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 JavaBeansTM has been added to the
java.beanspackage. Please seeXMLEncoder.

public void addPropertyChangeListener(PropertyChangeListener listener)
Adds a PropertyChangeListener to the listener list.- Overrides:
addPropertyChangeListenerin classContainer.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
-
public void removePropertyChangeListener(PropertyChangeListener listener)
Removes a PropertyChangeListener from the listener list. This removes a PropertyChangeListener that was registered for all properties.- Overrides:
removePropertyChangeListenerin classComponent.AccessibleAWTComponent- Parameters:
listener- the PropertyChangeListener to be removed
-
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.
-
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:
getAccessibleNamein classComponent.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)
-
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:
getAccessibleDescriptionin classComponent.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)
-
public AccessibleRole getAccessibleRole()
Gets the role of this object.- Overrides:
getAccessibleRolein classComponent.AccessibleAWTComponent- Returns:
- an instance of AccessibleRole describing the role of the object
- See Also:
AccessibleRole
-
public AccessibleStateSet getAccessibleStateSet()
Gets the state of this object.- Overrides:
getAccessibleStateSetin classComponent.AccessibleAWTComponent- Returns:
- an instance of AccessibleStateSet containing the current state set of the object
- See Also:
AccessibleState
-
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 classContainer.AccessibleAWTContainer- Returns:
- the number of accessible children in the object.
-
public Accessible getAccessibleChild(int i)
Returns the nth Accessible child of the object.- Overrides:
getAccessibleChildin classContainer.AccessibleAWTContainer- Parameters:
i- zero-based index of child- Returns:
- the nth Accessible child of the object
- See Also:
AccessibleContext.getAccessibleChildrenCount()
-
public String getToolTipText()
Returns the tool tip text- Specified by:
getToolTipTextin interfaceAccessibleExtendedComponent- Returns:
- the tool tip text, if supported, of the object; otherwise, null
- Since:
- 1.4
-
public String getTitledBorderText()
Returns the titled border text- Specified by:
getTitledBorderTextin interfaceAccessibleExtendedComponent- Returns:
- the titled border text, if supported, of the object; otherwise, null
- Since:
- 1.4
-
public AccessibleKeyBinding getAccessibleKeyBinding()
Returns key bindings associated with this object- Specified by:
getAccessibleKeyBindingin interfaceAccessibleExtendedComponent- Returns:
- the key bindings, if supported, of the object; otherwise, null
- Since:
- 1.4
- See Also:
AccessibleKeyBinding
