+
+    By setting the size policy on an anchor you can configure how the item can resize itself
+    from its preferred spacing. For instance, if the anchor has the size policy
+    QSizePolicy::Minimum, the spacing is the minimum size of the anchor. However, its size
+    can grow up to the anchors maximum size. If the default size policy is QSizePolicy::Fixed,
+    the anchor can neither grow or shrink, which means that the only size the anchor can have
+    is the spacing. QSizePolicy::Fixed is the default size policy.
+    QGraphicsAnchor always has a minimum spacing of 0 and a very large maximum spacing.
