javax.accessibility: Javadoc index of package javax.accessibility.


Package Samples:

javax.accessibility

Classes:

AccessibleContext: The minimum information that all accessible objects return. This includes name, description, role, and state of the object, parents and children, and any other useful information. If a component supports further details, it should implement one of the following: AccessibleAction - the object can perform actions AccessibleComponent - the object has a graphical representation AccessibleSelection - the object allows its children to be selected AccessibleText - the object represents editable text AccessibleValue - the object represents a numerical value
AccessibleValue: If an object implements this interface then it must be able to control a numerical value. For example, a scroll bar has a position represented by a number. Accessibility software can use the implementations of this interface to change the associated value. The AccessibleContext.getAccessibleValue() method should return null if an object does not implement this interface.
AccessibleComponent: Objects which are to be rendered to a screen as part of a graphical user interface should implement this interface. Accessibility software can use the implementations of this interface to determine and set the screen representation for an object. The AccessibleContext.getAccessibleComponent() method should return null if an object does not implement this interface.
AccessibleEditableText: Objects which present editable textual information on the display should implement this interface. Accessibility software can use the implementations of this interface to change the content, attributes, and spacial location of the text. The AccessibleContext.getAccessibleEditableText() method should return null if an object does not implement this interface.
AccessibleExtendedComponent: Objects which present graphical components with extensions such as key bindings or tool-tips should implement this interface. Accessibility software can use the implementations of this interface to display the extended information of the component. The AccessibleContext.getAccessibleComponent() method should return an instance of this interface only when it is supported.
AccessibleState: A state portion of an accessible object. A combination of states represent the entire object state, in an AccessibleStateSet. For example, this could be "active" or "selected". This strongly typed "enumeration" supports localized strings. If the constants of this class are not adequate, new ones may be added in a similar matter, while avoiding a public constructor.
AccessibleText: Objects which present textual information on the display should implement this interface. Accessibility software can use the implementations of this interface to change the attributes and spacial location of the text. The AccessibleContext.getAccessibleText() method should return null if an object does not implement this interface.
AccessibleKeyBinding: Objects which have keyboard bindings for mneumonics or shortcuts should implement this interface. Accessibility software can use the implementations of this interface to aid the user in using the key bindings. The AccessibleContext.getAccessibleKeyBinding() method should return null if an object does not implement this interface.
AccessibleSelection: If an object implements this interface then it must be able to control the selection of its children. Accessibility software can use the implementations of this interface to change the selection set of children. The AccessibleContext.getAccessibleSelection() method should return null if an object does not implement this interface.
AccessibleTable: Objects which present information in a 2-dimensional table should implement this interface. Accessibility software can use the implementations of this interface to navigate and change the attributes of the table. The AccessibleContext.getAccessibleTable() method should return null if an object does not implement this interface.
AccessibleAction: If an object implements this interface then it must be able to perform one or more actions. Accessibility software can use the implementations of this interface to discover and perform actions on an object. The AccessibleContext.getAccessibleAction() method should return null if an object does not implement this interface.
AccessibleExtendedTable: Objects which present 2-D tables with the extension of a flat address space should implement this interface. Accessibility software can use the implementations of this interface to better manipulate the table. The AccessibleContext.getAccessibleTable() method should return an instance of this interface only when it is supported.
AccessibleIcon: Objects which have an associated icon, such as buttons, should implement this interface. Accessibility software can use the implementations of this interface to aid the user in navigating the links. The AccessibleContext.getAccessibleIcon() method should return null if an object does not implement this interface.
AccessibleRelation: The relation between one accessible object and one or more other objects. For example, a button may control an action. An AccessibleRelationSet summarizes all relations of the object. This strongly typed "enumeration" supports localized strings. If the constants of this class are not adequate, new ones may be added in a similar matter.
AccessibleHypertext: Objects which present hyperlinks in a document should implement this interface. Accessibility software can use the implementations of this interface to aid the user in navigating the links. The AccessibleContext.getAccessibleText() method should return an instance of this interface only when it is supported.
AccessibleRole: The role of an accessible object. For example, this could be "button" or "table". This strongly typed "enumeration" supports localized strings. If the constants of this class are not adequate, new ones may be added in a similar matter, while avoiding a public constructor.
Accessible: Implementing the Accessibility API must start with implementation of this interface at a bare minimum. This is the major interface for the Accessibility API which must be implemented by all user interface components.
AccessibleBundle: This serves as a base class for accessibility "enumerations". These objects are strongly typed; to make up for the lack of true enums in Java. Display should be locale dependent.
AccessibleTableModelChange: Describes a change to an accessible table. Accessibility software can use the implementations of this interface to update their state after a change to a table.
AccessibleResourceBundle: This class is deprecated. It once was used for localizing accessibility strings, and was never meant for external use anyway.
AccessibleRelationSet: Describes all relations of an accessible object. For example, an object by labeled by one object and control another.
AccessibleStateSet: Describes all elements of an accessible object's state. For example, an object may be enabled and have focus.
AccessibleExtendedText: This interface provides extended text functionality, similar to AccessibleText.
AccessibleAttributeSequence: This is a convenience class that represents an accessible attribute sequence.
AccessibleHyperlink: This object encapsulates actions associated with navigating hypertext.
