+    \ingroup graphicsview-api
+
+    The graphics anchor provides an API that enables you to query and manipulate the
+    properties an anchor has. When an anchor is added to the layout with
+    QGraphicsAnchorLayout::addAnchor(), a QGraphicsAnchor instance is returned where the properties
+    are initialized to their default values. The properties can then be further changed, and they
+    will be picked up the next time the layout is activated.

     high z-values. Stacking order applies to sibling items; parents are always
     drawn before their children.
 
+    \section1 Sorting
+
+    All items are drawn in a defined, stable order, and this same order decides
+    which items will receive mouse input first when you click on the scene.
+    Normally you don't have to worry about sorting, as the items follow a
+    "natural order", following the logical structure of the scene.
+
+    An item's children are stacked on top of the parent, and sibling items are
+    stacked by insertion order (i.e., in the same order that they were either
+    added to the scene, or added to the same parent). If you add item A, and
+    then B, then B will be on top of A. If you then add C, the items' stacking
+    order will be A, then B, then C.
+
+    \image graphicsview-zorder.png
+
+    This example shows the stacking order of all limbs of the robot from the
+    \l{graphicsview/dragdroprobot}{Drag and Drop Robot} example. The torso is
+    the root item (all other items are children or descendants of the torso),
+    so it is drawn first. Next, the head is drawn, as it is the first item in
+    the torso's list of children. Then the upper left arm is drawn. As the
+    lower arm is a child of the upper arm, the lower arm is then drawn,
+    followed by the upper arm's next sibling, which is the upper right arm, and
+    so on.
+
+    For advanced users, there are ways to alter how your items are sorted:
+
+    \list
+    \o You can call setZValue() on an item to explicitly stack it on top of, or
+    under, other sibling items. The default Z value for an item is 0. Items
+    with the same Z value are stacked by insertion order.
+
+    \o You can call stackBefore() to reorder the list of children. This will
+    directly modify the insertion order.
+
+    \o You can set the ItemStacksBehindParent flag to stack a child item behind
+    its parent.
+    \endlist
+
+    The stacking order of two sibling items also counts for each item's
+    children and descendant items. So if one item is on top of another, then
+    all its children will also be on top of all the other item's children as
+    well.

-    \preliminary
 
-    Softkeys API is a platform independent way of mapping actions to (hardware)keys
-    and toolbars provided by the underlying platform.
+    Softkeys are usually physical keys on a device that have a corresponding label or
+    other visual representation on the screen that is generally located next to its
+    physical counterpart. They are most often found on mobile phone platforms. In
+    modern touch based user interfaces it is also possible to have softkeys that do
+    not correspond to any physical keys. Softkeys differ from other onscreen labels
+    in that they are contextual.
 
-    There are three major use cases supported. First one is a mobile device
-    with keypad navigation and no touch ui. Second use case is a mobile
-    device with touch ui. Third use case is desktop. For now the softkey API is
-    only implemented for Series60.
+    In Qt, contextual softkeys are added to a widget by calling addAction() and
+    passing a \c QAction with a softkey role set on it. When the widget
+    containing the softkey actions has focus, its softkeys should appear in
+    the user interface. Softkeys are discovered by traversing the widget
+    heirarchy so it is possible to define a single set of softkeys that are
+    present at all times by calling addAction() for a given top level widget.
 
-    QActions are set to widget(s) via softkey API. Actions in focused widget are
-    mapped to native toolbar or hardware keys. Even though the API allows to set
-    any amount of widgets there might be physical restrictions to amount of
-    softkeys that can be used by the device.
+    On some platforms, this concept overlaps with \c QMenuBar such that if no
+    other softkeys are found and the top level widget is a QMainWindow containing
+    a QMenuBar, the menubar actions may appear on one of the softkeys.
 
-    \e Series60: For series60 menu button is automatically mapped to left
-    soft key if there is QMainWindow with QMenuBar in widgets parent hierarchy.
+    Note: Currently softkeys are only supported on the Symbian Platform.
