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. |
