  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. Do not
  17     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.
