut self, cx: &mut Context<'_, Self>)

Closes the card without giving the keyboard back, which is what a pointer leaving should do: the keyboard was never here.

pub fn dismiss(&mut self, window: &mut Window, cx: &mut Context<'_, Self>)

Closes and hands the keyboard back to the trigger, which is what escape should do.
