   1 \section{\class{wxNotebook}}\label{wxnotebook}
   2
   3 This class represents a notebook control, which manages multiple windows with associated tabs.
   4
   5 To use the class, create a wxNotebook object and call \helpref{AddPage}{wxnotebookaddpage} or \helpref{InsertPage}{wxnotebookinsertpage},
   6 passing a window to be used as the page. Do not explicitly delete the window for a page that is currently
   7 managed by wxNotebook.
   8
   9 {\bf wxNotebookPage} is a typedef for wxWindow.

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

  44 \wxheading{Page backgrounds}
  45
  46 On Windows XP, the default theme paints a gradient on the notebook's pages.
  47 If you wish to suppress this theme, for aesthetic or performance reasons,
  48 there are three ways of doing it. You can use wxNB\_NOPAGETHEME to disable
  49 themed drawing for a particular notebook, you can call {\tt wxSystemOptions::SetOption}
  50 to disable it for the whole application, or you can disable it for individual
  51 pages by using {\tt SetBackgroundColour}.
  52
  53 To disable themed pages globally:
  54
  55 \begin{verbatim}
  56     wxSystemOptions::SetOption(wxT("msw.notebook.themed-background"), 0);
  57 \end{verbatim}
  58
  59 Set the value to 1 to enable it again.
  60
  61 To give a single page a solid background that more or less fits in with the
  62 overall theme, use:
  63
  64 \begin{verbatim}
  65     wxColour col = notebook->GetThemeBackgroundColour();
  66     if (col.Ok())
  67     {
  68         page->SetBackgroundColour(col);
  69     }
  70 \end{verbatim}
  71
  72 On platforms other than Windows, or if the application is not using Windows
  73 themes, {\tt GetThemeBackgroundColour} will return an uninitialised colour object,
  74 and the above code will therefore work on all platforms.
