Before the change the compiler raised the warning: 'Gui::ViewProviderDatum::getRoot' hides overloaded virtual function [-Werror,-Woverloaded-virtual] In the base class the method getRoot() is declared as const while in ViewProviderDatum it's not and that's why it's considered as an overloaded method. However, this signature causes two problems: 1. In the client code it's not always clear which version of getRoot() should be called 2. It violates const-correctness So, trying to declare the method ViewProviderDatum::getRoot() as const it now overrides the method of the base class (and fixes the warning) but this doesn't lead to the expected result: See https://forum.freecad.org/viewtopic.php?p=796064#p796064 The other option is to rename the method. And this gives the expected result now.
