+    \class Q3Grid
+    \brief The Q3Grid widget provides simple geometry management of its children.
+
+    \compat
+
+    The grid places its widgets either in columns or in rows depending
+    on its orientation.
+
+    The number of rows \e or columns is defined in the constructor.
+    All the grid's children will be placed and sized in accordance
+    with their sizeHint() and sizePolicy().
+
+    Use setMargin() to add space around the grid itself, and
+    setSpacing() to add space between the widgets.
