public interface AccessibleComponent

The AccessibleComponent interface should be supported by any object that is rendered on the screen. This interface provides the standard mechanism for an assistive technology to determine and set the graphical representation of an object. Applications can determine if an object supports the AccessibleComponent interface by first obtaining its AccessibleContext and then calling the AccessibleContext.getAccessibleComponent() method. If the return value is not null, the object supports this interface.

Method Summary

void	addFocusListener (FocusListener l) Adds the specified focus listener to receive focus events from this component.
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.
Accessible	getAccessibleAt (Point p) Returns the Accessible child, if one exists, contained at the local coordinate Point.
Color	getBackground () Gets the background color of this object.
Rectangle	getBounds () Gets the bounds of this object in the form of a Rectangle object.
Cursor	getCursor () Gets the Cursor of this object.
Font	getFont () Gets the Font of this object.
FontMetrics	getFontMetrics (Font f) Gets the FontMetrics of this object.
Color	getForeground () Gets the foreground color of this object.
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.
Point	getLocationOnScreen () Returns the location of the object on the screen.
Dimension	getSize () Returns the size of this object in the form of a Dimension object.
boolean	isEnabled () Determines if the object is enabled.
boolean	isFocusTraversable () Returns whether this object can accept focus or not.
boolean	isShowing () Determines if the object is showing.
boolean	isVisible () Determines if the object is visible.
void	removeFocusListener (FocusListener l) Removes the specified focus listener so it no longer receives focus events from this component.
void	requestFocus () Requests focus for this object.
void	setBackground (Color c) Sets the background color of this object.
void	setBounds (Rectangle r) Sets the bounds of this object in the form of a Rectangle object.
void	setCursor (Cursor cursor) Sets the Cursor of this object.
void	setEnabled (boolean b) Sets the enabled state of the object.
void	setFont (Font f) Sets the Font of this object.
void	setForeground (Color c) Sets the foreground color of this object.
void	setLocation (Point p) Sets the location of the object relative to the parent.
void	setSize (Dimension d) Resizes this object so that it has width and height.
void	setVisible (boolean b) Sets the visible state of the object.
