| 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.
