Detailed Description

Event that stores coordinates.

Stores display position of the mouse.

If requested, the correspondent 3D world position in mm is calculated via picking (delegated to the BaseRenderer). Additionally, the mitk::BaseData or mitk::DataNode corresponding to the picked object in the (3D) scene can be retrieved.

Examples:: mitkMoveSurfaceInteractor.cpp.
