-/**
- * gtk_widget_destroy:
- * @widget: a #GtkWidget
- *
- * Destroys a widget.
- *
- * When a widget is destroyed all references it holds on other objects
- * will be released:
- *
- *  - if the widget is inside a container, it will be removed from its
- *  parent
- *  - if the widget is a container, all its children will be destroyed,
- *  recursively
- *  - if the widget is a top level, it will be removed from the list
- *  of top level widgets that GTK+ maintains internally
- *
- * It's expected that all references held on the widget will also
- * be released; you should connect to the #GtkWidget::destroy signal
- * if you hold a reference to @widget and you wish to remove it when
- * this function is called. It is not necessary to do so if you are
- * implementing a #GtkContainer, as you'll be able to use the
- * #GtkContainerClass.remove() virtual function for that.
- *
- * It's important to notice that gtk_widget_destroy() will only cause
- * the @widget to be finalized if no additional references, acquired
- * using g_object_ref(), are held on it. In case additional references
- * are in place, the @widget will be in an "inert" state after calling
- * this function; @widget will still point to valid memory, allowing you
- * to release the references you hold, but you may not query the widget's
- * own state.
- *
- * You should typically call this function on top level widgets, and
- * rarely on child widgets.
- *
- * See also: gtk_container_remove()
