Interface AccessibleKeyBinding
public interface AccessibleKeyBinding
The AccessibleKeyBinding interface should be supported by any object
that has a keyboard bindings such as a keyboard mnemonic and/or keyboard
shortcut which can be used to select the object. This interface provides
the standard mechanism for an assistive technology to determine the
key bindings which exist for this object.
Any object that has such key bindings should support this
interface. Applications can determine if an object supports the
AccessibleKeyBinding interface by first obtaining its AccessibleContext
(see @link Accessible} and then calling the
AccessibleContext#getAccessibleKeyBinding method. If the return
value is not null, the object supports this interface.

getAccessibleKeyBindingCount
int getAccessibleKeyBindingCount()
- Returns the number of key bindings for this object
- Returns:
- the zero-based number of key bindings for this object
getAccessibleKeyBinding
Object getAccessibleKeyBinding(int i)
- Returns a key binding for this object. The value returned is an
java.lang.Object which must be cast to appropriate type depending
on the underlying implementation of the key. For example, if the
Object returned is a javax.swing.KeyStroke, the user of this
method should do the following:
Component c =
AccessibleContext ac = c.getAccessibleContext();
AccessibleKeyBinding akb = ac.getAccessibleKeyBinding();
for (int i = 0; i < akb.getAccessibleKeyBindingCount(); i++) {
Object o = akb.getAccessibleKeyBinding(i);
if (o instanceof javax.swing.KeyStroke) {
javax.swing.KeyStroke keyStroke = (javax.swing.KeyStroke)o;
}
}
- Parameters:
i - zero-based index of the key bindings
- Returns:
- a javax.lang.Object which specifies the key binding
