Constructs an AccessibleJListChild.

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

Method Detail

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

getAccessibleComponent

public AccessibleComponent getAccessibleComponent()

Get the AccessibleComponent associated with this object. In the implementation of the Java Accessibility API for this class, return this object, which is responsible for implementing the AccessibleComponent interface on behalf of itself.

Overrides:
getAccessibleComponent in class AccessibleContext
Returns:
this object

getAccessibleIcon

public AccessibleIcon[] getAccessibleIcon()

Returns the icon for the element renderer, as the only item of an array of AccessibleIcons or a null array if the renderer component contains no icons.

Overrides:
getAccessibleIcon in class AccessibleContext
Returns:
an array containing the accessible icon or a null array if none

getAccessibleAction

public AccessibleAction getAccessibleAction()

Gets the AccessibleAction associated with this object that supports one or more actions.

Overrides:
getAccessibleAction in class AccessibleContext
Implementation Requirements:
Returns the AccessibleAction for this AccessibleJListChild as follows: First getListCellRendererComponent of the ListCellRenderer for the component at the "index in parent" of this child is called. Then its AccessibleContext is fetched and that AccessibleContext's AccessibleAction is returned. Note that if an AccessibleAction is not found using this process then this object with its implementation of the AccessibleAction interface is returned.
Returns:
AccessibleAction if supported by object; else return null

doAccessibleAction

public boolean doAccessibleAction​(int i)

Performs the specified action on the object.

Specified by:
doAccessibleAction in interface AccessibleAction
Implementation Requirements:
If i == 0 selects this AccessibleJListChild by calling JList.this.setSelectedIndex(indexInParent) and then returns true; otherwise returns false.
Parameters:
i - zero-based index of actions
Returns:
true if the action was performed; otherwise false
