Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Overrides:

toString in class Object

Returns:

a string representation of the object.

itemStateChanged

public void itemStateChanged(ItemEvent e)

Callback method as ItemListener. Updates internal state based on the given ItemEvent.

Here: synchs selected property if isStateAction(), does nothing otherwise.

Specified by:

itemStateChanged in interface ItemListener

e - the ItemEvent fired by a ItemSelectable on changing the selected state.
