Enclosing class:

JComponent

public abstract class JComponent.AccessibleJComponent
extends Container.AccessibleAWTContainer
implements AccessibleExtendedComponent

Inner class of JComponent used to provide default support for accessibility. This class is not meant to be used directly by application developers, but is instead meant only to be subclassed by component developers.

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. Please see XMLEncoder.

Since:

1.2

Field Details

accessibleFocusHandler

@Deprecated
protected FocusListener accessibleFocusHandler

Deprecated.

This field duplicates the function of the accessibleAWTFocusHandler field in java.awt.Component.AccessibleAWTComponent, so it has been deprecated.

Constructor Details

AccessibleJComponent

protected AccessibleJComponent()

Though the class is abstract, this should be called by all sub-classes.

Method Details

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)

Adds a PropertyChangeListener to the listener list.

Overrides:

addPropertyChangeListener in class Container.AccessibleAWTContainer

Parameters:

listener - the PropertyChangeListener to be added

See Also:

• AccessibleContext.ACCESSIBLE_NAME_PROPERTY
• AccessibleContext.ACCESSIBLE_DESCRIPTION_PROPERTY
• AccessibleContext.ACCESSIBLE_STATE_PROPERTY
• AccessibleContext.ACCESSIBLE_VALUE_PROPERTY
• AccessibleContext.ACCESSIBLE_SELECTION_PROPERTY
• AccessibleContext.ACCESSIBLE_TEXT_PROPERTY
• AccessibleContext.ACCESSIBLE_VISIBLE_DATA_PROPERTY

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener listener)

Removes a PropertyChangeListener from the listener list. This removes a PropertyChangeListener that was registered for all properties.

Overrides:

removePropertyChangeListener in class Container.AccessibleAWTContainer

Parameters:

listener - the PropertyChangeListener to be removed

getBorderTitle

protected String getBorderTitle(Border b)

Recursively search through the border hierarchy (if it exists) for a TitledBorder with a non-null title. This does a depth first search on first the inside borders then the outside borders. The assumption is that titles make really pretty inside borders but not very pretty outside borders in compound border situations. It's rather arbitrary, but hopefully decent UI programmers will not create multiple titled borders for the same component.

Parameters:

b - the Border for which to retrieve its title

Returns:

the border's title as a String, null if it has no title

getAccessibleName

public String getAccessibleName()

Gets the accessible name of this object. This should almost never return java.awt.Component.getName(), as that generally isn't a localized name, and doesn't have meaning for the user. If the object is fundamentally a text object (such as a menu item), the accessible name should be the text of the object (for example, "save"). If the object has a tooltip, the tooltip text may also be an appropriate String to return.

Overrides:

getAccessibleName in class Component.AccessibleAWTComponent

Returns:

the localized name of the object -- can be null if this object does not have a name

See Also:

• AccessibleContext.setAccessibleName(java.lang.String)

getAccessibleDescription

public String getAccessibleDescription()

Gets the accessible description of this object. This should be a concise, localized description of what this object is - what is its meaning to the user. If the object has a tooltip, the tooltip text may be an appropriate string to return, assuming it contains a concise description of the object (instead of just the name of the object - for example a "Save" icon on a toolbar that had "save" as the tooltip text shouldn't return the tooltip text as the description, but something like "Saves the current text document" instead).

Overrides:

getAccessibleDescription in class Component.AccessibleAWTComponent

Returns:

the localized description of the object -- can be 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.

Overrides:

getAccessibleRole in class Component.AccessibleAWTComponent

Returns:

an instance of AccessibleRole describing the role of the object

See Also:

• AccessibleRole

getAccessibleStateSet

public AccessibleStateSet getAccessibleStateSet()

Gets the state of this object.

Overrides:

getAccessibleStateSet in class Component.AccessibleAWTComponent

Returns:

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

See Also:

• AccessibleState

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 class Container.AccessibleAWTContainer

Returns:

the number of accessible children in the object.

getAccessibleChild

public Accessible getAccessibleChild(int i)

Returns the nth Accessible child of the object.

Overrides:

getAccessibleChild in class Container.AccessibleAWTContainer

Parameters:

i - zero-based index of child

Returns:

the nth Accessible child of the object

See Also:

• AccessibleContext.getAccessibleChildrenCount()

getToolTipText

public String getToolTipText()

Returns the tool tip text

Specified by:

getToolTipText in interface AccessibleExtendedComponent

Returns:

the tool tip text, if supported, of the object; otherwise, null

Since:

1.4

getTitledBorderText

public String getTitledBorderText()

Returns the titled border text

Specified by:

getTitledBorderText in interface AccessibleExtendedComponent

Returns:

the titled border text, if supported, of the object; otherwise, null

Since:

1.4

getAccessibleKeyBinding

public AccessibleKeyBinding getAccessibleKeyBinding()

Returns key bindings associated with this object

Specified by:

getAccessibleKeyBinding in interface AccessibleExtendedComponent

Returns:

the key bindings, if supported, of the object; otherwise, null

Since:

1.4

• AccessibleKeyBinding
