# rangeChanged

A single-bit Boolean that indicates whether the range variable changed since the last event was dispatched.

```
uint32_t rangeChanged;
```

## Discussion

For example, this property is `1` if the value in the [`inRange`](/documentation/HIDDriverKit/IOHIDDigitizerTouchData/inRange) field changed from `0` to `1` since the last event.
