  10     @class wxHtmlHelpWindow
  11
  12     This class is used by wxHtmlHelpController to display help within a frame or
  13     dialog, but you can use it yourself to create an embedded HTML help window.
  14
  15     For example:
  16     @code
  17         // m_embeddedHelpWindow is a wxHtmlHelpWindow
  18         // m_embeddedHtmlHelp is a wxHtmlHelpController
  19
  20         // Create embedded HTML Help window
  21         m_embeddedHelpWindow = new wxHtmlHelpWindow;
  22         m_embeddedHtmlHelp.UseConfig(config, rootPath); // Set your own config object here
  23         m_embeddedHtmlHelp.SetHelpWindow(m_embeddedHelpWindow);
  24         m_embeddedHelpWindow->Create(this, wxID_ANY, wxDefaultPosition, GetClientSize(),
  25                                      wxTAB_TRAVERSAL|wxBORDER_NONE, wxHF_DEFAULT_STYLE);
  26         m_embeddedHtmlHelp.AddBook(wxFileName(wxT("doc.zip")));
  27     @endcode
  28
  29     You should pass the style wxHF_EMBEDDED to the style parameter of
  30     wxHtmlHelpController to allow the embedded window to be destroyed
  31     independently of the help controller.
