This property holds the acceleration in the motion of the touch point for this gesture
Access functions:
| qreal | acceleration() const |
| void | setAcceleration(qreal value) |
[read-only] delta : const QPointFThis 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 |
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.
Access functions:
| QPointF | lastOffset() const |
| void | setLastOffset(const QPointF &value) |
This property holds the total offset from the first input position to the current input position
The offset measures the total change in position of the user's input covered by the gesture on the input device.
Access functions:
| QPointF | offset() const |
| void | setOffset(const QPointF &value) |
