ENC and/or DNC C++ libraries or kernels

[wysota]

At least one, SevenCs ECDIS Kernel, is compatible with Qt.

Every C++ library is compatible with Qt (unless there are some symbol conflicts which is nowadays almost impossible). It might not cooperate with it in any special way but it is compatible. Especially considering the fact that Qt has many other applications than graphics and ui.

The SevenCs product is intended to render into a bitmap, so the considerations that were discussed relative in particular to Open Inventor/Coin3D earlier in this thread don't apply, and I fully agree that there are no compatibility issues.

To summarize, earlier in the thread the discussion (d)evolved (?) into how Open Inventor/Coin3D work. I could be wrong, but it seems like the people who participated in the discussion have never used OIV, although they didn't explicitly say that.

As far as I'm concerned (and I'm not telling anyone else what to think or do), if a GUI toolkit forces you to write code to have OIV render into a bitmap a lot of the power of OIV (as well as a lot of the co$t of OIV) is being wasted. In that case, I wouldn't consider the GUI toolkit and OIV to be fully compatible. This is, however a non-issue, since most toolkits one would likely encounter (Qt, FLTK, Win32...) have OIV bindings. (And I would suggest that the existence of these bindings attests to their utility.)

I think it's time to close off this thread! I appreciate the many responses I've received telling me how OIV works, but will continue to use Open Inventor with SoQt even if that's a really bad thing to do...

Thanks God Qt is not one of those toolkits... Are you talking about any toolkit in particular?

As far as I know, Open Inventor/Coin3D are fully supported (i.e. bindings are available) for Qt, Windows, X11, WxWidgets, FLTK and probably others I'm not aware of. I was thinking in the other direction: If one has a powerful tool (OIV) and a powerful GUI toolkit like Qt, why not use their capabilities to the maximum?

But what prevents you from doing that?

Absolutely nothing prevents that. That's been my point all along.
