+    \enum QSymbianGraphicsSystemHelper::NativePaintMode
+
+    This enum controls the way in which QWidget paints content from the Qt
+    backing store into the corresponding native window surface.
+
+    \value NativePaintModeDefault Default painting behaviour.
+    \value NativePaintModeZeroFill Ignore contents of backing store, and
+        fill the window surface region with zeroes.
+    \value NativePaintModeWriteAlpha By default, alpha values are only copied

+        has the Qt::WA_TranslucentBackground attribute.  If this mode is set,
+        alpha values are copied regardless of the value of that attribute.
