+ * @Short_description: Base class for widgets with alignments and padding
+ * @Title: GtkMisc
+ *
+ * The #GtkMisc widget is an abstract widget which is not useful itself, but
+ * is used to derive subclasses which have alignment and padding attributes.
+ *
+ * The horizontal and vertical padding attributes allows extra space to be
+ * added around the widget.
+ *
+ * The horizontal and vertical alignment attributes enable the widget to be
+ * positioned within its allocated area. Note that if the widget is added to
+ * a container in such a way that it expands automatically to fill its
+ * allocated area, the alignment settings will not alter the widgets position.
+ *
+ * <note>
+ * Note that the desired effect can in most cases be achieved by using the
+ * #GtkWidget:halign, #GtkWidget:valign and #GtkWidget:margin properties
+ * on the child widget, so GtkMisc should not be used in new code.
+ * </note>
