The
QTextBrowserinheritsQTextEdit, which works on aQTextDocument. The QTextDocument can be converted to (and saved as) HTML usingQTextDocument::toHtml():I advise you to append to a log file every time a new message comes in / goes out, so update the QTextBrowser and the file "in parallel", and not saving the entire chat history everytime a new message appears.
To do so, open the log file and manually write the open
<html>and<body>tags without closing them. Then append the chat log entries on the still opened file. On application exit (object destruction of the chat window or whatever), close the</body>and</html>tags and afterwards the file itself. This will result in a much better performance than saving the whole file for every change of the QTextBrowser widget.
