+// AutoLayout Declaration
+/// @brief An auto layout feature for the CRowColumnView
+///
+/// The AutoLayout flexibly layouts the children of a CRowColumnView. The children are grouped and
+/// aligned among themselves depending on whether the style is a row (left to right) or a
+/// column (top to bottom). The group is moved inside the parent to either of the nine
+/// positions (top-left, top-center, top-right, middle-left, middle-center, middle-right,
+/// bottom-left, bottom-center or bottom-right). If the size of the parent is changed, the layout
+/// and alignment of the group is always retained.
