Error running executable

There is a good chance your application crashes Try debugging it. What exact OS are you using?

[Salazaar]

I'm using Windows

[wysota]

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

[marcel]

What about actionAbout?
Where is that created?

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

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++.

[Salazaar]

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