     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.
