{
change_passwd_window=create_window(change_passwd_window,frame1,"Change Password...",2);
.....
.....
old_passwd_text=gtk_entry_new();
...
...
gtk_widget_show_all(change_passwd_window);
}

GtkWidget* create_window(GtkWidget *AppWindow,GtkWidget *child,char *title,int screen)
{     
     char * list[1] ;
       int count = 1 ;
       XTextProperty text ;
     Window xwin = None ;

     list[0] = title ;
       AppWindow = gtk_window_new(GTK_WINDOW_TOPLEVEL);
       gtk_widget_set_usize(GTK_WIDGET(AppWindow) ,238,296);
       gtk_widget_set_uposition(GTK_WIDGET(AppWindow),0,0) ;
       gtk_window_set_policy(GTK_WINDOW(AppWindow), FALSE, FALSE, TRUE) ;
       gtk_widget_realize( GTK_WIDGET(AppWindow)) ;
       gtk_container_set_border_width (GTK_CONTAINER(AppWindow), 0);
     gtk_container_add(GTK_CONTAINER(AppWindow),child);
 
     if(XStringListToTextProperty(list,count,&text))
     {
          xwin = GDK_WINDOW_XWINDOW(GTK_WIDGET(AppWindow)->window) ;
          XSetWMName(GDK_DISPLAY(),xwin,&text) ;
     }
     if( screen == 1)
          ParentWindow = xwin ;
     if( screen == 2 )
          XReparentWindow( GDK_DISPLAY( ), xwin, ParentWindow,1,1); 
     return AppWindow ;
