[Glade-users] [Glade-users][Re] ? on lookup widget(...)

[liberta kldp org (J. Seo)]

No, the first parameter doesn't mean the pointer to the parent widget.
It could be any widget which is in the same hierarchy, of course, with the
second parameter.

Refer to the definition for lookup_widget ();  (comment lines included)

/* In "support.c" generated by Glade */
GtkWidget*
lookup_widget                          (GtkWidget       *widget,
                                        const gchar     *widget_name)
{
  GtkWidget *parent, *found_widget;

  for (;;)     // finding "Root (Parent)" by the first param.
    {
      if (GTK_IS_MENU (widget))
        parent = gtk_menu_get_attach_widget (GTK_MENU (widget));
      else
        parent = widget->parent;
      if (parent == NULL)
        break;
      widget = parent;
    }

  found_widget = (GtkWidget*) gtk_object_get_data (GTK_OBJECT (widget),
                                                   widget_name);  // 
finding the requested widget
                                                                        
       // with its name.
  if (!found_widget)
    g_warning ("Widget not found: %s", widget_name);
  return found_widget;
}
