Adds the specified focus listener to receive focus events from this component.
Specified by:
addFocusListener in interface AccessibleComponent
Parameters:
l - the focus listener

contains

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.
Specified by:
contains in interface AccessibleComponent

Parameters:
p - The point relative to the coordinate system of this object.
Returns:
the Accessible, if it exists, at the specified location; otherwise null

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.

getAccessibleContext

public AccessibleContext getAccessibleContext()
Returns the AccessibleContext associated with this object. In most cases, the return value should not be null if the object implements interface Accessible. If a component developer creates a subclass of an object that implements Accessible, and that subclass is not Accessible, the developer should override the getAccessibleContext method to return null.
Specified by:
getAccessibleContext in interface Accessible

getAccessibleIndexInParent

public int getAccessibleIndexInParent()
Gets the 0-based index of this object in its accessible parent.
Overrides:
getAccessibleIndexInParent in interface AccessibleContext

Specified by:
getBackground in interface AccessibleComponent
Returns:
the background color, if supported, of the object; otherwise, null

getBounds

Returns:
A rectangle indicating this component's bounds; null if this object is not on the screen.

getCursor

public Cursor getCursor()
Gets the Cursor of this object.

            throws IllegalComponentStateException
Gets the locale of the component. If the component does not have a locale, then the locale of its parent is returned.
Overrides:
getLocale in interface 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.
