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,

So the thing is that the text document does not get notified that it needs a
redraw... how is
just adding a 'onDefinitionNameChanged: textArea.append("")'
I tried it and it works, but is that too ugly?
Nice wrapper tho... :)

Syntax-Highlighter questions
Hi, a while back I needed syntax-highlighting in a QML based application. Since I could not find some QML support for syntax-highlighter, I wrote a wrapper library [1]. That worked perfectly fine but now that I wrote an example (screenshot in [1]) unexpected behaviour pops up. The example is different because it can set highlighter's definition and theme during runtime which were set once statically in the initial application. Now my issue/question: Highlight definition: Although SyntaxHighlighter::setDefinition calls rehighlight(), the content of the text field remains unchanged. By changing the size of the window, the new highlighting is drawn. Do you have any suggestions what can be done to fix that? Hoping for cure :) and thanks in advance, Andreas [1] https://github.com/schnitzeltony/ksyntax-highlighting-wrapper
