Detailed Description

Listener of simple gestures. It is a convenience class to ease simple gestures handling.

Note

A drag event always follows a pinch.

Version

2.0

2.1.19 Renamed from VgISimpleGestureManipulatorListener to VgManipulatorListener.

void VgManipulatorListenerRefPtr.onClick	(	float	x,
		float	y
	)

Callback on a click gesture. This gesture has no state.

Remarks

these are the same parameters for VgICamera::pickGeographicPoint

Parameters

x	normalized screen coordinate. 0.0f is left of screen, 1.0f is right.
y	normalized screen coordinate. 0.0f is top, 1.0f is bottom.

Version

2.0.8002

void VgManipulatorListenerRefPtr.onDoubleClick	(	float	x,
		float	y
	)

Callback on a double click gesture. This gesture has no state.

Remarks

these are the same parameters for VgICamera::pickGeographicPoint

there is no filtering of "onClick" events on a double click event, meaning each onDoubleClick event will be preceded by two onClick events.

Parameters

x	normalized screen coordinate. 0.0f is left of screen, 1.0f is right.
y	normalized screen coordinate. 0.0f is top, 1.0f is bottom.

Version

2.0.8002

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

Callback on a drag gesture.

Remarks

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

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.

void VgManipulatorListenerRefPtr.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.
