Does it make sense to use Qt for increasing the productivity in an MFC

Does it make sense to use Qt for increasing the productivity in an MFC app, without actually using the Qt user interface system?

I am currently looking or a good productivity library for my MFC based application, with useful container classes, string algorithmus, threading classes, I/O classes and so on. The Qt API is very nice in my opinion. However, since I don’t want to switch my UI to Qt (just too much effort), I am wondering whether Qt can be used well in a MFC app without any Qt UI.

Thanks in advance for your opinions.

    Qt is divided into several modules (QtGui being one of them). You can hand pick which modules are used by your application by linking only against the libraries you need.

    I cannot answer whether Qt will be interopable with MFC. But at the very least, QString offers conversion to std::string and char*/wchar, which should help you quite a bit.

    The Qt documentation provides an overview over the modules.

    As daniel pointed out below, you have to be aware of the event loop. It is possible however to use the event loop without the GUI module. You can call processEvents on QCoreApplication to process all queued events and then return. There is one caveat with deferred deletions, but the documentation describes the workaround.
