Using Help in a CLX Application

The following sections explain how to use Help within a CLX application.

  1. How TApplication processes CLX Help
  2. How CLX controls process Help
  3. Calling a Help system directly
  4. Using IHelpSystem

How TApplication processes CLX Help

TApplication in CLX provides two methods that are accessible from application code:

ContextHelp, which invokes the Help system with a request for context-based Help
KeywordHelp, which invokes the Help system with a request for keyword-based Help

Both functions take as an argument the context or keyword being passed and forward the request on through a data member of TApplication, which represents the Help system. That data member is directly accessible through the read-only property HelpSystem.
