Error running executable

Yes, I know that I was asking for a more specific response. And by the way, which compiler do you use?

I don't use a compiler, I compile everything by console (qmake -o Makefile...). Oh, sure, I'm using XP 2000 HE

What about actionAbout?
Where is that created?

It,s created in ui_maker.h

Oh, that will make things easier...

Try running the application without setting that style.
See if it works.

Anyway, I'm going to answer for you: you're using mingw - therefore the compiler is g++.

Yes I'm using MinGW compiler (sorry, wysota)
