\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.}

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

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