\section{\class{wxRegion}}\label{wxregion}
-A wxRegion represents a simple or complex region on a device context or window. It uses
-reference counting, so copying and assignment operations are fast.
+A wxRegion represents a simple or complex region on a device context or window.
+
+This class uses \helpref{reference counting and copy-on-write}{trefcount}
+internally so that assignments between two instances of this class are very
+cheap. You can therefore use actual objects instead of pointers without
+efficiency problems. If an instance of this class is changed it will create
+its own data internally so that other instances, which previously shared the
+data using the reference counting, are not affected.
\wxheading{Derived from}
\func{}{wxRegion}{\param{const wxRegion\&}{ region}}
-Constructs a region by copying another region.
+Copy constructor, uses \helpref{reference counting}{trefcount}.
\func{}{wxRegion}{\param{size\_t}{ n}, \param{const wxPoint }{*points}, \param{int }{fillStyle = wxWINDING\_RULE}}
provided array. {\it fillStyle} parameter may have values
{\tt wxWINDING\_RULE} or {\tt wxODDEVEN\_RULE}.
-{\bf NB:} This constructor is only implemented for Win32 and GTK+ wxWidgets ports.
