class QPanGesture

The QPanGesture class describes a panning gesture made by the user. More…

Added in version 4.6.

Synopsis

Properties

• accelerationᅟ - The acceleration in the motion of the touch point for this gesture

• deltaᅟ - The offset from the previous input position to the current input

• lastOffsetᅟ - The last offset recorded for this gesture

• offsetᅟ - The total offset from the first input position to the current input position

Methods

• def __init__()

• def acceleration()

• def delta()

• def lastOffset()

• def offset()

• def setAcceleration()

• def setLastOffset()

• def setOffset()

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property accelerationᅟ: float

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

Access functions:

• acceleration()

• setAcceleration()

property deltaᅟ: 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:

• delta()

property lastOffsetᅟ: 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:

• lastOffset()

• setLastOffset()

property offsetᅟ: 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:

• offset()

• setOffset()
