\section{\class{wxHtmlHelpFrame}}\label{wxhtmlhelpframe}

This class is used by \helpref{wxHtmlHelpController}{wxhtmlhelpcontroller} 
to display help.
It is an internal class and should not be used directly - except for the case
when you're writing your own HTML help controller.

\membersection{wxHtmlHelpFrame::wxHtmlHelpFrame}\label{wxhtmlhelpframewxhtmlhelpframe}

\func{}{wxHtmlHelpFrame}{\param{wxHtmlHelpData* }{data = NULL}}

\func{}{wxHtmlHelpFrame}{\param{wxWindow* }{parent}, \param{int }{wxWindowID}, \param{const wxString\& }{title = wxEmptyString}, \param{int }{style = wxHF\_DEFAULT\_STYLE}, \param{wxHtmlHelpData* }{data = NULL}}

Constructor.

{\it style} is combination of these flags:

\begin{twocollist}\itemsep=0pt
\twocolitem{\windowstyle{wxHF\_TOOLBAR}}{Help frame has toolbar.}
\twocolitem{\windowstyle{wxHF\_FLAT\_TOOLBAR}}{Help frame has toolbar with flat buttons (aka coolbar).}
\twocolitem{\windowstyle{wxHF\_CONTENTS}}{Help frame has contents panel.}
\twocolitem{\windowstyle{wxHF\_INDEX}}{Help frame has index panel.}
\twocolitem{\windowstyle{wxHF\_SEARCH}}{Help frame has search panel.}
\twocolitem{\windowstyle{wxHF\_BOOKMARKS}}{Help frame has bookmarks controls.}
\twocolitem{\windowstyle{wxHF\_OPEN\_FILES}}{Allow user to open arbitrary HTML document.}
\twocolitem{\windowstyle{wxHF\_PRINT}}{Toolbar contains "print" button.}
\twocolitem{\windowstyle{wxHF\_MERGE\_BOOKS}}{Contents pane does not show
book nodes. All books are merged together and appear as single book to the
user.}
\twocolitem{\windowstyle{wxHF\_ICONS\_BOOK}}{All nodes in contents pane
have a book icon. This is how Microsoft's HTML help viewer behaves.}
\twocolitem{\windowstyle{wxHF\_ICONS\_FOLDER}}{Book nodes in contents pane have
a book icon, book's sections have a folder icon. This is the default.}
\twocolitem{\windowstyle{wxHF\_ICONS\_BOOK\_CHAPTER}}{Both book nodes and
nodes of top-level sections of a book (i.e. chapters) have a book icon,
all other sections (sections, subsections, ...) have a folder icon.}
\twocolitem{\windowstyle{wxHF\_DEFAULT\_STYLE}}{{\tt wxHF\_TOOLBAR | wxHF\_CONTENTS
| wxHF\_INDEX | wxHF\_SEARCH | wxHF\_BOOKMARKS | wxHF\_PRINT}}
\end{twocollist}

\membersection{wxHtmlHelpFrame::Create}\label{wxhtmlhelpframecreate}

\func{bool}{Create}{\param{wxWindow* }{parent}, \param{wxWindowID }{id}, \param{const wxString\& }{title = wxEmptyString}, \param{int }{style = wxHF\_DEFAULT\_STYLE}}

Creates the frame. See \helpref{the constructor}{wxhtmlhelpframewxhtmlhelpframe}
for parameters description.

\membersection{wxHtmlHelpFrame::CreateContents}\label{wxhtmlhelpframecreatecontents}

\func{void}{CreateContents}{\param{bool }{show\_progress = FALSE}}

Creates contents panel. (May take some time.)

\membersection{wxHtmlHelpFrame::CreateIndex}\label{wxhtmlhelpframecreateindex}

\func{void}{CreateIndex}{\param{bool }{show\_progress = FALSE}}

Creates index panel. (May take some time.)

\membersection{wxHtmlHelpFrame::CreateSearch}\label{wxhtmlhelpframecreatesearch}

\func{void}{CreateSearch}{\void}

Creates search panel.

\membersection{wxHtmlHelpFrame::Display}\label{wxhtmlhelpframedisplay}

\func{bool}{Display}{\param{const wxString\& }{x}}

\func{bool}{Display}{\param{const int }{id}}

Displays page x. If not found it will give the user the choice of
searching books.
Looking for the page runs in these steps:

\begin{enumerate}\itemsep=0pt
\item try to locate file named x (if x is for example "doc/howto.htm")
\item try to open starting page of book x
\item try to find x in contents (if x is for example "How To ...")
\item try to find x in index (if x is for example "How To ...")
\end{enumerate}

The second form takes numeric ID as the parameter.
(uses extension to MS format, <param name="ID" value=id>)

\pythonnote{The second form of this method is named DisplayId in
wxPython.}
