TObject |
THelpManager is a TObject descendant which defines a help manager. It provides methods used to display help for specific help query types, or a help table of contents. It also provides methods used to display/handle error messages.
On its own, THelpManager is not particulary useful. All of the methods return the shrHelpNotFound help result. They are, however, declared as abstract/virtual and should be implemented/overridden in a descendent class which provides support for a specific help format like HTML, CHM, INF, or other content type.
|
Implements support for accessing and maintaining registered help database classes in the help system. |
