| qreal | acceleration () const |
| void | setAcceleration ( qreal value ) |
delta : const QPointF
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 |
lastOffset : QPointF
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 ) |
offset : QPointF
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 ) |
