Go Up to Help System Interfaces

The System.HelpIntfs.ICustomHelpViewer interface contains three types of methods:

Attention! The HelpIntfs unit does not provide an implementation for the ICustomHelpViewer interface. To use methods from ICustomHelpViewer, you can insert in the uses clause of your application the Vcl.HtmlHelpViewer unit. The Vcl.HtmlHelpViewer unit provides a Delphi interface to the HTMLHelp Windows native Help-handling function. For C++, you need to include the Vcl.HtmlHelpViewer.hpp header file. You can also provide your own implementation for ICustomHelpViewer. This implementation should provide a Delphi (or C++) wrapper to some external Help viewer to use.
