Specified by:

contentsChanged in interface ListDataListener

Parameters:

e - ListDataEvent

---

getAccessibleStateSet

public AccessibleStateSet getAccessibleStateSet()

Get the state set of this object.

Overrides:

getAccessibleStateSet in class JComponent.AccessibleJComponent

Returns:

an instance of AccessibleState containing the current state of the object

i - zero-based index of child

Returns:

the nth Accessible child of the object

---

getAccessibleSelection

public AccessibleSelection getAccessibleSelection()

Get the AccessibleSelection associated with this object if one exists. Otherwise return null.

Overrides:

getAccessibleSelection in class AccessibleContext

Tags copied from class: AccessibleContext

Returns:

AccessibleSelection if supported by object; else return null
