# isVertical

An integer indicating the orientation (vertical or horizontal) of the slider.

## Declaration

```swift
var isVertical: Bool { get set }
```

```swift
var vertical: Bool { get set }
```

## Discussion

Discussion The value of this property is 1 if the slider is vertical, 0 if it’s horizontal, and –1 if the orientation can’t be determined (for example, if the slider hasn’t been displayed yet). A slider is defined as vertical if its height is greater than its width.
