Here are the classes, structs, unions and interfaces with brief descriptions:

[detail level 12]

▼NAtk	The ATK interface which provides standard mechanism for manipulating hyperlinks
CAction	The ATK interface provided by UI components which the user can activate/interact with, This should be implemented by instances of Atk::Object classes with which the user can interact directly, i.e
CAttribute
CAttributeTraits
CComponent	The ATK interface provided by UI components which occupy a physical area on the screen
CDocument	The ATK interface which allows access to a DOM associated with on object
CEditableText	The ATK interface implemented by components containing user-editable text content
CHyperlink	Encapsulates a link or set of links in a hypertext document
CHypertext
CImage	The ATK Interface implemented by components which expose image or pixmap content on-screen
CImplementor
CNoOpObject	An Atk::NoOpObject is an Atk::Object which purports to implement all ATK interfaces
CObject	The base object class for the Accessibility Toolkit API
CObjectAccessible	This object class is derived from AtkObject and can be used as a basis implementing accessible objects
CRange	A given range or subrange, to be used with Atk::Value
CRelation	An Atk::Relation describes a relation between an object and one or more other objects
CRelationSet	A set of Atk::Relations, normally the set of AtkRelations which an Atk::Object has
CSelection	The ATK interface implemented by container objects whose Atk::Object children can be selected
CStateSet	An AtkStateSet determines a component's state set
CStreamableContent	The ATK interface which provides access to streamable content
CTable	The ATK interface implemented for UI components which contain tabular or row/column information
CText	The ATK interface implemented by components with text content
CTextAttribute
CValue	The ATK interface implemented by valuators and components which display or select a value from a bounded range of values
