- This is a family of classes by which applications may invoke a help viewer
- to provide on-line help.
+ This is the abstract base class a family of classes by which applications
+ may invoke a help viewer to provide on-line help.
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.
The help viewer will only get run, however, just before the first call to
display something.
- Most help controller classes actually derive from wxHelpControllerBase and have
- names of the form wxXXXHelpController or wxHelpControllerXXX.
- An appropriate class is aliased to the name wxHelpController for each platform, as
- follows:
- - On desktop Windows, wxCHMHelpController is used (MS HTML Help).
- - On Windows CE, wxWinceHelpController is used.
- - On all other platforms, wxHtmlHelpController is used if wxHTML is compiled
- into wxWidgets; otherwise wxExtHelpController is used (for invoking an
- external browser).
-
- The remaining help controller classes need to be named explicitly by an
- application that wishes to make use of them.
-
- The following help controller classes are defined:
- - wxWinHelpController, for controlling Windows Help.
- - wxCHMHelpController, for controlling MS HTML Help. To use this, you need to
- set wxUSE_MS_HTML_HELP to 1 in setup.h and have the htmlhelp.h header from
- Microsoft's HTML Help kit. (You don't need the VC++-specific htmlhelp.lib
- because wxWidgets loads necessary DLL at runtime and so it works with all
- compilers.)
- - wxBestHelpController, for controlling MS HTML Help or, if Microsoft's runtime
- is not available, wxHtmlHelpController. You need to provide @b both CHM and
- HTB versions of the help file. For wxMSW only.
- - wxExtHelpController, for controlling external browsers under Unix.
- The default browser is Netscape Navigator. The 'help' sample shows its use.
- - wxWinceHelpController, for controlling a simple @c .htm help controller for
- Windows CE applications.
- - wxHtmlHelpController, a sophisticated help controller using wxHTML, in a
- similar style to the Microsoft HTML Help viewer and using some of the same
- files. Although it has an API compatible with other help controllers, it has
- more advanced features, so it is recommended that you use the specific API
- for this class instead. Note that if you use .zip or .htb formats for your
- books, you must add this line to your application initialization:
- @code wxFileSystem::AddHandler(new wxArchiveFSHandler); @endcode
- or nothing will be shown in your help window.

+
+ This is an alias for one of a family of help controller classes which is
+ most appropriate for the current platform.
+
+ 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
+ user requests a different topic via the application's menus or buttons.
+
+ Typically, an application will create a help controller instance when it starts,
+ and immediately call wxHelpController::Initialize to associate a filename with it.
+ The help viewer will only get run, however, just before the first call to
+ display something.
+
+ Most help controller classes actually derive from wxHelpControllerBase and have
+ names of the form wxXXXHelpController or wxHelpControllerXXX.
+ An appropriate class is aliased to the name wxHelpController for each platform, as
+ follows:
