This class implements accessibility support for theJComboBoxclass. 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.beanspackage. Please seeXMLEncoder.- See Also:

Method Detail
-
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:
getAccessibleChildrenCountin classJComponent.AccessibleJComponent- Returns:
- the number of accessible children in the object.
-
getAccessibleChild
public Accessible getAccessibleChild(int i)
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:
getAccessibleChildin classJComponent.AccessibleJComponent- Parameters:
i- zero-based index of child- Returns:
- the nth Accessible child of the object
- See Also:
AccessibleContext.getAccessibleChildrenCount()
-
getAccessibleRole
public AccessibleRole getAccessibleRole()
Get the role of this object.- Overrides:
getAccessibleRolein classJComponent.AccessibleJComponent- Returns:
- an instance of AccessibleRole describing the role of the object
- See Also:
AccessibleRole
-
getAccessibleStateSet
public AccessibleStateSet getAccessibleStateSet()
Gets the state set of this object. The AccessibleStateSet of an object is composed of a set of unique AccessibleStates. A change in the AccessibleStateSet of an object will cause a PropertyChangeEvent to be fired for the ACCESSIBLE_STATE_PROPERTY property.- Overrides:
getAccessibleStateSetin classJComponent.AccessibleJComponent- Returns:
- an instance of AccessibleStateSet containing the current state set of the object
- See Also:
AccessibleStateSet,AccessibleState,JComponent.AccessibleJComponent.addPropertyChangeListener(java.beans.PropertyChangeListener)
-
getAccessibleAction
public AccessibleAction getAccessibleAction()
Get the AccessibleAction associated with this object. In the implementation of the Java Accessibility API for this class, return this object, which is responsible for implementing the AccessibleAction interface on behalf of itself.- Overrides:
getAccessibleActionin classAccessibleContext- Returns:
- this object
- See Also:
AccessibleAction
-
getAccessibleActionDescription
public String getAccessibleActionDescription(int i)
Return a description of the specified action of the object.- Specified by:
getAccessibleActionDescriptionin interfaceAccessibleAction- Parameters:
i- zero-based index of the actions- Returns:
- a
Stringdescription of the action - See Also:
AccessibleAction.getAccessibleActionCount()
-
getAccessibleActionCount
public int getAccessibleActionCount()
Returns the number of Actions available in this object. The default behavior of a combo box is to have one action.- Specified by:
getAccessibleActionCountin interfaceAccessibleAction- Returns:
- 1, the number of Actions in this object
-
doAccessibleAction
public boolean doAccessibleAction(int i)
Perform the specified Action on the object- Specified by:
doAccessibleActionin interfaceAccessibleAction- Parameters:
i- zero-based index of actions- Returns:
- true if the action was performed; else false.
- See Also:
AccessibleAction.getAccessibleActionCount()
-
getAccessibleSelection
public AccessibleSelection getAccessibleSelection()
Get the AccessibleSelection associated with this object. In the implementation of the Java Accessibility API for this class, return this object, which is responsible for implementing the AccessibleSelection interface on behalf of itself.- Overrides:
getAccessibleSelectionin classAccessibleContext- Returns:
- this object
- See Also:
AccessibleSelection
-
getAccessibleSelectionCount
public int getAccessibleSelectionCount()
Returns the number of Accessible children currently selected. If no children are selected, the return value will be 0.- Specified by:
getAccessibleSelectionCountin interfaceAccessibleSelection- Returns:
- the number of items currently selected.
- Since:
- 1.3
-
getAccessibleSelection
public Accessible getAccessibleSelection(int i)
Returns an Accessible representing the specified selected child in the popup. If there isn't a selection, or there are fewer children selected than the integer passed in, the return value will be null.Note that the index represents the i-th selected child, which is different from the i-th child.
- Specified by:
getAccessibleSelectionin interfaceAccessibleSelection- Parameters:
i- the zero-based index of selected children- Returns:
- the i-th selected child
- Since:
- 1.3
- See Also:
getAccessibleSelectionCount()
-
isAccessibleChildSelected
public boolean isAccessibleChildSelected(int i)
Determines if the current child of this object is selected.- Specified by:
isAccessibleChildSelectedin interfaceAccessibleSelection- Parameters:
i- the zero-based index of the child in this Accessible object.- Returns:
- true if the current child of this object is selected; else false
- Since:
- 1.3
- See Also:
AccessibleContext.getAccessibleChild(int)
-
addAccessibleSelection
public void addAccessibleSelection(int i)
Adds the specified Accessible child of the object to the object's selection. If the object supports multiple selections, the specified child is added to any existing selection, otherwise it replaces any existing selection in the object. If the specified child is already selected, this method has no effect.- Specified by:
addAccessibleSelectionin interfaceAccessibleSelection- Parameters:
i- the zero-based index of the child- Since:
- 1.3
- See Also:
AccessibleContext.getAccessibleChild(int)
-
removeAccessibleSelection
public void removeAccessibleSelection(int i)
