Examples of javax.accessibility.AccessibleContext

javax.accessibility.AccessibleContext
AccessibleContext represents the minimum information all accessible objects return. This information includes the accessible name, description, role, and state of the object, as well as information about its parent and children. AccessibleContext also contains methods for obtaining more specific accessibility information about a component. If the component supports them, these methods will return an object that implements one or more of the following interfaces:
- {@link AccessibleAction} - the object can perform one or more actions.This interface provides the standard mechanism for an assistive technology to determine what those actions are and tell the object to perform them. Any object that can be manipulated should support this interface.
- {@link AccessibleComponent} - the object has a graphical representation.This interface provides the standard mechanism for an assistive technology to determine and set the graphical representation of the object. Any object that is rendered on the screen should support this interface.
- {@link AccessibleSelection} - the object allows its children to beselected. This interface provides the standard mechanism for an assistive technology to determine the currently selected children of the object as well as modify its selection set. Any object that has children that can be selected should support this interface.
- {@link AccessibleText} - the object presents editable textual informationon the display. This interface provides the standard mechanism for an assistive technology to access that text via its content, attributes, and spatial location. Any object that contains editable text should support this interface.
- {@link AccessibleValue} - the object supports a numerical value. Thisinterface provides the standard mechanism for an assistive technology to determine and set the current value of the object, as well as obtain its minimum and maximum values. Any object that supports a numerical value should support this interface.
