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 | 
| 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 | 
| CAttribute |  | 
| CAttributeTraits |  | 
| CTextAttribute |  | 
| CText | The ATK interface implemented by components with text content | 
| CValue | The ATK interface implemented by valuators and components which display or select a value from a bounded range of values |
