This class implements accessibility support for the
JComboBox
class. It provides an implementation of the
Java Accessibility API appropriate to Combo Box user-interface elements.
Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running
the same version of Swing. As of 1.4, support for long term storage
of all JavaBeans
has been added to the java.beans
package.

getAccessibleChildrenCount
public int getAccessibleChildrenCount()Returns the number of accessible children in the object. If all of the children of this object implement Accessible, than this method should return the number of children of this object.- Overrides:
getAccessibleChildrenCount
in classJComponent.AccessibleJComponent
- Returns:
- the number of accessible children in the object.
-
getAccessibleChild
Returns the nth Accessible child of the object. The child at index zero represents the popup. If the combo box is editable, the child at index one represents the editor.- Overrides:

getAccessibleRole
in classJComponent.AccessibleJComponent
- Returns:
- an instance of AccessibleRole describing the role of the object
- See Also:

getAccessibleStateSet
in classJComponent.AccessibleJComponent
- Returns:
- an instance of AccessibleStateSet containing the current state set of the object
- See Also:
-
getAccessibleAction
