Is here anybody who used "GammaRay":http://www.kdab.com/kdab-products/gammaray/ . I build GPL version on Windows and Qt 4.8.1 . I am not clearly understand how to use it. I can attach the process but then what? After attaching gammaray just closes.
At first i should been look in forum :)
I found this "http://qt-project.org/forums/viewthread/13052":http://qt-project.org/forums/viewthread/13052 . Thanks to Andre and ZapB.
solution: GammaRay needs to have the exact same build config as the application you are debugging.
