Focus management is really scattered across the codebase. There's sort of a battle between different code paths to make the focus the correct desired state. It seemed to grow like a knot and once I started pulling on one thread to see if it was still needed you could see underneath that it was accounting for another thing underneath that perhaps wasn't needed. The impetus for this PR came but especially during the text label rework, now that it's much more easy to jump around from textfield to textfield. It became apparent that we were playing whack-a-mole trying to preserve the right focus conditions (especially on iOS, ugh). This tries to remove as many hacks as possible, and bring together in place the focus logic (and in the darkness, bind them). ## Places affected - [x] `useEditableText`: was able to remove a bunch of the focus logic here. In addition, it doesn't look like we need to save the selection range anymore. - lingering footgun that needed to be fixed anyway: if there are two labels in the same shape, because we were just checking `editingShapeId === id`, the two text labels would have just fought each other for control - [x] `useFocusEvents`: nixed and refactored — we listen to the store in `FocusManager` and then take care of autoFocus there - [x] `useSafariFocusOutFix`: nixed. not necessary anymore because we're not trying to refocus when blurring in `useEditableText`. original PR for reference: https://github.com/tldraw/brivate/pull/79 - [x] `defaultSideEffects`: moved logic to `FocusManager` - [x] `PointingShape` focus for `startTranslating`, decided to leave this alone actually. - [x] `TldrawUIButton`: it doesn't look like this focus bug fix is needed anymore, original PR for reference: https://github.com/tldraw/tldraw/pull/2630 - [x] `useDocumentEvents`: left alone its manual focus after the Escape key is hit - [x] `FrameHeading`: double focus/select doesn't seem necessary anymore - [x] `useCanvasEvents`: `onPointerDown` focus logic never happened b/c in `Editor.ts` we `clearedMenus` on pointer down - [x] `onTouchStart`: looks like `document.body.click()` is not necessary anymore ## Future Changes - [ ] a11y: work on having an accessebility focus ring - [ ] Page visibility API: (https://developer.mozilla.org/en-US/docs/Web/API/Page_Visibility_API) events when tab is back in focus vs. background, different kind of focus - [ ] Reexamine places we manually dispatch `pointer_down` events to see if they're necessary. - [ ] Minor: get rid of `useContainer` maybe? Is it really necessary to have this hook? you can just do `useEditor` → `editor.getContainer()`, feels superfluous. ## Methodology Looked for places where we do: - `body.click()` - places we do `container.focus()` - places we do `container.blur()` - places we do `editor.updateInstanceState({ isFocused })` - places we do `autofocus` - searched for `document.activeElement` ### Change Type <!-- ❗ Please select a 'Scope' label ❗️ --> - [x] `sdk` — Changes the tldraw SDK - [ ] `dotcom` — Changes the tldraw.com web app - [ ] `docs` — Changes to the documentation, examples, or templates. - [ ] `vs code` — Changes to the vscode plugin - [ ] `internal` — Does not affect user-facing stuff <!-- ❗ Please select a 'Type' label ❗️ --> - [ ] `bugfix` — Bug fix - [ ] `feature` — New feature - [x] `improvement` — Improving existing features - [ ] `chore` — Updating dependencies, other boring stuff - [ ] `galaxy brain` — Architectural changes - [ ] `tests` — Changes to any test code - [ ] `tools` — Changes to infrastructure, CI, internal scripts, debugging tools, etc. - [ ] `dunno` — I don't know ### Test Plan - [x] run test-focus.spec.ts - [x] check MultipleExample - [x] check EditorFocusExample - [x] check autoFocus - [x] check style panel usage and focus events in general - [x] check text editing focus, lots of different devices, mobile/desktop ### Release Notes - Focus: rework and untangle existing focus management logic in the SDK |
