\wxheading{Page backgrounds}
On Windows XP, the default theme paints a gradient on the notebook's pages.
If you wish to suppress this theme, for aesthetic or performance reasons,
there are three ways of doing it. You can use wxNB\_NOPAGETHEME to disable
themed drawing for a particular notebook, you can call {\tt wxSystemOptions::SetOption}
to disable it for the whole application, or you can disable it for individual
pages by using {\tt SetBackgroundColour}.
To disable themed pages globally:
\begin{verbatim}
wxSystemOptions::SetOption(wxT("msw.notebook.themed-background"), 0);
\end{verbatim}
Set the value to 1 to enable it again.
To give a single page a solid background that more or less fits in with the
overall theme, use:
\begin{verbatim}
wxColour col = notebook->GetThemeBackgroundColour();
if (col.Ok())
{
page->SetBackgroundColour(col);
}
\end{verbatim}
On platforms other than Windows, or if the application is not using Windows
themes, {\tt GetThemeBackgroundColour} will return an uninitialised colour object,
and the above code will therefore work on all platforms.

If running under Windows and themes are enabled for the application, this function
returns a suitable colour for painting the background of a notebook page, and can be passed
to {\tt SetBackgroundColour}. Otherwise, an uninitialised colour will be returned.
