\section{\class{wxNotebook}}\label{wxnotebook}

This class represents a notebook control, which manages multiple windows with associated tabs.

To use the class, create a wxNotebook object and call \helpref{AddPage}{wxnotebookaddpage} or \helpref{InsertPage}{wxnotebookinsertpage},
passing a window to be used as the page. Do not explicitly delete the window for a page that is currently
managed by wxNotebook.

{\bf wxNotebookPage} is a typedef for wxWindow.

\twocolitem{\windowstyle{wxNB\_BOTTOM}}{Place tabs under instead of above the notebook pages.}
\twocolitem{\windowstyle{wxNB\_FIXEDWIDTH}}{(Windows only) All tabs will have same width.}
\twocolitem{\windowstyle{wxNB\_MULTILINE}}{(Windows only) There can be several rows of tabs.}
\twocolitem{\windowstyle{wxNB\_NOPAGETHEME}}{(Windows only) Display a solid colour on notebook pages, and not a gradient, which can reduce performance.}
\twocolitem{\windowstyle{wxNB\_FLAT}}{(Windows CE only) Show tabs in a flat style.}

\end{twocollist}

The styles \texttt{wxNB\_LEFT}, \texttt{RIGHT} and \texttt{BOTTOM} are not
supported under Microsoft Windows XP when using visual themes.

\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.
