Defines a help manager used to display a help query or a table of contents.
Declaration
THelpManager = class(TObject)Inheritance
- THelpManager
- TObject
Descends from it: THelpDatabases
Description
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.
