HoverCard view

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

A view survives a frame. Hold it in an Entity with cx.new(..) and reach it with .update(..).

use gpui_kit::overlay::HoverCard;

Construct

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

Options

Chain onto the value.

trigger(trigger: impl Fn(&mut Window, &mut App) -> AnyElement + 'static) -> Self
name(name: impl Into<SharedString>) -> Self
content(content: impl Fn(&mut Window, &mut App) -> AnyElement + 'static) -> Self
placement(placement: Placement) -> Self
open_delay(delay: Duration) -> Self
grace(grace: Duration) -> Self

Commands

Need a Context, so they need a view.

open(cx: &mut Context<Self>)
close(cx: &mut Context<Self>)
dismiss(window: &mut Window, cx: &mut Context<Self>)

Queries

Only answer; they change nothing.

is_open() -> bool
is_leaving() -> bool
grace_period() -> Duration

Reports

The variants of the event it emits. It never applies the change itself.
