Add error catching?

[it-s]

I have thought about it for some time, and it seems to me that if IM (or Qt) encounters any internal errors app will just crash :(
Can we somehow use try{}catch{} to make sure the errors are at least shown to the user? I have no idea how this works in c++, but it's quite simple in Java.
Maybe you know why this is not a good idea in c++, then tell me please :)
Thanks

That's the problem with C++... You have to test manually ( if a == 0 return 5 /a)
You can also use Q_ASSERT, to show warning on console.
To show warning use :

QMessageBox::information(0, "error", "errorMessage")
