Method Details

stateChanged

public void stateChanged(ChangeEvent e)

Invoked when the target of the listener has changed its state.

Specified by:

stateChanged in interface ChangeListener

Parameters:

e - a ChangeEvent 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 interface PropertyChangeListener

Parameters:

e - A PropertyChangeEvent 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 class AccessibleContext

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 class AccessibleContext

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 class AccessibleContext

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 class AccessibleContext

Returns:

an instance of AccessibleStateSet containing the current state set of the object

See Also:

• AccessibleStateSet
• AccessibleState
• AccessibleContext.addPropertyChangeListener(java.beans.PropertyChangeListener)

getAccessibleParent

public Accessible getAccessibleParent()

Gets the Accessible parent of this object.

Overrides:

getAccessibleParent in class AccessibleContext

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 class AccessibleContext

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 class AccessibleContext

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 class AccessibleContext

Parameters:

i - zero-based index of child

Returns:

the Accessible child of the object

See Also:

• getAccessibleChildrenCount()

getLocale

public Locale getLocale()
                 throws IllegalComponentStateException

Gets the locale of the component. If the component does not have a locale, then the locale of its parent is returned.

Specified by:

getLocale in class AccessibleContext

Returns:

this component's locale. If this component does not have a locale, the locale of its parent is returned.

Throws:

IllegalComponentStateException - If the Component does not have its own locale and has not yet been added to a containment hierarchy such that the locale can be determined from the containing parent.

getAccessibleComponent

public AccessibleComponent getAccessibleComponent()

Gets the AccessibleComponent associated with this object that has a graphical representation.

Overrides:

getAccessibleComponent in class AccessibleContext

Returns:

AccessibleComponent if supported by object; else return null

See Also:

• AccessibleComponent

getAccessibleValue

public AccessibleValue getAccessibleValue()

Gets the AccessibleValue associated with this object that supports a Numerical value.

getAccessibleText in class AccessibleContext

Returns:

AccessibleText if supported by object; else return null

See Also:

• AccessibleText
