Function Documentation

• Creates a GOptions instance to parse command-line arguments.
• Reads:
  • gui : whether to run with a Qt GUI.
  • tt : timeout (milliseconds) after which the GUI exits automatically.
• If gui is true:
  • Creates QApplication
  • Instantiates GQTButtonsWidget with two icon base names
  • Shows the widget
  • Uses QTimer::singleShot() to quit after tt milliseconds
• If gui is false:
  • Runs in CLI mode (no GUI loop)

Parameters
