Strange highlighting in qt-creator

[rock37]

Hey folks,
i get some strange highlightings that makes it hard to read the sourcecode, here an example.

You see the green highlights at MainWindow ? Why is this highlighted and how to get rid of it ?

best regards,

Don't know. But I see it has marked trouble with your #include "mainwindow.h", that could cause mis-parsing, why don't you resolve that first?

@JonB the file mainwindow.h is there, why is he underlining it ??

Why ask me, I don't know, I presume it has some trouble with it? If you hover over the yellow triangle, the yellow line or the yellow light bulb does it tell you something?
