How to speed up signal/slot debugging or ignore only some files?

Question

Qt

There is Qt, mingw, QtCreator.
It is often necessary to look at which slot(s) will trigger a signal and jump into it.

Now you have to manually search for all connections of the signal of interest, set stops at the input.
I would like, ideally, to just put it on emit and immediately get into the slots when called (now there is an exciting journey through the innards of Qt first).

If this is not possible at the moment, is it possible to somehow set automatic exit from functions if we get into them, if the sources are in the specified directory?
Or how to deal with such situations?
