Functions
int	main (int argc, char *argv[])
	Entry point for the gboard example application.

Detailed Description

This example demonstrates two modes:

• GUI mode (enabled with --gui): creates a QApplication, shows a QMainWindow containing GBoard, and installs a GUI_Session so Geant4 output is forwarded to the board.
• CLI mode (default): runs without creating Qt objects and simply exits after setup messages.

The example also supports a timeout (scalar option tt) that automatically quits the Qt event loop after the specified duration.

Key behaviors illustrated:

• Creating module options via gboard::defineOptions().
• Constructing a GBoard owned by the Qt parent (the main window).
• Creating a GUI_Session that forwards Geant4 output to the board (session does not own the board).
• Running and terminating a Qt event loop using QTimer.

Function Documentation

main()

int main	(	int	argc,
		char *	argv[] )

Responsibilities:

• Initializes options and logging.
• Optionally initializes Qt GUI objects and shows a window that embeds GBoard.
• Initializes a Geant4 visualization manager to ensure Geant4 subsystems are active for the demo.
• In GUI mode, installs GUI_Session to route Geant4 UI output to the board.
• Exits either after the Qt event loop ends (GUI) or immediately (CLI).

Parameters

argc	Standard C/C++ argument count.
argv	Standard C/C++ argument vector.

Returns

EXIT_SUCCESS on normal completion, otherwise a non-zero status.
