Methods
stateChanged
public void stateChanged(ChangeEvent e)
Invoked when the target of the listener has changed its state.
- Specified by:
-
stateChanged
in interfaceChangeListener
- Parameters:
-
e
- aChangeEvent
object. Must not be null. - Throws:
-
NullPointerException
- if the parameter is null.
propertyChange
public void propertyChange(PropertyChangeEvent e)
This method gets called when a bound property is changed.
- Specified by:
-
propertyChange
in interfacePropertyChangeListener
- Parameters:
-
e
- APropertyChangeEvent
object describing the event source and the property that has changed. Must not be null. - Throws:
-
NullPointerException
- if the parameter is null.
getAccessibleName
public String getAccessibleName()
Gets the accessibleName property of this object. The accessibleName property of an object is a localized String that designates the purpose of the object. For example, the accessibleName property of a label or button might be the text of the label or button itself. In the case of an object that doesn't display its name, the accessibleName should still be set. For example, in the case of a text field used to enter the name of a city, the accessibleName for the en_US locale could be 'city.'
- Overrides:
-
getAccessibleName
in classAccessibleContext
- Returns:
- the localized name of the object; null if this object does not have a name
- See Also:
AccessibleContext.setAccessibleName(java.lang.String)
getAccessibleDescription
public String getAccessibleDescription()
Gets the accessibleDescription property of this object. The accessibleDescription property of this object is a short localized phrase describing the purpose of the object. For example, in the case of a 'Cancel' button, the accessibleDescription could be 'Ignore changes and close dialog box.'
- Overrides:
-
getAccessibleDescription
in classAccessibleContext
- Returns:
- the localized description of the object; null if this object does not have a description
- See Also:
AccessibleContext.setAccessibleDescription(java.lang.String)
getAccessibleRole
public AccessibleRole getAccessibleRole()
Gets the role of this object. The role of the object is the generic purpose or use of the class of this object. For example, the role of a push button is AccessibleRole.PUSH_BUTTON. The roles in AccessibleRole are provided so component developers can pick from a set of predefined roles. This enables assistive technologies to provide a consistent interface to various tweaked subclasses of components (e.g., use AccessibleRole.PUSH_BUTTON for all components that act like a push button) as well as distinguish between subclasses that behave differently (e.g., AccessibleRole.CHECK_BOX for check boxes and AccessibleRole.RADIO_BUTTON for radio buttons).
Note that the AccessibleRole class is also extensible, so custom component developers can define their own AccessibleRole's if the set of predefined roles is inadequate.
- Specified by:
-
getAccessibleRole
in classAccessibleContext
- 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.
- Specified by:
-
getAccessibleStateSet
in classAccessibleContext
- Returns:
- an instance of AccessibleStateSet containing the current state set of the object
- See Also:
-
AccessibleStateSet

getAccessibleParent
in classAccessibleContext
- Returns:
- the Accessible parent of this object; null if this object does not have an Accessible parent
getAccessibleIndexInParent
public int getAccessibleIndexInParent()
Gets the 0-based index of this object in its accessible parent.
- Specified by:
-
getAccessibleIndexInParent
in classAccessibleContext
- Returns:
- the 0-based index of this object in its parent; -1 if this object does not have an accessible parent.
- See Also:
-
getAccessibleParent()
,getAccessibleChildrenCount()
,getAccessibleChild(int)
getAccessibleChildrenCount
public int getAccessibleChildrenCount()
Returns the number of accessible children of the object.
- Specified by:
-
getAccessibleChildrenCount
in classAccessibleContext
- Returns:
- the number of accessible children of the object.
getAccessibleChild
public Accessible getAccessibleChild(int i)
Returns the specified Accessible child of the object. The Accessible children of an Accessible object are zero-based, so the first child of an Accessible child is at index 0, the second child is at index 1, and so on.
- Specified by:
-
getAccessibleChild
in classAccessibleContext
- Parameters:
-
i
- zero-based index of child - Returns:
- the Accessible child of the object
- See Also:
getAccessibleChildrenCount()
