Property Documentation

QPanGesture::acceleration

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

Properties	Class Methods
read	acceleration
write	setAcceleration

QPanGesture::delta

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().

Properties	Class Methods
read	delta
stored	true

QPanGesture::lastOffset

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.

Properties	Class Methods
read	lastOffset
write	setLastOffset

QPanGesture::offset

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.

Properties	Class Methods
read	offset
write	setOffset
