Find out the exact version of the Qt used by the author you app. Get the source code files for the core and other components of that version of the Qt from the QT site, compile them as debug.
Use the associated pdb files from the compiled files and use them in your IDA to generate more meaningful decompilations for your target. You will find your job just made 10-100 times easier

Of course, the above is a 10,000 feet summary view of the process. Anyway, this is the way professionals proceed with complex Qt targets. I used to have an article which gives details of this technique but I cannot find it right now.
