There was a problem hiding this comment.
The backward compatibility logic has a conflict when both disableAutoFocus and focusOnHover are provided. If a user provides disableAutoFocus={false} and focusOnHover={false}, the resolved value will be true (unexpected behavior).
// Current:
const resolvedFocusOnHover =
disableAutoFocus !== undefined ? !disableAutoFocus : focusOnHover
// Fix: Warn or handle both being set
const resolvedFocusOnHover = (() => {
if (disableAutoFocus !== undefined && focusOnHover !== true) {
console.warn('Both disableAutoFocus and focusOnHover are set. Using focusOnHover. disableAutoFocus is deprecated.')
return focusOnHover
}
return disableAutoFocus !== undefined ? !disableAutoFocus : focusOnHover
})()Alternatively, only check disableAutoFocus if focusOnHover was not explicitly set by checking if it differs from the default.

Pull request overview
This PR aims to replace the double-negative disableAutoFocus API with a clearer focusOnHover boolean toggle on the PCB viewer components, including adding Storybook coverage for the new prop.
Changes:
- Added a new Storybook story to demonstrate
focusOnHoverenabled/disabled. - Refactored
PCBViewerto delegate rendering to a newInteractiveGraphicscomponent. - Added deprecated
disableAutoFocussupport intended to map tofocusOnHover.

Unused imports (useEffect, useRef, useState) and unused destructured prop (children) will fail Biome linting in this repo. Remove them or use children in the render output.

This file imports ./edit-events and ./PCBRender, but those modules do not exist in the repository (and there are no other EditEvent / PCBRender definitions). This will cause immediate build/typecheck failures; add the missing files/exports or update the imports to point at existing types/components.

There are multiple unused imports (useEffect, useState, SuperGrid, useMouseMatrixTransform), which will fail Biome's recommended lint rules. Remove them; if you intended to use use-mouse-matrix-transform, note that the rest of the codebase imports it as a default export, not a named export.

tabIndex={0} on a non-interactive <div> and style={{ outline: "none" }} will likely trigger Biome a11y linting and also removes visible focus indication for keyboard users. Consider adding a biome-ignore lint/a11y/noNoninteractiveTabindex with an explanation (as done elsewhere), and provide an accessible focus style (e.g. :focus-visible) instead of removing the outline entirely.

PCBViewerProps dropped several previously supported props (e.g. height, debugGraphics, initialState, disablePcbGroups, clickToInteractEnabled). The repo still has many call sites using these (e.g. src/examples/2025/disable-pcb-groups.fixture.tsx, src/examples/2025/features/click-to-enable-zoom.fixture.tsx), so this change will break type-checking/build and is a public API breaking change. Either keep these props and pass them through to the new implementation, or introduce a separate component for the simplified API while keeping PCBViewer backward-compatible.

The deprecated disableAutoFocus mapping overrides focusOnHover even when disableAutoFocus={false} is passed, which can flip an explicitly provided focusOnHover={false} to true. Consider only overriding when disableAutoFocus === true, otherwise fall back to focusOnHover.

Fixes #163
What changed
focusOnHoverprop (defaults totrue) toPCBViewerandInteractiveGraphics.focusOnHover={false}replaces the olddisableAutoFocus={true}behavior.disableAutoFocusas@deprecatedwith backward-compatible support (it still works but maps to!focusOnHoverinternally).focusOnHover={true}(default) andfocusOnHover={false}.Why
The
disableAutoFocusname is a double-negative and non-idiomatic.focusOnHoverclearly describes the feature as a toggle, making the API easier to read and reason about.
