-    The anchor layout is a layout where one can specify how widgets should be placed relative to
-    each other. The specification is called an anchor, and it is set up by calling anchor().
+    The anchor layout allows developers to specify how widgets should be placed relative to
+    each other, and to the layout itself. The specification is made by adding anchors to the
+    layout by calling addAnchor(), addAnchors() or addCornerAnchors().
+
+    Existing anchors in the layout can be accessed with the anchor() function.
+    Items that are anchored are automatically added to the layout, and if items
+    are removed, all their anchors will be automatically removed.
+
+    \beginfloatleft
+    \inlineimage simpleanchorlayout-example.png Using an anchor layout to align simple colored widgets.
+    \endfloat
+
     Anchors are always set up between edges of an item, where the "center" is also considered to
-    be an edge. Considering this example:
-    \code
-        QGraphicsAnchorLayout *l = new QGraphicsAnchorLayout;
-        QGraphicsWidget *a = new QGraphicsWidget;
-        QGraphicsWidget *b = new QGraphicsWidget;
-        l->anchor(a, Qt::AnchorRight, b, Qt::AnchorLeft);
-    \endcode
-
-    Here is the right edge of item A anchored to the left edge of item B, with the result that
-    item B will be placed to the right of item A, with a spacing between A and B. If the
-    spacing is negative, the items will overlap to some extent. Items that are anchored are
-    automatically added to the layout, and if items are removed, all their anchors will be
-    automatically removed
-
-    \section1 Size Hints and Size Policies in QGraphicsAnchorLayout
-
-    QGraphicsAnchorLayout respects each item's size hints and size policies. However it does
-    not respect stretch factors currently. This might change in the future, so please refrain
-    from using stretch factors in anchor layout to avoid any future regressions.
-
-    \section1 Spacing within QGraphicsAnchorLayout
-
-    Between the items, the layout can distribute some space. If the spacing has not been
-    explicitly specified, the actual amount of space will usually be 0, but if the first edge
-    is the "opposite" of the second edge (i.e. Right is anchored to Left or vice-versa), the
-    size of the anchor will be queried from the style through the pixelMetric
-    PM_LayoutHorizontalSpacing (or PM_LayoutVerticalSpacing for vertical anchors).
+    be an edge. Consider the following example:
+
+    \snippet examples/graphicsview/simpleanchorlayout/main.cpp adding anchors
+
+    Here, the right edge of item \c a is anchored to the left edge of item \c b and the bottom
+    edge of item \c a is anchored to the top edge of item \c b, with the result that
+    item \c b will be placed diagonally to the right and below item \c b.
+
+    The addCornerAnchors() function provides a simpler way of anchoring the corners
+    of two widgets than the two individual calls to addAnchor() shown in the code
+    above. Here, we see how a widget can be anchored to the top-left corner of the enclosing
+    layout:
+
+    \snippet examples/graphicsview/simpleanchorlayout/main.cpp adding a corner anchor
+
+    In cases where anchors are used to match the widths or heights of widgets, it is
+    convenient to use the addAnchors() function. As with the other functions for specifying
+    anchors, it can also be used to anchor a widget to a layout.
+
+    \clearfloat
+    \section1 Size Hints and Size Policies in an Anchor Layout
+
+    QGraphicsAnchorLayout respects each item's size hints and size policies.
+    Note that there are some properties of QSizePolicy that are \l{Known issues}{not respected}.
+
+    \section1 Spacing within an Anchor Layout
+
+    The layout may distribute some space between the items. If the spacing has not been
+    explicitly specified, the actual amount of space will usually be 0.
+
+    However, if the first edge is the \e opposite of the second edge (e.g., the right edge
+    of the first widget is anchored to the left edge of the second widget), the size of the
+    anchor will be queried from the style through a pixel metric:
+    \l{QStyle::}{PM_LayoutHorizontalSpacing} for horizontal anchors and
+    \l{QStyle::}{PM_LayoutVerticalSpacing} for vertical anchors.
+
+    If the spacing is negative, the items will overlap to some extent.
+
+
+    \section1 Known issues
+    There are some features that QGraphicsAnchorLayout currently does not support.
+    This might change in the future, so avoid using these features if you want to
+    avoid any future regressions in behaviour:
+    \list
+
+    \o Stretch factors are not respected.
+
+    \o QSizePolicy::ExpandFlag is not respected.
+
+    \o Height for width is not respected.

-    Calculate the "expanding" keyframe
-
-    This new keyframe sits between the already existing sizeAtPreferred and
-    sizeAtMaximum keyframes. Its goal is to modify the interpolation between
-    the latter as to respect the "expanding" size policy of some anchors.
-
-    Previously all items would be subject to a linear interpolation between
-    sizeAtPreferred and sizeAtMaximum values. This will change now, the
-    expanding anchors will change their size before the others. To calculate
-    this keyframe we use the following logic:
-
-    1) Ask each anchor for their desired expanding size (ad->expSize), this
-    value depends on the anchor expanding property in the following way:
-
-    - Expanding normal anchors want to grow towards their maximum size
-    - Non-expanding normal anchors want to remain at their preferred size.
-    - Sequential anchors wants to grow towards a size that is calculated by:
-        summarizing it's child anchors, where it will use preferred size for non-expanding anchors
-        and maximum size for expanding anchors.
-    - Parallel anchors want to grow towards the smallest maximum size of all the expanding anchors.
-
-    2) Clamp their desired values to the value they assume in the neighbour
-    keyframes (sizeAtPreferred and sizeAtExpanding)
-
-    3) Run simplex with a setup that ensures the following:
-
-      a. Anchors will change their value from their sizeAtPreferred towards
-         their sizeAtMaximum as much as required to ensure that ALL anchors
-         reach their respective "desired" expanding sizes.
-
-      b. No anchors will change their value beyond what is NEEDED to satisfy
-         the requirement above.
-
-    The final result is that, at the "expanding" keyframe expanding anchors
-    will grow and take with them all anchors that are parallel to them.
-    However, non-expanding anchors will remain at their preferred size unless
-    they are forced to grow by a parallel expanding anchor.
-
-    Note: For anchors where the sizeAtPreferred is bigger than sizeAtMaximum,
-          the visual effect when the layout grows from its preferred size is
-          the following: Expanding anchors will keep their size while non
-          expanding ones will shrink. Only after non-expanding anchors have
-          shrinked all the way, the expanding anchors will start to shrink too.

     The function pos() gives the current cursor position, while oldPos() gives

+    There are a few similarities between the events QEvent::HoverEnter
+    and QEvent::HoverLeave, and the events QEvent::Enter and QEvent::Leave.
+    However, they are slightly different because we do an update() in the event
+    handler of HoverEnter and HoverLeave.
+
+    QEvent::HoverMove is also slightly different from QEvent::MouseMove. Let us
+    consider a top-level window A containing a child B which in turn contains a
+    child C (all with mouse tracking enabled):
+
+    \image hoverEvents.png
+
+    Now, if you move the cursor from the top to the bottom in the middle of A,

+        \o B::MouseMove

+
+    A QGesture instance is implicitly created when needed and is owned by Qt.

+
+    The gesture object may be delivered to the target object in a QGestureEvent if
+    the corresponding gesture is active or has just been canceled. Each event that
+    is delivered contains a list of gesture objects, since support for more than
