Methods

impl QPanGesture

pub unsafe fn acceleration(&self) -> c_double

This property holds the acceleration in the motion of the touch point for this gesture

Calls C++ function: double QPanGesture::acceleration() const.

C++ documentation:

This property holds the acceleration in the motion of the touch point for this gesture

Access functions:

qreal	acceleration() const
void	setAcceleration(qreal value)

pub unsafe fn delta(&self) -> CppBox<QPointF>

This property holds the offset from the previous input position to the current input

Calls C++ function: QPointF QPanGesture::delta() const.

C++ documentation:

This property holds the offset from the previous input position to the current input

This is essentially the same as the difference between offset() and lastOffset().

Access functions:

QPointF

delta() const

pub unsafe fn last_offset(&self) -> CppBox<QPointF>

This property holds the last offset recorded for this gesture

Calls C++ function: QPointF QPanGesture::lastOffset() const.

This property holds the last offset recorded for this gesture

The last offset contains the change in position of the user's input as reported in the offset property when a previous gesture event was delivered for this gesture.

If no previous event was delivered with information about this gesture (i.e., this gesture object contains information about the first movement in the gesture) then this property contains a zero size.
