This is a composite widget designed to simplify the construction of chat applications. The widget contains display areas for chat messages, user names and topic and an entry area. It automatically handles colourization of messages per nick and manages nick completion. A system of hooks permit the application author to adjust display features. The main chat display area may be split for use displaying history or for searching. The widget is made up of a number of text widget and panedwindow widgets so that the size of each part of the display may be adjusted by the user. All the text widgets may be accessed via widget passthrough commands if fine adjustment is required. The topic and names sections can also be hidden if desired. COMMANDS
