Built-in Commands
Geant4 has various built-in user interface commands, each of which
corresponds roughly to a Geant4 category. These commands can be
used
interactively via a (Graphical) User Interface - (G)UI,
in a macro file via /control/execute <command>,
within C++ code with the ApplyCommand method of G4UImanager.
Note
The availability of individual commands, the ranges of parameters,
the available candidates on individual command parameters
vary according to the implementation of
your application and may even vary
dynamically during the execution of your job.
