35 This is a composite widget designed to simplify the construction of
36 chat applications. The widget contains display areas for chat messages,
37 user names and topic and an entry area. It automatically handles
38 colourization of messages per nick and manages nick completion. A sys‐
39 tem of hooks permit the application author to adjust display features.
40 The main chat display area may be split for use displaying history or
41 for searching.

45 the user. All the text widgets may be accessed via widget passthrough
46 commands if fine adjustment is required. The topic and names sections
