### wxHtmlHelpFrame::wxHtmlHelpFrame

wxHtmlHelpFrame(wxHtmlHelpData* data = NULL)

wxHtmlHelpFrame(wxWindow* parent, int wxWindowID, const wxString& title = wxEmptyString, int style = wxHF_DEFAULT_STYLE, wxHtmlHelpData* data = NULL)

Constructor.

style is combination of these flags:

wxHF_ICONS_BOOK | All nodes in contents pane have a book icon. This is how Microsoft's HTML help viewer behaves.
wxHF_ICONS_FOLDER | Book nodes in contents pane have a book icon, book's sections have a folder icon. This is the default.
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.
wxHF_DEFAULT_STYLE | `wxHF_TOOLBAR | wxHF_CONTENTS | wxHF_INDEX | wxHF_SEARCH | wxHF_BOOKMARKS | wxHF_PRINT`

### wxHtmlHelpFrame::Create

2. try to open starting page of book x
3. try to find x in contents (if x is for example "How To ...")
4. try to find x in index (if x is for example "How To ...")
