You don't need someone smarter - you just need to read the error message and think about what it is telling you.

I am not a C++ programmer, but it looks like you are trying to see if the contents of variable 'source' matches a pattern in a Regular Expression. However, this has no meaning because the system cannot possibly guess what pattern you want it to match against as you have not told it what pattern you want. My guess is that QRegExp is a class for regular expressions; so you will have to instantiate it, telling it (either in the constructor call or in a method of the instantiated object) what the Regular Expression that you wish to use is.

The error message that you have got is the compiler telling you that you are trying to run a member function (i.e. a method of a class) without having created an object and the function needs an object to use (which presumably has been told what Regular Expression pattern you are wanting to use for the comparison).
