Its main purpose is to coordinate * distributed requests which cannot be aware of each other - lacking the * knowledge of whether they are really necessary or not. For example, two * objects might determine that a specific RenderWindow needs to be updated. * This would result in one unnecessary update, if both executed the update * on their own. * * The RenderingManager addresses this by letting each such object * request an update, and waiting for other objects to possibly * issue the same request. The actual update will then only be executed at a * well-defined point in the main event loop (this may be each time after * event processing is done). * * Convinience methods for updating all RenderWindows which have been * registered with the RenderingManager exist. If theses methods are not * used, it is not required to register (add) RenderWindows prior to using * the RenderingManager. * * The methods #ForceImmediateUpdate() and #ForceImmediateUpdateAll() can * be used to force the RenderWindow update execution without any delay, * bypassing the request functionality. * * The interface of RenderingManager is platform independent. Platform * specific subclasses have to be implemented, though, to supply an * appropriate event issueing for controlling the update execution process. * See method documentation for a description of how this can be done. * * \sa TestingRenderingManager An "empty" RenderingManager implementation which * can be used in tests etc. * */ class MITK_CORE_EXPORT RenderingManager : public itk::Object { public: mitkClassMacro(RenderingManager,itk::Object); typedef std::vector< vtkRenderWindow* > RenderWindowVector; typedef std::vector< float > FloatVector; typedef std::vector< bool > BoolVector; typedef itk::SmartPointer< DataStorage > DataStoragePointer; typedef itk::SmartPointer< GlobalInteraction > GlobalInteractionPointer; enum RequestType { REQUEST_UPDATE_ALL = 0, REQUEST_UPDATE_2DWINDOWS, REQUEST_UPDATE_3DWINDOWS }; static Pointer New(); /** Set the object factory which produces the desired platform specific * RenderingManager singleton instance. */ static void SetFactory( RenderingManagerFactory *factory ); /** Get the object factory which produces the platform specific * RenderingManager instances. */ static const RenderingManagerFactory *GetFactory(); /** Returns true if a factory has already been set. */ static bool HasFactory(); /** Get the RenderingManager singleton instance. */ static RenderingManager *GetInstance(); /** Returns true if the singleton instance does already exist. */ static bool IsInstantiated(); /** Adds a RenderWindow.
