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