Hello world not show

[Zhengrong Zang <zhengrong zang gmail com>]

I compiled code as below and without any problems, but nothing shown when run it, what should I do next?

/* example-start base base.c */ 

#include <gtk/gtk.h> 

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

     GtkWidget *window; 

     gtk_init (&argc, &argv); 

     window = gtk_window_new (GTK_WINDOW_TOPLEVEL);      

     gtk_widget_show  (window); 

     gtk_main (); 

     return(0);
} 

/* example-end */
