Hi,

I am new to boost.python, so there may be a very simple answer to this. I would like to access the OGRE graphics library from python. But it has several classes with data like this:

union { struct { Real r,g,b,a; }; Real val[4]; };

And I cannot access e.g. 'r' with a statement like:

..def_readwrite("r", &Ogre::ColourValue::r)

I'm assuming this is because there is an unnamed union and unnamed struct in between the class and the 'r'. I could write a new C++ class to wrap this one, and then use boost to wrap *that*. But if there is a simpler way, I would rather use it.

write getter and setter functions and use add_property: Real get_r(Ogre::ColourValue& c) {return c.r;} void set_r(Ogre::ColourValue& c, Real x) { c.r = x;} class_<Ogre::ColourValue>(....) .add_property("r", get_r, set_r) HTH, -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
