Hello

I’m looking for a class named “SyntaxHighlightingEditField”, I think it’s created by Alex Restrepo. And I think [this](http://code.google.com/p/custom-editfield/) class is build on it. But custom editfield is way to big for me. I only want syntax highlighting, and that class worked with simple xml files.

But I can’t find it on Alex Restrepo’s GitHub.

Anyone has this class by chance?

Thanks

Do you have also the problem that it no longer works in XOJO with Cocoa?

I’m not using Xojo, but Realbasic. so I have no answer to that question.

Although, it’s very weird that a thread cannot manipulate an UI element. Maybe someone from Xojo can clear things up?

Yes, with Real Studio 2012 it works.

I have a way found to make it work in XOJO.  
I removed the HighlighterThread and put the Run Code into the Timer.  
It seems to work.

Thanks Alex. That’s very nice.  
The xml files containing the description of the highlight rules follow a generic structure or this is your own development. I mean, is it easy to find other descriptor files (like for Python, etc.) ?
