| 33 | // Class Description: |
---|
| 34 | // |
---|
| 35 | // G4CallbackModel calls a user-defined function containing, for |
---|
| 36 | // example, calls to the Draw methods of G4VVisManager or the |
---|
| 37 | // *Primitive* methods of G4VGraphicsScene. This allows the user to |
---|
| 38 | // add his own graphical objects to a scene. The idea is that the |
---|
| 39 | // callback function is invoked by the vis system to refresh the |
---|
| 40 | // screen or remake a graphical database whenever required. The |
---|
| 41 | // function class must contain: |
---|
| 42 | // |
---|
| 43 | // void operator()(G4VGraphicsScene&, const G4Transform3D&) |
---|
| 44 | // |
---|
| 45 | // A base class G4VUserVisAction is provided in the visualisation |
---|
| 46 | // category. A G4CallbackModel is made by instantiating this template |
---|
| 47 | // with a pointer to the function object. The G4VisManager does this |
---|
| 48 | // for the user if he/she registers it (SetUserAction) and issues the |
---|
| 49 | // command /vis/scene/add/userAction. See the User Guide for |
---|
| 50 | // Application Developers, Section 8.8.7 and 8.8.8. |
