    @class wxHtmlHelpWindow
    @headerfile helpwnd.h wx/html/helpwnd.h

    This class is used by wxHtmlHelpController
    to display help within a frame or dialog, but you can use it yourself to create
    an embedded HTML help window.

    For example:

    @code
    // m_embeddedHelpWindow is a wxHtmlHelpWindow
        // m_embeddedHtmlHelp is a wxHtmlHelpController

        // Create embedded HTML Help window
        m_embeddedHelpWindow = new wxHtmlHelpWindow;
        m_embeddedHtmlHelp.UseConfig(config, rootPath); // Set your own config
    object here
        m_embeddedHtmlHelp.SetHelpWindow(m_embeddedHelpWindow);
        m_embeddedHelpWindow-Create(this,
            wxID_ANY, wxDefaultPosition, GetClientSize(),
    wxTAB_TRAVERSAL|wxBORDER_NONE, wxHF_DEFAULT_STYLE);
        m_embeddedHtmlHelp.AddBook(wxFileName(_T("doc.zip")));
    @endcode

    You should pass the style wxHF_EMBEDDED to the style parameter of
    wxHtmlHelpController to allow
    the embedded window to be destroyed independently of the help controller.
