public class Talk

extends Component

implements ActiveComponent

A simple chat client component. It is a frame with two areas inside: a display area and an input area. Whenever a line is formed in the input area, the line is sent out from the "inout" port. And whenever a message is received from the port, it is displayed in the display area. Ports (in addition to those defined in drcl.comp.Component):

• "inout" port: First, it sends out one line of messages when a line is inputed from the user. The line is prepended with the ID + ": ". Second, the component displays any message comes in from this port.
