NoDirection The gesture had no motion associated with it on a particular axis.
Left The gesture involved a horizontal motion to the left.
Right The gesture involved a horizontal motion to the right.
Up The gesture involved an upward vertical motion.
Down The gesture involved a downward vertical motion.

Properties

◆ horizontalDirection

QSwipeGesture::SwipeDirection QSwipeGesture::horizontalDirection

private

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.

See also: verticalDirection, swipeAngle

Definition at line 213 of file qgesture.h.

◆ swipeAngle

qreal QSwipeGesture::swipeAngle

private

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{coordinate system}.

See also: horizontalDirection, verticalDirection

Definition at line 215 of file qgesture.h.

◆ verticalDirection

QSwipeGesture::SwipeDirection QSwipeGesture::verticalDirection

private

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.
