What is //! [X] good for??

[QT-static-prgm]

Hello,

i'm currently reading some Qt examples to get my own program working and i often find things like this:
//! [3]
//! [0]

So my Question, what is it good for??

[Q139]

To remind something , maybe copies of repeating code?

No, It's a QDoc annotation for automatic documentation generation. For each example there's a corresponding .qdoc file with text including these annotated pieces of code. See\snippet command docs for details.
