This allows the user to 36 // add his own graphical objects to a scene. The idea is that the 37 // callback function is invoked by the vis system to refresh the 38 // screen or remake a graphical database whenever required. The 39 // function class must contain: 40 // 41 // void operator()(G4VGraphicsScene&,const G4ModelingParameters*) 42 // 43 // A base class G4VUserVisAction is provided in the visualisation 44 // category. A G4CallbackModel is made by instantiating this template 45 // with a pointer to the function object. The G4VisManager does this 46 // for the user if he/she registers it (Register*UserVisAction) and issues the 47 // command /vis/scene/add/userAction. See the User Guide for 48 // Application Developers. 49 50 #ifndef G4CALLBACKMODEL_HH 51 #define G4CALLBACKMODEL_HH 52 53 #include "G4VModel.hh" 54 55 template <class F> class G4CallbackModel: public G4VModel { 56 57 public: 58 G4CallbackModel(F* function): 59 fFunction(function) {} 60 ~G4CallbackModel() {} 61 void DescribeYourselfTo(G4VGraphicsScene& sceneHandler) { 62 (*fFunction)(sceneHandler, fpMP); 63 } 64 65 protected: 66 67 F* fFunction; 68 69 private: 70 71 // Private copy constructor and assigment operator - copying and 72 // assignment not allowed.
