[Qt-creator] Issue parsing QStringLiteral() in SpellChecker Plugin

[Typz]

Hello,

At the moment, there are two "levels" of preprocessing: full preprocessor is used for code analysis, while "fast preprocessor" is used for highlighting...

With fast preprocessor, QStringLiteral should not be expanded. So just running fast preprocessor on the source code before parsing strings should solve the problem.

As for matching position, I remember there used to be some functions in c++ editor, which are used for highlighting macros... That was some time ago though, it may have changed since...

Congratulations for making this great plugin, Best Regards,
