Class HintManager

java.lang.Object
  com.isti.util.gui.HintManager

All Implemented Interfaces:

java.util.EventListener, java.awt.event.FocusListener, java.awt.event.MouseListener

public class HintManager

extends java.lang.Object

implements java.awt.event.FocusListener, java.awt.event.MouseListener

HintManager is a reusable class that provides an implementation for status-bar hints. Using it is straightforward. Just construct an instance of HintManager passing a hint component (JLabel or JTextField) instance that will be used to display the hints; call the method addHintFor to set a hint for each component you want; and call the method enableHints for the user interface top container (window, frame, dialog box, etc.) after adding all the components.
