TooltipHost

gpui_cn

Struct TooltipHost 

Source 
pub struct TooltipHost { /* private fields */ }
Expand description

The per-window registry of tooltip overlays.

gpui-cn registers the overlay it adds to each Root here. A host with its own root view registers the overlay it owns the same way, and gpui-cn components then show their tooltips through it. With no registration a component falls back to GPUI’s native tooltip.

Implementations§

Source§

impl TooltipHost

Source

pub fn register(window: &Window, overlay: &Entity<TooltipOverlay>, cx: &mut App)

Registers overlay as the tooltip overlay of window.

The registry holds a weak handle, so dropping the overlay (closing the window, replacing the root) unregisters it.

Source

pub fn overlay(window: &Window, cx: &App) -> Option<Entity<TooltipOverlay>>

The tooltip overlay registered for window, if it is still alive.
