void makVrv::DtObserverEventProcessor::getHiddenMousePosition	(	int &	mouseX,
		int &	mouseY
	)

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

Returns the name of the processor class, to be used for identifying an event processor.

Implements makVrv::DtEventProcessorInterface.

void makVrv::DtObserverEventProcessor::processRightClickOnSelection	(	DtChannel &	channel,
		const DtUniqueID &	objectId,
		const DtMouseState &	mouseState
	)

Process a mouse right click on selection event.

static bool makVrv::DtObserverEventProcessor::isJumpToEvent	(	DtMouseEvent::EventType	mouseEventType,
