Member Function Documentation

onDragEvent()

EventResult luciad::PanEventHandler::onDragEvent	(	const std::shared_ptr< DragEvent > &	dragEvent,
		const std::shared_ptr< Map > &	map
	)

Moves the map's camera following the drag direction.

The drag event is consumed only if the sequence of events is the following : a EventStatus::Start event, 0 or more EventStatus::InProgress event and finally a EventStatus::End event. If the sequence is not correct, this method returns EventResult::NotConsumed.

Parameters

dragEvent	a drag event. Cannot be nullptr.
map	the map. Cannot be nullptr.

Returns

whether the drag event was consumed or not.

Exceptions

luciad::NullArgumentException

when passing nullptr for the map or the event.
