-This class defines the interface by which
+This is a family of classes by which
applications may invoke a help viewer to provide on-line help.
-Other classes derive from this class to provide actual implementations
-of help controllers.
-
A help controller allows an application to display help, at the contents
or at a particular topic, and shut the help program down on termination.
This avoids proliferation of many instances of the help viewer whenever the
to associate a filename with it. The help viewer will only get run, however,
just before the first call to display something.

-\helpref{wxObject}{wxobject}
+Although all help controller classes actually derive from wxHelpControllerBase and have
+names of the form wxXXXHelpController, the
+appropriate class is aliased to the name wxHelpController for each platform.
-\wxheading{See also}
+There are currently the following help controller classes defined:

+\begin{itemize}\itemsep=0
+\item wxWinHelpController, for controlling Windows Help.
+\item wxExtHelpController, for controlling external browsers under Unix.
+The default browser is Netscape Navigator.

-\membersection{wxHelpControllerBase::wxHelpControllerBase}
+\membersection{wxHelpController::wxHelpController}
-\func{}{wxHelpControllerBase}{\void}
+\func{}{wxHelpController}{\void}
Constructs a help instance object, but does not invoke the help viewer.
-\membersection{wxHelpControllerBase::\destruct{wxHelpControllerBase}}
+\membersection{wxHelpController::\destruct{wxHelpController}}
-\func{}{\destruct{wxHelpControllerBase}}{\void}
+\func{}{\destruct{wxHelpController}}{\void}
Destroys the help instance, closing down the viewer if it is running.
-\membersection{wxHelpControllerBase::Initialize}\label{wxhelpcontrollerbaseinitialize}
+\membersection{wxHelpController::Initialize}\label{wxhelpcontrollerinitialize}
\func{virtual void}{Initialize}{\param{const wxString\& }{file}}
You may omit the file extension and a suitable one will be chosen.
-\membersection{wxHelpControllerBase::DisplayBlock}\label{wxhelpcontrollerbasedisplayblock}
+\membersection{wxHelpController::DisplayBlock}\label{wxhelpcontrollerdisplayblock}
\func{virtual bool}{DisplayBlock}{\param{long}{ blockNo}}
The interpretation of {\it blockNo} differs between help viewers. If using Windows Help, this
refers to the context number. If wxHelp, this is the wxHelp block number.
-\membersection{wxHelpControllerBase::DisplayContents}\label{wxhelpcontrollerbasedisplaycontents}
+\membersection{wxHelpController::DisplayContents}\label{wxhelpcontrollerdisplaycontents}
\func{virtual bool}{DisplayContents}{\void}
If the help viewer is not running, runs it and displays the
contents.
-\membersection{wxHelpControllerBase::DisplaySection}\label{wxhelpcontrollerbasedisplaysection}
+\membersection{wxHelpController::DisplaySection}\label{wxhelpcontrollerdisplaysection}
\func{virtual bool}{DisplaySection}{\param{int}{ sectionNo}}
DisplaySection does not apply to WinHelp.
-\membersection{wxHelpControllerBase::KeywordSearch}\label{wxhelpcontrollerbasekeywordsearch}
+\membersection{wxHelpController::KeywordSearch}\label{wxhelpcontrollerkeywordsearch}
\func{virtual bool}{KeywordSearch}{\param{const wxString\& }{keyWord}}
match is found, the Search dialog is displayed with the matches (wxHelp)
or the first topic is displayed (Windows Help).
-\membersection{wxHelpControllerBase::LoadFile}\label{wxhelpcontrollerbaseloadfile}
+\membersection{wxHelpController::LoadFile}\label{wxhelpcontrollerloadfile}
\func{virtual bool}{LoadFile}{\param{const wxString\& }{file = NULL}}
member function may be used before each display call in case the user
has opened another file.
-\membersection{wxHelpControllerBase::OnQuit}\label{wxhelpcontrollerbaseonquit}
+\membersection{wxHelpController::OnQuit}\label{wxhelpcontrolleronquit}
\func{virtual bool}{OnQuit}{\void}
Overridable member called when this application's viewer is quit by the user.
-This only works for wxXLPHelpController.
+This does not work for all help controllers.
-\membersection{wxHelpControllerBase::Quit}\label{wxhelpcontrollerbasequit}
