onSimplePinch

public void onSimplePinch(VgGestureState pState,
                          float pSpan,
                          float pVelocity)

Callback on a pinch gesture with two fingers.

Parameters:

pState - The state associated with the gesture.

pSpan - Distance in pixels between the two fingers.

pVelocity - Speed in pixels per milliseconds.

onSimpleDrag

public void onSimpleDrag(VgGestureState pState,
                         long pNbTouch,
                         float pAverageXOffset,
                         float pAverageYOffset)

Callback on a drag gesture.

Parameters:

pState - The state associated with the gesture.

pNbTouch - Number of fingers on the touchpad.

pAverageXOffset - Average dragging offset in pixels since previous callback. The offset is computed as an average of each finger's offset.

pAverageYOffset - Average dragging offset in pixels since previous callback. The offset is computed as an average of each finger's offset.

Remark:

This callback handles dragging gestures up to 2 fingers at the same time. With 3 fingers or more, this callback won't be triggered.

onClick

                    float y)

onDoubleClick

public void onDoubleClick(float x,
                          float y)
