+\section{\class{wxRegionIterator}}\label{wxregioniterator}
+
+This class is used to iterate through the rectangles in a region,
+typically when examining the damaged regions of a window within an OnPaint call.
+
+To use it, construct an iterator object on the stack and loop through the
+regions, testing the object and incrementing the iterator at the end of the loop.
+
+See \helpref{wxWindow::OnPaint}{wxwindowonpaint} for an example of use.
