/**
 * <p>
 * The class propertyDialog is used to set the bean
 * properties. A user can add an actionListener to be notified when the
 * "Apply" or "OK" button is pressed.
 * </p>
 *
 * <p>
 * The user can configure the host name, the port number, the community
 * name, the socket type and the update interval. 
 * </p>
 *
 * <p>
 * The "Try it" button activates the IsHostReachableBean, who will probe
 * the configured host and signals the UI since when the host was up.
