Constructor & Destructor Documentation

mitk::MoveSurfaceInteractor::MoveSurfaceInteractor	(	const char *	type,
		DataNode *	dataNode
	)		[protected]

check how good an event can be handled

Gets called when mitk::DataNode::SetData() is called

No need to use it here, because the pattern won't be complex and we can take care of unexpected data change Constructor

Examples:

mitkMoveSurfaceInteractor.cpp.

:Interactor(type, dataNode)
{
}

mitk::MoveSurfaceInteractor::~MoveSurfaceInteractor

(

[protected, virtual]

Default Destructor.
