But that is also outside the scope of this forum, which is for helping with Qt programming.
I suggest you look at forums dealing with ENC/DNC issues.
Since the answer was a general one, and not that specifically all ENC/DNC libraries are compatible with Qt, is isn't strictly true that every C/C++ library is compatible with Qt. In the case of graphics (which applies to rendering electronic charts), a binding to Qt is required. If one doesn't exist, it can be created if the C/C++ library is open source; otherwise it may not be possible to create the binding, in which case the library in question would not compatible. For example, Open Inventor/Coin3D have the SoQt class to bind an SoRenderArea to a QWidget or subclass. Without that, maybe OIV could render in its own window, but it wouldn't be integrated into the Qt application.

I'll check the electronic charting forums...
