Inner class of Component 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.

The class used to obtain the accessible role for this object.

Method from java.awt.Component$AccessibleAWTComponent Detail:
 public  void addFocusListener(FocusListener l) 
    Adds the specified focus listener to receive focus events from this component.
 public  void addPropertyChangeListener(PropertyChangeListener listener) 
    Adds a PropertyChangeListener to the listener list.
 public boolean contains(Point p) 
    Checks whether the specified point is within this object's bounds, where the point's x and y coordinates are defined to be relative to the coordinate system of the object.
 public Accessible getAccessibleAt(Point p) 
    Returns the Accessible child, if one exists, contained at the local coordinate Point. Otherwise returns null.
 public Accessible getAccessibleChild(int i) 
    Returns the nth Accessible child of the object.
 public int getAccessibleChildrenCount() 
    Returns the number of accessible children in the object. If all of the children of this object implement Accessible, then this method should return the number of children of this object.
 public AccessibleComponent getAccessibleComponent() 
    Gets the AccessibleComponent associated with this object if one exists. Otherwise return null.
 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 - e.g. 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).
 public int getAccessibleIndexInParent() 
    Gets the index of this object in its accessible parent.
 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 (e.g. a menu item), the accessible name should be the text of the object (e.g. "save"). If the object has a tooltip, the tooltip text may also be an appropriate String to return.
 public Accessible getAccessibleParent() 
    Gets the Accessible parent of this object. If the parent of this object implements Accessible, this method should simply return getParent.
 public AccessibleRole getAccessibleRole() 
    Gets the role of this object.
 public AccessibleStateSet getAccessibleStateSet() 
    Gets the state of this object.
 public Color getBackground() 
    Gets the background color of this object.
 public Rectangle getBounds() 
    Gets the bounds of this object in the form of a Rectangle object. The bounds specify this object's width, height, and location relative to its parent.
 public Cursor getCursor() 
    Gets the Cursor of this object.
 public Font getFont() 
    Gets the Font of this object.
 public FontMetrics getFontMetrics(Font f) 
    Gets the FontMetrics of this object.
 public Color getForeground() 
    Gets the foreground color of this object.
 public Locale getLocale() 
    Returns the locale of this object.
 public Point getLocation() 
    Gets the location of the object relative to the parent in the form of a point specifying the object's top-left corner in the screen's coordinate space.
 public Point getLocationOnScreen() 
    Returns the location of the object on the screen.
 public Dimension getSize() 
    Returns the size of this object in the form of a Dimension object. The height field of the Dimension object contains this objects's height, and the width field of the Dimension object contains this object's width.
 public boolean isEnabled() 
    Determines if the object is enabled.
 public boolean isFocusTraversable() 
    Returns whether this object can accept focus or not.
 public boolean isShowing() 
    Determines if the object is showing. This is determined by checking the visibility of the object and ancestors of the object. Note: this will return true even if the object is obscured by another (for example, it happens to be underneath a menu that was pulled down).
 public boolean isVisible() 
    Determines if the object is visible. Note: this means that the object intends to be visible; however, it may not in fact be showing on the screen because one of the objects that this object is contained by is not visible. To determine if an object is showing on the screen, use isShowing.
 public  void removeFocusListener(FocusListener l) 
    Removes the specified focus listener so it no longer receives focus events from this component.
 public  void removePropertyChangeListener(PropertyChangeListener listener) 
    Remove a PropertyChangeListener from the listener list. This removes a PropertyChangeListener that was registered for all properties.
 public  void requestFocus() 
    Requests focus for this object.
 public  void setBackground(Color c) 
    Sets the background color of this object. (For transparency, see isOpaque.)
 public  void setBounds(Rectangle r) 
    Sets the bounds of this object in the form of a Rectangle object. The bounds specify this object's width, height, and location relative to its parent.
 public  void setCursor(Cursor cursor) 
    Sets the Cursor of this object.

    The method may have no visual effect if the Java platform implementation and/or the native system do not support changing the mouse cursor shape.

 public  void setEnabled(boolean b) 
    Sets the enabled state of the object.
 public  void setFont(Font f) 
    Sets the Font of this object.
 public  void setForeground(Color c) 
    Sets the foreground color of this object.
 public  void setLocation(Point p) 
    Sets the location of the object relative to the parent.
 public  void setSize(Dimension d) 
    Resizes this object so that it has width and height.
 public  void setVisible(boolean b) 
    Sets the visible state of the object.
