Yes.  But:
    sph_cmplx->value = 0.25;
...works in C++ too, since SoSFFloat does (this is from the output of
CC -E /usr/include/Inventor/fields/SoSFFloat.h):

    ... bunch of stuff ...
    float operator= (float newValue){ setValue(newValue); return value;}
    ... etc ..

Operator overloading can be very convenient, but it is actually one of
my least favorite features of C++...
