Hi all , 

I'm a young french student , who is begining to program with GTK , but 
i have a problem with an entry , i explain :

I want to display an entry , and take the "char" which is put in this entry and 
passed it as an argument for an other function .

I hope that someone will help me :)

Thanks .


Note: i don't have find some information about using entry in GTK+

This is my source :

entry_4 ()
  static GtkWidget *window = NULL;
  GtkWidget *box1;
  GtkWidget *box2;
  GtkWidget *entry;
  GtkWidget *button;
  GtkWidget *separator;
  gchar *host;
  if (!window) 
        window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
        gtk_signal_connect (GTK_OBJECT (window), "destroy",
                           (GtkSignalFunc) destroy_window,
        gtk_window_set_title (GTK_WINDOW (window), "Scan");
        gtk_container_border_width (GTK_CONTAINER (window), 0);
        box1 = gtk_vbox_new (FALSE ,0);
        gtk_container_add (GTK_CONTAINER (window),box1);
        gtk_widget_show (box1);
        box2 = gtk_vbox_new (FALSE ,10);
        gtk_container_border_width (GTK_CONTAINER (box2), 10);
        gtk_box_pack_start (GTK_BOX (box1), box2, TRUE, TRUE, 0);
        gtk_widget_show (box2); 

/* This is my entry */        
        entry = gtk_entry_new ();
        host = gtk_entry_get_text (GTK_ENTRY (entry));
/* I want to put localhost as default argument */
        gtk_entry_set_text (GTK_ENTRY (entry), "localhost");
        gtk_box_pack_start (GTK_BOX (box2), entry, TRUE, TRUE, 0);
        gtk_widget_show (entry);
        separator = gtk_hseparator_new ();
        gtk_box_pack_start (GTK_BOX (box1), separator, TRUE, TRUE, 0);
        gtk_widget_show (separator);
        box2 = gtk_hbox_new (FALSE ,10);
        gtk_container_border_width (GTK_CONTAINER (box2), 5);
        gtk_box_pack_start (GTK_BOX (box1), box2, TRUE, TRUE, 0);
        gtk_widget_show (box2);
        button = gtk_button_new_with_label ("Ok");
/* scan_host is the function where i want to put the char which is enter in the 
entry */
        gtk_signal_connect (GTK_OBJECT (button), "clicked",
                           (GtkSignalFunc) scan_host, 
        gtk_box_pack_start (GTK_BOX (box2), button, TRUE, TRUE, 0);
        gtk_widget_grab_default (button);
        gtk_widget_show (button);

        button = gtk_button_new_with_label ("Cancel");
        gtk_signal_connect_object (GTK_OBJECT (button), "clicked",
                                  (GtkSignalFunc) gtk_widget_destroy,
                                   GTK_OBJECT (window));
        gtk_box_pack_start (GTK_BOX (box2), button, TRUE, TRUE, 0);
        gtk_widget_show (button); 

  if (!GTK_WIDGET_VISIBLE (window))
    gtk_widget_show (window);
