Quick thought:
I would reimplement the debug methods of Qt, then use qInstallMsgHandler to
activate them. Would use a QTextEdit with rich-text support. Then in the
message handlers I would print some red colored html for qWarning and black
colored html for qDebug into the QTextEdit. (something like <p><font
color="red">this is an error</font></p>) This is ugly and old-style but a
solution. :) :)
