The visual links between functions are recovered. The demo is synchronized with a corresponding demo from Qt (qt486-vc10-32\examples\graphicsview\elasticnodes). It may be successfully compiled by any further versions of Qt including 5.10.1 Also, because Open CASCADE (and OCAF in particular) is improved for usage in multi-threading mode, usage of mutexes is added in this sample (for access to the sharing TNaming_UsedShapes attribute, for example).
