|
// Class Description:
|
|
//
|
|
// G4CallbackModel calls a user-defined function containing, for
|
|
// example, calls to the Draw methods of G4VVisManager. 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 user instantiates a function object containing, for example,
|
|
// calls to the Draw methods of G4VVisManager. 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.
