## Member Type Documentation

### enum QSwipeGesture::SwipeDirection

This enum describes the possible directions for the gesture's motion along the horizontal and vertical axes.

Constant | Value | Description
--- | --- | ---
`QSwipeGesture::NoDirection` | `0` | The gesture had no motion associated with it on a particular axis.
`QSwipeGesture::Left` | `1` | The gesture involved a horizontal motion to the left.
`QSwipeGesture::Right` | `2` | The gesture involved a horizontal motion to the right.
`QSwipeGesture::Up` | `3` | The gesture involved an upward vertical motion.
`QSwipeGesture::Down` | `4` | The gesture involved a downward vertical motion.

## Property Documentation

### `[read-only]` horizontalDirection : const SwipeDirection

This property holds the horizontal direction of the gesture

If the gesture has a horizontal component, the horizontal direction is either Left or Right; otherwise, it is NoDirection.

Access functions:

QSwipeGesture::SwipeDirection | horizontalDirection() const

See also verticalDirection and swipeAngle.

### swipeAngle : qreal

This property holds the angle of the motion associated with the gesture

If the gesture has either a horizontal or vertical component, the swipe angle describes the angle between the direction of motion and the x-axis as defined using the standard widget coordinate system.

Access functions:

qreal | swipeAngle() const
void | setSwipeAngle(qreal value)

See also horizontalDirection and verticalDirection.

### `[read-only]` verticalDirection : const SwipeDirection

This property holds the vertical direction of the gesture

If the gesture has a vertical component, the vertical direction is either Up or Down; otherwise, it is NoDirection.

Access functions:

QSwipeGesture::SwipeDirection | verticalDirection() const

See also horizontalDirection and swipeAngle.
