Struct Tooltip 

pub struct Tooltip { /* private fields */ }

A hover-triggered tooltip attached to a Response.

Construct with the body text and optionally layer on a heading or a keyboard-shortcut row, then call Tooltip::show immediately after rendering the trigger.

Implementations

impl Tooltip

pub fn new(body: impl Into<WidgetText>) -> Self

Create a tooltip with the given body text.

Defaults: anchored above the trigger, no heading, no shortcut row, arrow on, ~8 pt gap between trigger and tooltip.

pub fn heading(self, heading: impl Into<WidgetText>) -> Self

Add a bold heading line above the body.

pub fn shortcut(self, shortcut: impl Into<String>) -> Self

Add a keyboard-shortcut row at the bottom of the tooltip.

The string is split on whitespace and each token is rendered as a small monospace chip, so "\u{2318} S" renders as two chips.

pub fn shortcut_label(self, label: impl Into<String>) -> Self

Override the leading label on the shortcut row. Default: "Shortcut".

pub fn side(self, side: TooltipSide) -> Self

Which side of the trigger to anchor on. Default: TooltipSide::Top.

pub fn width(self, w: f32) -> Self

Fix the tooltip’s max content width, in points. Long body text wraps at this width. Default: 260.

pub fn arrow(self, arrow: bool) -> Self

Toggle the small arrow that points at the trigger. Default: on.

pub fn gap(self, gap: f32) -> Self

Gap between the trigger and the tooltip, in points. Default: 8.

pub fn show(self, trigger: &Response) -> Option<Response>

Render the tooltip attached to trigger. Returns Some(response) while the tooltip is visible, None otherwise.
