+/**
+   This class defines methods for streaming widget data.
+
+   For each widget type rules are defined telling which attributes should be
+   streamed. If you need to stream other attributes or to avoid streaming
+   certain attributes, then this may be obtained by editing the property
+   map, which is obtained by calling @ref propertyMap. For further control
+   inherit from this class and override @ref toStream and @ref fromStream.
+
+   The following example shows how you can avoid streaming
+   <tt>numDigits</tt> for a QLCDNumber. The same approach applies if you
+   want to add extra properties to be streamed.
+   <pre>
+   KWidgetStreamer streamer;
+   KWidgetStreamer::PropertyMap& map = streamer.propertyMap();
+   KWidgetStreamer::PropertyList& list = *map.find("QLCDNumber");
+   list.remove("numDigits");
+   </pre>
