  10     @class wxNotebook
  11
  12     This class represents a notebook control, which manages multiple windows with
  13     associated tabs.
  14
  15     To use the class, create a wxNotebook object and call wxNotebook::AddPage
  16     or wxNotebook::InsertPage, passing a window to be used as the page.
  17     Do not explicitly delete the window for a page that is currently managed by
  18     wxNotebook.
  19
  20     @b wxNotebookPage is a typedef for wxWindow.
  21
  22     @beginStyleTable
  23     @style{wxNB_TOP}
  24            Place tabs on the top side.
  25     @style{wxNB_LEFT}
  26            Place tabs on the left side.
  27     @style{wxNB_RIGHT}
  28            Place tabs on the right side.
  29     @style{wxNB_BOTTOM}
  30            Place tabs under instead of above the notebook pages.
  31     @style{wxNB_FIXEDWIDTH}
  32            (Windows only) All tabs will have same width.
  33     @style{wxNB_MULTILINE}
  34            (Windows only) There can be several rows of tabs.
  35     @style{wxNB_NOPAGETHEME}
  36            (Windows only) Display a solid colour on notebook pages, and not a
  37            gradient, which can reduce performance.
  38     @style{wxNB_FLAT}
  39            (Windows CE only) Show tabs in a flat style.
  40     @endStyleTable
  41
  42     The styles wxNB_LEFT, RIGHT and BOTTOM are not supported under
  43     Microsoft Windows XP when using visual themes.

  45     @beginEventEmissionTable{wxBookCtrlEvent}
  46     @event{EVT_NOTEBOOK_PAGE_CHANGED(id, func)}
  47         The page selection was changed.
  48         Processes a @c wxEVT_COMMAND_NOTEBOOK_PAGE_CHANGED event.
  49     @event{EVT_NOTEBOOK_PAGE_CHANGING(id, func)}
  50         The page selection is about to be changed.
  51         Processes a @c wxEVT_COMMAND_NOTEBOOK_PAGE_CHANGING event.
  52         This event can be vetoed.

  56     @section notebook_bg Page backgrounds
  57
  58     On Windows XP, the default theme paints a gradient on the notebook's pages.
  59     If you wish to suppress this theme, for aesthetic or performance reasons,
  60     there are three ways of doing it.
  61     You can use @c wxNB_NOPAGETHEME to disable themed drawing for a particular
  62     notebook, you can call wxSystemOptions::SetOption to disable it for the
  63     whole application, or you can disable it for individual pages by using
  64     SetBackgroundColour().
  65
  66     To disable themed pages globally:
  67     @code
  68     wxSystemOptions::SetOption("msw.notebook.themed-background", 0);
  69     @endcode
  70
  71     Set the value to 1 to enable it again.
  72     To give a single page a solid background that more or less fits in with the
  73     overall theme, use:
  74     @code
  75     wxColour col = notebook->GetThemeBackgroundColour();
  76     if (col.IsOk())
  77     {
  78         page->SetBackgroundColour(col);
  79     }
  80     @endcode
  81
  82     On platforms other than Windows, or if the application is not using Windows
  83     themes, GetThemeBackgroundColour() will return an uninitialised colour object,
  84     and the above code will therefore work on all platforms.
