Description
THelpContents brings up the contents for the default help system.
Add THelpContents to an action list to allow users to bring up the help contents by using menu items or toolbar buttons. Controls such as menu items and tool buttons linked to this action cause the application to send the default help system a command to show the help contents.
In order for THelpContents to work and to call the proper native Help handling function, insert in the uses clause of your application the Vcl.HtmlHelpViewer unit or other unit providing interface to the external Help viewer to use. The Vcl.HtmlHelpViewer unit provides a Delphi interface to the HTMLHelp Windows native Help handling function. For C++, you need to include the HTMLHelpViewer.hpp header files.
For information about the native Help handling functions HTMLHelp or other and about the data passed to them, see the appropriate HTMLHelp topics in the MSDN Library.
