Field Details

accessibleContainerHandler

protected ContainerListener accessibleContainerHandler
Receives notification when a child component is added to the JComponent and fires a PropertyChangeEvent on listeners registered with the AccessibleJComponent.

accessibleFocusHandler

protected FocusListener accessibleFocusHandler
Receives notification if the focus on the JComponent changes and fires appropriate PropertyChangeEvents to listeners registered with the AccessibleJComponent.

Constructor Details

AccessibleJComponent

protected AccessibleJComponent()
Creates a new AccessibleJComponent.

Method Details

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)
Adds a property change listener to the list of registered listeners. This sets up the accessibleContainerHandler and accessibleFocusHandler fields and calls super.addPropertyChangeListener(listener).
Overrides:
addPropertyChangeListener in interface Component.AccessibleAWTComponent
Parameters:
listener - the listener to add

getAccessibleChild

public Accessible getAccessibleChild(int i)
Returns the accessible child component at index i.
Overrides:
getAccessibleChild in interface Container.AccessibleAWTContainer
Parameters:
i - the index of the accessible child to return
Returns:
the accessible child component at index i

getAccessibleChildrenCount

public int getAccessibleChildrenCount()
Returns the number of accessible children of this object.
Overrides:
getAccessibleChildrenCount in interface Container.AccessibleAWTContainer
Returns:
the number of accessible children of this object

getAccessibleDescription

public String getAccessibleDescription()
Returns the localized description of this object.
Overrides:
getAccessibleDescription in interface Component.AccessibleAWTComponent
Returns:
the localized description of this object or null if this object has no description

getAccessibleKeyBinding

public AccessibleKeyBinding getAccessibleKeyBinding()
Returns the keybindings associated with this accessible component or null if the component does not support key bindings.
Specified by:
getAccessibleKeyBinding in interface AccessibleExtendedComponent
Returns:
the keybindings associated with this accessible component

getAccessibleName

public String getAccessibleName()
Returns the localized name for this object. Generally this should almost never return Component.getName() since that is not a localized name. If the object is some kind of text component (like a menu item), then the value of the object may be returned. Also, if the object has a tooltip, the value of the tooltip may also be appropriate.
Overrides:
getAccessibleName in interface Component.AccessibleAWTComponent
Returns:
the localized name for this object or null if this object has no name

getAccessibleRole

public AccessibleRole getAccessibleRole()
Returns the accessible role of this component.
Overrides:
getAccessibleRole in interface Component.AccessibleAWTComponent
Returns:
the accessible role of this component
See Also:
AccessibleRole

getAccessibleStateSet

public AccessibleStateSet getAccessibleStateSet()
Returns the accessible state set of this component.
Overrides:
getAccessibleStateSet in interface Component.AccessibleAWTComponent
Returns:
the accessible state set of this component

getBorderTitle

protected String getBorderTitle(Border border)
Recursivly searches a border hierarchy (starting at border) for a titled border and returns the title if one is found, null otherwise.
Parameters:
border - the border to start search from
Returns:
the border title of a possibly found titled border

getTitledBorderText

public String getTitledBorderText()
Returns the title of the border of this accessible component if this component has a titled border, otherwise returns null.
Specified by:
getTitledBorderText in interface AccessibleExtendedComponent
Returns:
the title of the border of this accessible component if this component has a titled border, otherwise returns null

getToolTipText

public String getToolTipText()
Returns the tooltip text for this accessible component.
Specified by:
getToolTipText in interface AccessibleExtendedComponent
Returns:
the tooltip text for this accessible component

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener listener)
Removes a property change listener from the list of registered listeners. This uninstalls the accessibleContainerHandler and accessibleFocusHandler fields and calls super.removePropertyChangeListener(listener).
Overrides:
removePropertyChangeListener in interface Component.AccessibleAWTComponent
Parameters:
listener - the listener to remove
