thanks to all of them!
Geant4 User Interface (UI)
Geant4 UI
 Geant4 supports various built-in UI commands.
 UI command consists of
command directory, command, and parameter.
Ex) /run/beamOn 10
 Geant4 has a two types of UI processing (batch mode,
interactive mode)
 We can check the list of built-in commands in this web site.

Geant4 User Interface (UI)
‘Hard-coded’ batch mode
 Geant4 UI Command can be run in Geant4 source code.
(called ‘Hard-coded’ batch mode)
 Example:
int main(int argc, char** argv)
{…
G4UImanager* UImanager = G4UImanager::GetUIpointer();
UImanager->ApplyCommand("/run/verbose 1");
UImanager->ApplyCommand("/event/verbose 1");
UImanager->ApplyCommand("/tracking/verbose 1");
…
}

Geant4 User Interface (UI)
Batch mode with macro file
 Geant4 simulation will run in batch mode with macro file.
 Example:
int main(int argc, char** argv)
{…
G4UImanager* UImanager = G4UImanager::GetUIpointer();
if(argc==1) {
// Define UI session for interactive mode
} else {
// Define batch mode using UImanager class
G4String command = "/control/execute " + argv[1];
UImanager->ApplyCommand(command);
}
…
}

Geant4 User Interface (UI)
Batch mode with macro file
 The example will be executed with below command:
> example run.mac
 Example - run.mac file:
# Macro file: run.mac
# set verbose level for this run
/run/verbose 2
/event/verbose 0
/tracking/verbose 1
/gun/particle e/gun/energy 1 GeV
/run/beamOn 100
※ First ‘#’ is used for comment line in macro file.

Geant4 User Interface (UI)
Interactive mode - Character UI (CUI)
 Geant4 provide character user interface (CUI) by using
G4UIterminal class (or G4UIWin32 in windows OS) as
interactive mode.
 Example:
int main(int argc, char** argv)
{…
if(argc==1) {
// Define UI session for interactive mode
G4UIsession* session = new G4UIterminal(new G4UItcsh);
session->SessionStart();
delete session;
}
…
}

Geant4 User Interface (UI)
Interactive mode - Graphical UI (GUI)
 Geant4 supports various graphical user interface (GUI) by
using G4UIExecutive class.
 Example:
int main(int argc, char** argv)
{…
if(argc==1) {
// Define UI session for interactive mode
G4UIExecutive* ui = new G4UIExecutive(argc, argv, “XX”);
session->SessionStart();
delete session;
}
…
}

Geant4 User Interface (UI)
Interactive mode - Graphical UI (GUI)
 User can choose a specific interface initial parameter of
G4UIExecutive class.
ex) G4UIExecutive* ui = new G4UIExecutive(argc, argv, “xx”)
(where xx = qt, xm, win32, gag, tcsh, …)
Run with Xm GUI
9
Geant4 User Interface (UI)
Interactive mode - Qt UI
 The one of Geant4 GUI Application
 Qt (UI) with OpenGL (Graphic viewer)
 If GEANT4_USE_QT=1 when geant4 was installed, Qt is
default UI in Geant4.
 Homepage - http://qt.digia.com/


Enable/Disable specific geometry using “Scene tree”
Command (or Command parameter) check
Geometry viewer
Run specific macro, command alias, etc…
