Tooltip Requirements

Anatomy:

<Tooltip.Root delayDuration={800} gutter={4} flip placement="top">
  <Tooltip.Trigger>
    <button>Hover or Focus me</button>
  </Tooltip.Trigger>
  <Tooltip.Panel aria-label="Tooltip content">
    <Tooltip.Arrow width={10} height={5} />
    Tooltip content here
  </Tooltip.Panel>
</Tooltip.Root>

Features:

Critical:

  • Opens on hover or focus
  • Closes on trigger activation or Escape key press
  • Customizable open/close delays
  • Optional arrow component
  • Always portaled content
  • Accessibility with ARIA roles and keyboard interactions
  • Flipping to avoid overflow
  • Automatic placement adjustment

Advanced:

  • Custom animations
  • Theming support

Props:

Root:

  • open: boolean - The controlled open state of the tooltip.
  • bind:open: boolean - Reactive state of the tooltip.
  • onOpenChange$: function - Callback when the open state changes.
  • delayDuration: number - Delay before the tooltip opens.
  • gutter: number - Space between the trigger and the tooltip.
  • flip: boolean - Enable flipping to avoid overflow.
  • placement: "top" | "bottom" | "left" | "right" - The default position of the tooltip.

Trigger:

  • Data Attributes:
    • data-state: "closed" | "delayed-open" | "instant-open"

Panel:

  • aria-label: string - ARIA label for accessibility.
  • onEscapeKeyDown$: function - Function to handle Escape key press.
  • onPointerDownOutside$: function - Function to handle pointer down events outside the tooltip.
  • sticky: "partial" | "always" - Whether the tooltip should remain open when interacting with content inside.

Arrow:

  • width: number - The width of the arrow.
  • height: number - The height of the arrow.

Keyboard Interactions:

  • Down Arrow:
    • Opens the tooltip.
  • Up Arrow:
    • Moves focus to the previous focusable element.

ARIA Roles, States, and Properties for Tooltip

  1. Tooltip Element:

    • role="tooltip": Applied to the tooltip container element.
  2. Trigger Element:

    • aria-describedby: References the tooltip element's ID.
  3. Focus Management:

    • Tooltip does not receive focus. Focus remains on the owning element.
      Escape: Closes the tooltip.
  4. Interaction:

    • Tooltip appears on hover or focus.
    • Closes automatically on mouse out or when focus is lost.
    • Stays open when hovered.

Example Usage:

import { component$ } from '@builder.io/qwik';
import { Tooltip } from '@qwik-ui/headless';

export const App = component$(() => {
  return (
    <Tooltip.Root defaultOpen={false} delayDuration={800} gutter={4} flip placement="top" autoPlacement>
      <Tooltip.Trigger>
        <button>Hover or Focus me</button>
      </Tooltip.Trigger>
      <Tooltip.Panel aria-label="Tooltip content">
        <Tooltip.Arrow width={10} height={5} />
        Tooltip content here
      </Tooltip.Panel>
    </Tooltip.Root>
  );
});

This comprehensive guide provides detailed information on the anatomy, features, props, and usage of the Tooltip component in Qwik, ensuring a consistent and accessible implementation.

Existing Tooltip Libraries Comparison

To determine a basic feature set for the tooltip component, I compared the tooltop components from Melt, Kobalte, and Radix. I'll start with the common features they all share. You can read about them more individually below.
