### setCamera

```python
setCamera(camera: str | None = None, force: bool = False) -> None
```

Set which camera this widget tracks.

Using this on the `DefaultCameraExposureWidget`widget may cause unexpected behavior, instead try to use an `ExposureWidget`.

Parameters:

| Name | Type | Description | Default |
| --- | --- | --- | --- |
| `camera` | `str` | The camera device label. By default, None. If not specified, the widget will use the current Camera device. | `None` |
| `force` | `bool` | Whether to force a change away from tracking the default camera. | `False` |
