Abstract Class Members
Go Up to Object-oriented programming for component writers Index
When a method is declared as abstract in an ancestor class, you should surface it (by redeclaring and implementing it) in any descendant component before you use the new component in applications. On the Win32 platform, Delphi can create instances of a class that contains abstract members. This is not recommended, however. For more information about surfacing inherited parts of classes, see Creating Properties - Overview and Creating Methods - Overview
