+\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.
