GEOS SDK Documentation: System Object Classes

Up: GEOS SDK TechDocs

The following documents describe GEOS object classes which are low-level. Most programmers will not have much use for the low-level mechanisms described in these documents.

GenClass
The ancestor of all generic UI object classes.
MetaClass
The ancestor of all object classes.
Input
How keyboard input finds its way to the intended object; mouse- and pen-input is discussed for those devices which support such.
GenProcessClass
All applications subclass GenProcessClass; all applications must. Few will alter the class' behavior; this chapter describes that behavior.
ProcessClass
Manages a thread.
GenApplicationClass
Ancestor class of the Nokia 9000i Communicator-enhanced FoamSubApplicationClass.
Clipboard
The mechanisms behind copy, paste, and quick-transfer.
GenDisplay
The object class underlying floating windows.
Generic UI Controllers
What you need to know to write a custom controller class.
