Is the Qt source code complete?

Question

I want to create some custom widgets for my Qt application and thus I need to reimplement some slots.
Now I searched the Qt source code and found ie the cpp file of QSlider ( see here ). I looked for the implementation of setValue(int) , and it is mentioned in the comments a few times, but I couldn't find the implementation.
This led me to the conclusion that either the source code is not complete or that I'm missing something.

方法setValue继承自QAbstractSlider ，你可以在这里看到它的来源。
