Constructor Details

AccessibleJListChild

public AccessibleJListChild(JList<E> parent, int indexInParent)

Constructs an AccessibleJListChild.

Parameters:: parent - the parent; indexInParent - the index in the parent

Method Details

getAccessibleContext

public AccessibleContext getAccessibleContext()

Get the AccessibleContext for this object. In the implementation of the Java Accessibility API for this class, returns this object, which is its own AccessibleContext.

Specified by:: getAccessibleContext in interface Accessible
Returns:: this object

setAccessibleName

public void setAccessibleName(String s)

Description copied from class: AccessibleContext

Sets the localized accessible name of this object. Changing the name will cause a PropertyChangeEvent to be fired for the ACCESSIBLE_NAME_PROPERTY property.

Overrides:

setAccessibleName in class AccessibleContext

Parameters:

s - the new localized name of the object

See Also:

setAccessibleDescription

public void setAccessibleDescription(String s)

Description copied from class: AccessibleContext

Sets the accessible description of this object. Changing the name will cause a PropertyChangeEvent to be fired for the ACCESSIBLE_DESCRIPTION_PROPERTY property.

Overrides:

See Also:

getAccessibleRole

public AccessibleRole getAccessibleRole()

Description copied from class: AccessibleContext

Gets the role of this object. The role of the object is the generic purpose or use of the class of this object. For example, the role of a push button is AccessibleRole.PUSH_BUTTON. The roles in AccessibleRole are provided so component developers can pick from a set of predefined roles. This enables assistive technologies to provide a consistent interface to various tweaked subclasses of components (e.g., use AccessibleRole.PUSH_BUTTON for all components that act like a push button) as well as distinguish between subclasses that behave differently (e.g., AccessibleRole.CHECK_BOX for check boxes and AccessibleRole.RADIO_BUTTON for radio buttons).

Note that the AccessibleRole class is also extensible, so custom component developers can define their own AccessibleRole's if the set of predefined roles is inadequate.

getAccessibleRole in class AccessibleContext

Returns:

an instance of AccessibleRole describing the role of the object

See Also:

getAccessibleStateSet

public AccessibleStateSet getAccessibleStateSet()

Specified by:

getAccessibleStateSet in class AccessibleContext

Returns:

an instance of AccessibleStateSet containing the current state set of the object

See Also:
