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

public void onClick(float x,
           float y)

onDoubleClick

public void onDoubleClick(float x,
                 float y)
