Class JList.AccessibleJList.AccessibleJListChild

Method Details

• getAccessibleContext

  public AccessibleContext getAccessibleContext()

  Get the AccessibleContext for this object. In the implementation of the Java Accessibility API for this class, returns this object, which is its own AccessibleContext.

  Specified by:

  getAccessibleContext in interface Accessible

  Returns:

  this object

• setAccessibleName

  public void setAccessibleName(String s)

  Description copied from class: AccessibleContext

  Sets the localized accessible name of this object. Changing the name will cause a PropertyChangeEvent to be fired for the ACCESSIBLE_NAME_PROPERTY property.

  Overrides:

  setAccessibleName in class AccessibleContext

  Parameters:

  s - the new localized name of the object

  See Also:

  • AccessibleContext.getAccessibleName()
  • AccessibleContext.addPropertyChangeListener(java.beans.PropertyChangeListener)

• setAccessibleDescription

  public void setAccessibleDescription(String s)

  Description copied from class: AccessibleContext

  Sets the accessible description of this object. Changing the name will cause a PropertyChangeEvent to be fired for the ACCESSIBLE_DESCRIPTION_PROPERTY property.

  Overrides:

  setAccessibleDescription in class AccessibleContext

  Parameters:

  s - the new localized description of the object

  See Also:

  • AccessibleContext.setAccessibleName(java.lang.String)
  • AccessibleContext.addPropertyChangeListener(java.beans.PropertyChangeListener)

• getAccessibleRole

  public AccessibleRole getAccessibleRole()

  Description copied from class: AccessibleContext

  Gets the role of this object. The role of the object is the generic purpose or use of the class of this object. For example, the role of a push button is AccessibleRole.PUSH_BUTTON. The roles in AccessibleRole are provided so component developers can pick from a set of predefined roles. This enables assistive technologies to provide a consistent interface to various tweaked subclasses of components (e.g., use AccessibleRole.PUSH_BUTTON for all components that act like a push button) as well as distinguish between subclasses that behave differently (e.g., AccessibleRole.CHECK_BOX for check boxes and AccessibleRole.RADIO_BUTTON for radio buttons).

  Note that the AccessibleRole class is also extensible, so custom component developers can define their own AccessibleRole's if the set of predefined roles is inadequate.

  Specified by:

  getAccessibleRole in class AccessibleContext

  Returns:

  an instance of AccessibleRole describing the role of the object

  See Also:

  • AccessibleRole

• getAccessibleStateSet

  public AccessibleStateSet getAccessibleStateSet()

  Description copied from class: AccessibleContext

  Gets the state set of this object. The AccessibleStateSet of an object is composed of a set of unique AccessibleStates. A change in the AccessibleStateSet of an object will cause a PropertyChangeEvent to be fired for the ACCESSIBLE_STATE_PROPERTY property.

  Specified by:

  getAccessibleStateSet in class AccessibleContext

  Returns:

  an instance of AccessibleStateSet containing the current state set of the object

  See Also:

  • AccessibleStateSet
  • AccessibleState
  • AccessibleContext.addPropertyChangeListener(java.beans.PropertyChangeListener)

• getAccessibleIndexInParent

  public int getAccessibleIndexInParent()

  Description copied from class: AccessibleContext

  Gets the 0-based index of this object in its accessible parent.

• getAccessibleChild

  public Accessible getAccessibleChild(int i)

  Description copied from class: AccessibleContext

  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.

  Specified by:

  getAccessibleChild in class AccessibleContext

  Parameters:

  i - zero-based index of child

  Returns:

  the Accessible child of the object
