    @class wxAuiNotebook

    wxAuiNotebook is part of the wxAUI class framework.
    See also @ref overview_aui.

    wxAuiNotebook is a notebook control which implements many features common in
    applications with dockable panes.
    Specifically, wxAuiNotebook implements functionality which allows the user to
    rearrange tab order via drag-and-drop, split the tab window into many different
    splitter configurations, and toggle through different themes to customize
    the control's look and feel.

    An effort has been made to try to maintain an API as similar to that of
    wxNotebook (note that wxAuiNotebook does not derive from wxNotebook!).

    The default theme that is used is wxAuiDefaultTabArt, which provides a modern,
    glossy look and feel.
    The theme can be changed by calling wxAuiNotebook::SetArtProvider.

    @style{wxAUI_NB_DEFAULT_STYLE}
           Defined as wxAUI_NB_TOP | wxAUI_NB_TAB_SPLIT | wxAUI_NB_TAB_MOVE |
           wxAUI_NB_SCROLL_BUTTONS | wxAUI_NB_CLOSE_ON_ACTIVE_TAB.
    @style{wxAUI_NB_TAB_SPLIT}
           Allows the tab control to be split by dragging a tab.
    @style{wxAUI_NB_TAB_MOVE}
           Allows a tab to be moved horizontally by dragging.
    @style{wxAUI_NB_TAB_EXTERNAL_MOVE}
           Allows a tab to be moved to another tab control.
    @style{wxAUI_NB_TAB_FIXED_WIDTH}
           With this style, all tabs have the same width.
    @style{wxAUI_NB_SCROLL_BUTTONS}
           With this style, left and right scroll buttons are displayed.
    @style{wxAUI_NB_WINDOWLIST_BUTTON}
           With this style, a drop-down list of windows is available.
    @style{wxAUI_NB_CLOSE_BUTTON}
           With this style, a close button is available on the tab bar.
    @style{wxAUI_NB_CLOSE_ON_ACTIVE_TAB}
           With this style, the close button is visible on the active tab.
    @style{wxAUI_NB_CLOSE_ON_ALL_TABS}
           With this style, the close button is visible on all tabs.
    @style{wxAUI_NB_TOP}
           With this style, tabs are drawn along the top of the notebook.
    @style{wxAUI_NB_BOTTOM}
           With this style, tabs are drawn along the bottom of the notebook.
