Try catch doesn’t work...

Hi fox
I've been used try/catch in my application, but it can't handle any error, my compiler is MinGW and Qt version is 4.8.2, I've been reconfigure qt with -exceptions, but not work...
also, i want to handle SEH error,
please help me to fix this problem

This is not a issue of Qt, try/catch designed to deal with C++ exceptions. You should not use them in other cases, such as SEH.

Tucnak: That is not correct. Qt does support exceptions, it just does not use them itself in most of its modules. There actually are some that require exceptions though.

Sorry to interrupt, can someone enlighten me as to what is meant by "SEH error"? I think I've never seen that one before.

Sorry, but I have never seen exceptions in Qt code. And there are no any examples with them.

Hi sierdzio,
SEH means Structured Exception Handling, which is Windows only.

Ah, many thanks! That's probably why it was unknown to me.
Cheers, and carry on with your topic :)

I think, your original problem is not with MinGW and is not with Qt.
Exceptions are "only" ANSI/ISO C++ problem.
Probably you misunderstand with the exceptions itself.
There is a very good (imho: the best) and FREE book about C++ and of course about exceptions:
