When compiling as debug version in Visual Studio you can step into all Qt functions.
Hmm... why should I have to compile Qt? I have downloaded and installed the Qt SDK and asked for the MSVC version of Qt to be installed. Also, and for good measure, I thought, I installed Qt's source code. So, from there, I would expect to be able to trace into Qt's source code using CDB from within Qt Creator, but I am clearly wrong since I can't seem to be able to do that...
