virtual void makVrv::DtObserverEventProcessor::getHiddenMousePosition	(	int &	mouseX,

	)

virtual

in the case where the mouse is hidden (because it's being warped to the center of the screen during a drag operation) get the location of the mouse when the operation was initiated (and where the mouse will warp back to on completion).

This is only valid when isViewDragging() or isMouseLooking() is true.

virtual bool makVrv::DtObserverEventProcessor::processMouseEvent	(	const DtMouseEvent &	ev,
		DtChannel &	channel
	)

virtual

Processes a mouse event on the channel.

Should return true if the event is handled successfully, and false to reject it and pass it on to the next event processor.

Implements makVrv::DtEventProcessorInterface.

virtual bool makVrv::DtObserverEventProcessor::processKeyboardEvent	(	const DtKeyEvent &	ev,
		DtChannel &	channel
	)

virtual

Processes a keyboard event on the channel.

Should return true if the event is handled successfully, and false to reject it and pass it on to the next event processor.

Implements makVrv::DtEventProcessorInterface.

virtual bool makVrv::DtObserverEventProcessor::processPinchGesture	(	const DtPinchGesture &	ev,
		DtChannel &	channel
	)

virtual

Processes a pinch gesture event on the channel.

Should return true if the event should be consumed, and false to reject it and pass it on to the next event processor.

Reimplemented from makVrv::DtEventProcessorInterface.

virtual const std::string& makVrv::DtObserverEventProcessor::className ( )
