 public interface AccessibleComponentTheAccessibleComponentinterface 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 theAccessibleComponentinterface by first obtaining itsAccessibleContextand then calling theAccessibleContext.getAccessibleComponent()method. If the return value is notnull, the object supports this interface.

 - 
isEnabledboolean isEnabled() Determines if the object is enabled. Objects that are enabled will also have theAccessibleState.ENABLEDstate set in theirAccessibleStateSets.- Returns:
- trueif object is enabled; otherwise,- false
- See Also:
- setEnabled(boolean),- AccessibleContext.getAccessibleStateSet(),- AccessibleState.ENABLED,- AccessibleStateSet
 
 - 
setEnabledvoid setEnabled(boolean b) Sets the enabled state of the object.- Parameters:
- b- if- true, enables this object; otherwise, disables it
- See Also:
- isEnabled()
 
 - 
isVisibleboolean isVisible() Determines if the object is visible. Note: this means that the object intends to be visible; however, it may not be showing on the screen because one of the objects that this object is contained by is currently not visible. To determine if an object is showing on the screen, useisShowing()Objects that are visible will also have the AccessibleState.VISIBLEstate set in theirAccessibleStateSets.- Returns:
- trueif object is visible; otherwise,- false
- See Also:
- setVisible(boolean),- AccessibleContext.getAccessibleStateSet(),- AccessibleState.VISIBLE,- AccessibleStateSet

- b- if- true, shows this object; otherwise, hides it
- See Also:
- isVisible()
 
 - 
isShowingboolean isShowing() Determines if the object is showing. This is determined by checking the visibility of the object and its ancestors. Note: this will returntrueeven if the object is obscured by another (for example, it is underneath a menu that was pulled down).- Returns:
- trueif object is showing; otherwise,- false
 
 - 
containsboolean 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.- Parameters:
