The QSwipeGesture class describes a swipe gesture made by the user.
See also Gestures Programming, QPanGesture, and QPinchGesture.
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. |
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:
| SwipeDirection | horizontalDirection () const |
See also verticalDirection and swipeAngle.
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.
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:
| SwipeDirection | verticalDirection () const |
