+    \section1 Size Hints and Size Policies in QGraphicsGridLayout
+
+    QGraphicsGridLayout respects each item's size hints and size policies,
+    and when a cell in the grid has more space than the items can fill, each item
+    is arranged according to the layout's alignment for that item. You can set
+    an alignment for each item by calling setAlignment(), and check the
+    alignment for any item by calling alignment(). You can also set the alignment
+    for an entire row or column by calling setRowAlignment() and setColumnAlignment()
+    respectively.  By default, items are aligned to the top left.
