\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
from the backing store into the window surface if the top-level widget
has the Qt::WA_TranslucentBackground attribute. If this mode is set,
alpha values are copied regardless of the value of that attribute.
\value NativePaintModeDisable Do not paint anything into the native window
surface.
