## Detailed Description

The ATK interface which provides standard mechanism for manipulating hyperlinks.

## Classes
class | Action
| 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. More...
class | Attribute
struct | AttributeTraits
class | Component
| The ATK interface provided by UI components which occupy a physical area on the screen. More...
class | Document
| The ATK interface which allows access to a DOM associated with on object. More...

class | Hyperlink
class | Hypertext
class | Image
| The ATK Interface implemented by components which expose image or pixmap content on-screen. More...
class | Implementor
class | NoOpObject
| An Atk::NoOpObject is an Atk::Object which purports to implement all ATK interfaces. More...
class | Object
| The base object class for the Accessibility Toolkit API. More...
class | ObjectAccessible
| This object class is derived from AtkObject and can be used as a basis implementing accessible objects. More...
class | Relation
| An Atk::Relation describes a relation between an object and one or more other objects. More...
class | RelationSet
| A set of Atk::Relations, normally the set of AtkRelations which an Atk::Object has. More...
class | Selection
| The ATK interface implemented by container objects whose Atk::Object children can be selected. More...
class | StateSet
| An AtkStateSet determines a component's state set. More...
class | StreamableContent
| The ATK interface which provides access to streamable content. More...
class | Table
| The ATK interface implemented for UI components which contain tabular or row/column information. More...
class | Text
| The ATK interface implemented by components with text content. More...
class | TextAttribute
class | Value
| The ATK interface implemented by valuators and components which display or select a value from a bounded range of values. More...
