Description
THelpTopicSearch brings up the help index.
Add THelpTopicSearch to an action list to allow users to bring up the help index. Controls such as menu items and tool buttons linked to this action cause the application to send the default help system a command to display the help index.
In order for THelpTopicSearch 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.
