Naming Conventions in MacApp Code

Code in the MacApp class library and sample applications, as well as sample code used in this book, follows certain naming conventions:

• Each distinct word in the name of a variable, constant, or routine begins with an uppercase letter (for example, CloseAndFree).
• Names of variables and constants begin with a lowercase letter.
  • Global variable identifiers begin with a lowercase g (gConfiguration).
  • Command constants begin with a lowercase c (cUndo).
  • Other constants begin with a lowercase k (kWantHScrollBar).
  • Fields (also known as instance variables) of object classes begin with a lowercase f (fDocument).
  • Fields that are static global variables begin with a lowercase fg (fgDragDropSession).
  • Compile-time variables begin with a lowercase q (qDebug).

• All method names begin with an uppercase letter (Enable).
• Most of the classes in MacApp descend from TObject and begin with an uppercase T (for example, TApplication). Exceptions include
  • C++ utility classes (such as CIterator), which begin with an uppercase C
  • the mixin classes used for multiple inheritance (MScriptableObject), which begin with an uppercase M
  • a small number of memory and utility classes (BestFitBlock, PatchEventAvail), which do not have a common beginning character
