Re: Closing an application

[Alejandro García Rodríguez <agarcia die upm es>]

	Hi, Shiraz!

	The way i have learnt to exit an application is the following. I
will show you in another little code application. For further information
i would read the gtk+2.0 tutorial because you have a lot of posibilities
for doing this according to your requirements.

#include <gtk/gtk.h>
int main( int argc,
          char* argv[] )
{
  GtkWidget *window;
  GtkWidget *button;

  gtk_init( &argc, &argv );

  window = gtk_window_new( GTK_WINDOW_TOPLEVEL );
  g_signal_connect( G_OBJECT (window), "delete_event",
                    G_CALLBACK (gtk_main_quit), NULL );
  g_signal_connect_swapped( G_OBJECT (window), "destroy",
                            G_CALLBACK (gtk_main_quit), NULL );
  gtk_widget_set_size_request (GTK_WIDGET (window), 200, 100);

  button = gtk_button_new_with_label( "quit" );
  g_signal_connect( G_OBJECT (button), "clicked",
                    G_CALLBACK (gtk_main_quit), NULL );
  gtk_container_add (GTK_CONTAINER(window), button);
  gtk_widget_show( button );

  gtk_widget_show( window );

  gtk_main( ) ;
  return 0;
}
