In "screenshot.cpp" of the Screenshot Example for Qt5.7, I saw around 15 comment-like lines of the form //! [int], like //! [0], //! [1], etc. They're syntax-highlighted differently than normal comments (highlighted blue instead of green in Qt Creator). I looked around and thought it might have something to do with the "!" mark in Qdoc, and thought it was unique in Qt, but when I tried typing it into Code::Blocks, it was syntax-highlighted differently too.

Does this syntax have any special meaning in C++? Or is it just a normal comment? I tried googling "c plus plus exclamation comment syntax" but I didn't get anything like this.

Looks like doxygen comment format. – krzaq Nov 09 '16 at 00:29
@krzaq ya, you're right. I didn't even know that existed before. Thanks. – DragonautX Nov 09 '16 at 00:32

@ddriver oh, so it's actually qdoc, and doxygen just allows you to do qdoc syntax then – DragonautX Nov 09 '16 at 00:35
