Hi

I recently released this library http://srchiliteqt.sourceforge.net/

Source-highlight-qt is a library for performing syntax highlighting in 
Qt documents by relying on GNU Source-Highlight library, 
http://www.gnu.org/software/src-highlite/.  and Source-highlight already 
has syntax highlighting for Latex code.

for standard usage, it's just a matter of executing this code (you can 
pass the language syntax, i.e., the source-highlight language definition 
file, to the init method):

QTextEdit *editor = new QTextEdit;
srchiliteqt::Qt4SyntaxHighlighter *highlighter =
  new srchiliteqt::Qt4SyntaxHighlighter(editor->document());
highlighter->init("latex.lang");

please let me know whether you need further help

cheers
	Lorenzo
