Programming in GNOME with C++

Listing 1: Gtkmm source code

/*
 * Paulo Pinto ([email protected]) (c) 2001
 * A very simple hello world to
 * show basic Gtk-- usage. 
 */
#include <gtk--/main.h>
#include <gtk--/window.h>

// Please note that in ANSI C++ the
// return is optional
int main (int argc, char *argv [])
{
  // Initialize the framework
  Gtk::Main kit (argc, argv);
  Gtk::Window win;

  // Set the main window title
  win.set_title ("Hello World");

  // Connect the signal that is generated when the
  // user tries to close the window, to the
  // quit slot. This way the user will be able to
  // close the window by clicking on the 'X' mark.
  win.destroy.connect (Gtk::Main::quit.slot ());

  // Make the window appear
  win.show ();

  // Enter into the event loop
  kit.run ();
