You sure? When I built Qt last night I used: configure -no-g++-exceptions. I wonder if you change this to yes, do you get your exceptions?

No that has nothing to do with Qt its a only a compiler option. You would need some additional (though trivial) code in Qt. Exceptions are a much better way to do error handling, since you don't have to check for errors based on the return value of each function you call, but can simply monitor a block of code. Another advantage is that exceptions can be thrown during object creation in the constructor and that the return value of a function can be used for something else then an error/status value.

    trivial? The code itself might be trivial, but it's by far not trivial to make a class exception safe. Take a look at the amount of articles about exception-safety on http://www.gotw.ca.

      Ok, agree you have to be a programmer to be able to do it.
