\section{\class{wxHtmlHelpWindow}}\label{wxhtmlhelpwindow}

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

For example:

\begin{verbatim}
    // 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")));
\end{verbatim}

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.

\section{\class{wxHtmlModalHelp}}\label{wxhtmlmodalhelp}

This class uses \helpref{wxHtmlHelpController}{wxhtmlhelpcontroller} 
to display help in a modal dialog. This is useful on platforms such as wxMac
where if you display help from a modal dialog, the help window must itself be a modal
dialog.

Create objects of this class on the stack, for example:

\begin{verbatim}
    // The help can be browsed during the lifetime of this object; when the user quits
    // the help, program execution will continue.
    wxHtmlModalHelp help(parent, wxT("help"), wxT("My topic"));
