### Events

Custom elements put the payload in `detail`; Vue emits an event of the same name.

| Event | Payload |
| --- | --- |
| `files-change` | `FileUploadFilesChangeDetails` |
| `clear` | `` |
| `remote-files-change` | `FileUploadRemoteFilesChangeDetails` |

| Vue component | Slot | Payload |
| --- | --- | --- |
| `XhFileUploadRoot` | `default` | `FileUploadRootSlotProps` |
| `XhFileUploadRoot` | `label` | — |
| `XhFileUploadRoot` | `dropzone` | — |

### React adapter props

Only the props each component declares itself: DOM attributes inherited from `ComponentPropsWithRef` are left out, and root props already listed in the Props table are not repeated. The Vue counterpart is the slot table above.

| React component | Prop | Type | Required |
| --- | --- | --- | --- |
| `XhFileUploadItem` | `file` | `FileUploadFile` |  |
| `XhFileUploadItem` | `index` | `number \| string` |  |
| `XhFileUploadRoot` | `label` | `ReactNode` |  |
| `XhFileUploadRoot` | `dropzone` | `ReactNode` |  |
| `XhFileUploadRoot` | `clearable` | `boolean` |  |
| `XhFileUploadRoot` | `children` | `SlotChildren<FileUploadRootSlotProps>` |  |

### State

Public state is written to `data-state`.

| Part | Values |
| --- | --- |
| `item` | uploadOf(file)?.status |
| `item-progress` | upload?.status |

The following names are internal to the state machine.

**States**: `idle` · `dragging`

**Events**: `FILES.SET` · `FILES.ADD` · `FILE.DELETE` · `FILES.CLEAR` · `PICKER.OPEN` · `DRAG.OVER` · `DRAG.LEAVE` · `DROP` · `PASTE` · `UPLOAD.CANCEL` · `UPLOAD.START` · `REMOTE.DELETE` · `FORM.RESET` · `PRESS.START` · `PRESS.END` · `LIST.TRACKED` · `PROGRESS.SETTLED`

**Guards**: `canChange` · `canTransfer` · `canDrop` · `canPaste`

## Accessibility

### Keyboard

Specification: [W3C APG](https://www.w3.org/WAI/ARIA/apg/patterns/button/#keyboardinteraction). Each row is a stable behavior id that the conformance tests cover; the conditions and effects are described on the Chinese page.

| Keys | Behavior |
| --- | --- |
| `Tab` / `Shift+Tab` | `file-upload.kbd.tab` |
| `Enter` / `Space` | `file-upload.kbd.open-dropzone` |
| `Enter` / `Space` | `file-upload.kbd.open-trigger` |
| `Enter` / `Space` | `file-upload.kbd.delete` |
| `Enter` / `Space` | `file-upload.kbd.clear` |
| `Ctrl+V` / `Meta+V` | `file-upload.kbd.paste` |
| `Enter` / `Space` | `file-upload.kbd.press` |

### ARIA

These attributes are produced by `connect`.

| Part | Attribute | Value |
| --- | --- | --- |
| `dropzone` | `aria-disabled` | 'false' \| 'true' |
| `dropzone` | `aria-invalid` | 'true' \| 'false' |
| `dropzone` | `aria-label` | undefined \| props.ariaLabel |
| `dropzone` | `aria-labelledby` | id of the `label` part id of the `dropzone` part \| id of the `dropzone` part |
| `dropzone` | `role` | 'button' |
| `trigger` | `aria-disabled` | 'true' \| undefined |
| `hidden-input` | `aria-labelledby` | id of the `label` part id of the `dropzone` part \| id of the `dropzone` part |
| `list` | `role` | 'list' |
| `item` | `role` | 'listitem' |
| `item-link` | `aria-disabled` | 'true' \| undefined |
| `item-preview` | `aria-hidden` | 'true' |
| `item-progress` | `aria-hidden` | 'true' |
| `item-delete-trigger` | `aria-disabled` | 'true' \| undefined |
| `item-delete-trigger` | `aria-label` | label.deleteItem(file) |
| `clear-trigger` | `aria-disabled` | 'true' \| undefined |
| `clear-trigger` | `aria-label` | label.clearTrigger |

## Style reference

### Skin

`@xihan-ui/styles/file-upload.css` is written against `[data-scope="file-upload"][data-part="root"]` part selectors; the published build uses the mount class `.xh-scope-file-upload` in place of data-scope (same specificity) and sits in the `xihan.components` layer. Put overrides in `xihan.overrides`; the part selectors work as usual.

### Data attributes

Produced by `connect`; valueless attributes are omitted while their condition does not hold.
