Detailed Description

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

Version: 2.0; 2.1.19 Renamed from VgISimpleGestureManipulatorListener to VgManipulatorListener.

Constructor & Destructor Documentation

VgManipulatorListener.VgManipulatorListener ( )

void VgManipulatorListener.onClick	(	float	x,
		float	y
	)

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

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.

void VgManipulatorListener.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.

void VgManipulatorListener.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 VgManipulatorListener.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.
