Hi Kåre,

thanks for your response. It was an inspiring suggestion:
OK I was looking for something that the library does for all
consumers. So I looked into QTextDocument but I found nothing that
looked suitable for a forced redraw.
So I remembered: My code does nothing with the document but passing it
to SyntaxHighlighter on creation. That lead me to the (brute force)
solution: Every time a new definition or theme is set, the highlighter
is destroyed and a new one is created [1]. Maybe ugly from performance
point of view but works fine.

Thanks again,
