{

   g_signal_connect(G_OBJECT(skipstone->embed), "script-alert", G_CALLBACK(handle_script_alert), skipstone);
   g_signal_connect(G_OBJECT(skipstone->embed), "script-confirm", G_CALLBACK(handle_script_confirm), skipstone);
   g_signal_connect(G_OBJECT(skipstone->embed), "script-prompt", G_CALLBACK(handle_script_prompt), skipstone);


  GtkWidget *dialog;
  D_ENTER;
  dialog = gtk_message_dialog_new(GTK_WINDOW(skipstone->window),
            GTK_DIALOG_DESTROY_WITH_PARENT,
            GTK_MESSAGE_INFO,
            GTK_BUTTONS_OK,
            message);
  gtk_window_set_title(GTK_WINDOW(dialog), KTITLE);
  gtk_window_set_position(GTK_WINDOW(dialog), GTK_WIN_POS_CENTER);
  gtk_dialog_run(GTK_DIALOG(dialog));
  gtk_widget_destroy(dialog);
  D_RETURN_(TRUE);
}

+gboolean handle_script_confirm(WebKitWebView *web_view, WebKitWebFrame *frame, gchar *message, gboolean **confirmed, SkipStone *skipstone)
{
  GtkWidget *dialog;
  D_ENTER;
  *confirmed = FALSE;
  dialog = gtk_message_dialog_new(GTK_WINDOW(skipstone->window),
            GTK_DIALOG_DESTROY_WITH_PARENT,
            GTK_MESSAGE_QUESTION,
            GTK_BUTTONS_OK_CANCEL,
            message);
  gtk_window_set_title(GTK_WINDOW(dialog), KTITLE);
  gtk_window_set_position(GTK_WINDOW(dialog), GTK_WIN_POS_CENTER);
  gint result = gtk_dialog_run(GTK_DIALOG(dialog));
  if(result == GTK_RESPONSE_OK)
    *confirmed = TRUE;
  gtk_widget_destroy(dialog);
  D_RETURN_(TRUE);
}

gboolean handle_script_prompt(WebKitWebView *web_view, WebKitWebFrame *frame, gchar *message, gchar *default_text, gchar **text, SkipStone *skipstone)
{
  GtkWidget *dialog;
  GtkWidget *entry, *message_area;
  D_ENTER;
  dialog = gtk_message_dialog_new(GTK_WINDOW(skipstone->window),
            GTK_DIALOG_DESTROY_WITH_PARENT,
            GTK_MESSAGE_QUESTION,
            GTK_BUTTONS_OK,
            message);
  gtk_window_set_title(GTK_WINDOW(dialog), KTITLE);
  gtk_window_set_position(GTK_WINDOW(dialog), GTK_WIN_POS_CENTER);
  message_area = gtk_dialog_get_content_area(GTK_DIALOG(dialog));
  entry = gtk_entry_new();
  gtk_entry_set_text(GTK_ENTRY(entry), default_text);
  gtk_widget_show(entry);
  gtk_container_add (GTK_CONTAINER (message_area), entry);
  gtk_dialog_run(GTK_DIALOG(dialog));
  *text = g_strdup(gtk_entry_get_text(GTK_ENTRY(entry)));
  gtk_widget_destroy(dialog);
  D_RETURN_(TRUE);
}

brilliant.
