Interface AccessibleAction
- All Known Implementing Classes:
- AbstractButton.AccessibleAbstractButton, AccessibleHyperlink, Button.AccessibleAWTButton, Checkbox.AccessibleAWTCheckbox, CheckboxMenuItem.AccessibleAWTCheckboxMenuItem, Choice.AccessibleAWTChoice, JComboBox.AccessibleJComboBox, JTextComponent.AccessibleJTextComponent, JTree.AccessibleJTree.AccessibleJTreeNode, MenuItem.AccessibleAWTMenuItem
- public interface AccessibleAction
The AccessibleAction interface should be supported by any object
that can perform one or more actions. This interface
provides the standard mechanism for an assistive technology to determine
what those actions are as well as tell the object to perform them.
Any object that can be manipulated should support this
interface. Applications can determine if an object supports the
AccessibleAction interface by first obtaining its AccessibleContext (see
Accessible ) and then calling the AccessibleContext.getAccessibleAction()
method. If the return value is not null, the object supports this interface.
