Struct TooltipHover 

pub struct TooltipHover { /* private fields */ }

Hover state for one tooltip.

generation is bumped on every hover transition; a timer that fires after a newer transition has been recorded is stale and must not flip the tip. That is what keeps a fast pass over a row of triggers from opening all of them.

focus_dismissed is what Escape trips for a focus-opened tip. The focus gate (contains_focused && focus_visible) is not something Escape may clear — focus_visible is app-wide state every focus ring reads — so the dismissal is remembered per tooltip instead, and dropped on either edge of the focus session. A dismissal therefore lasts only for the current focus: the next keyboard focus shows the tip again.

Implementations

impl TooltipHover

pub fn closed() -> Self

A closed tip, for a caller that needs the same seed the component uses.

The state lives in Window::use_keyed_state under the tooltip’s id, and a test (or any caller that wants to read the flag) has to hand that call the identical initialiser or it seeds a different slot.

pub fn is_open(&self) -> bool

Whether the tip is currently shown.

pub fn is_focus_open(&self) -> bool

Whether keyboard-visible focus opened the tip in this focus session.
