     Begins a row move operation.
 
     When reimplementing a subclass, this method simplifies moving
     entities in your model. This method is responsible for moving
     persistent indexes in the model, which you would otherwise be
-    required to do yourself.

-    layoutAboutToBeChanged and layoutChanged directly along with
-    changePersistentIndexes.  layoutAboutToBeChanged is emitted by
-    this method for compatibility reasons.

     The \a sourceParent index corresponds to the parent from which the
-    rows are moved; \a sourceFirst and \a sourceLast are the row
-    numbers of the rows to be moved. The \a destinationParent index
-    corresponds to the parent into which the rows are moved. The \a
+    rows are moved; \a sourceFirst and \a sourceLast are the first and last
+    row numbers of the rows to be moved. The \a destinationParent index
+    corresponds to the parent into which those rows are moved. The \a
     destinationChild is the row to which the rows will be moved.  That
     is, the index at row \a sourceFirst in \a sourceParent will become
-    row \a destinationChild in \a destinationParent. Its siblings will
-    be moved correspondingly.
+    row \a destinationChild in \a destinationParent, followed by all other
+    rows up to \a sourceLast.
+
+    However, when moving rows down in the same parent (\a sourceParent
+    and \a destinationParent are equal), the rows will be placed before the
+    \a destinationChild index. That is, if you wish to move rows 0 and 1 so
+    they will become rows 1 and 2, \a destinationChild should be 3. In this
+    case, the new index for the source row \c i (which is between
+    \a sourceFirst and \a sourceLast) is equal to
+    \c {(destinationChild-sourceLast-1+i)}.
+
+    Note that if \a sourceParent and \a destinationParent are the same,
+    you must ensure that the \a destinationChild is not within the range
+    of \a sourceFirst and \a sourceLast + 1.  You must also ensure that you
+    do not attempt to move a row to one of its own children or ancestors.
+    This method returns false if either condition is true, in which case you
+    should abort your move operation.

+            For example, as shown in the diagram, we move three rows from
+            row 2 to 4 in the source, so \a sourceFirst is 2 and \a sourceLast is 4.

+            This moves the three rows rows 2, 3, and 4 in the source to become 2, 3 and 4 in
+            the destination. Other affected siblings are displaced accordingly.

+
+            For example, as shown in the diagram, we move three rows to a
+            collection of 6 existing rows (ending in row 5), so \a destinationStart is 6:
+
+            \snippet doc/src/snippets/code/src_corelib_kernel_qabstractitemmodel.cpp 7
+
+            This moves the target rows to the end of the target parent as 6, 7 and 8.

+            For example, as shown in the diagram, we move one item from row 2 to row 0,

+
+            \snippet doc/src/snippets/code/src_corelib_kernel_qabstractitemmodel.cpp 8
+
+            Note that other rows may be displaced accordingly. Note also that when moving
+            items within the same parent you should not attempt invalid or no-op moves. In
+            the above example, item 2 is at row 2 before the move, so it can not be moved
