Member Function Documentation

   void SoContextHandler::destructingContext (uint32_t contextid) [static]
       This method must be called by client code which destructs a context, to
       guarantee that there are no memory leaks upon context destruction.
       This will take care of correctly freeing context-bound resources, like
       OpenGL texture objects and display lists.

       Before calling this function, the context must be made current.

       Note that if you are using one of the standard GUI-binding libraries
       from Kongsberg Oil & Gas Technologies, this is taken care of
       automatically for contexts for canvases set up by SoQt, SoWin, etc.

   void SoContextHandler::addContextDestructionCallback (ContextDestructionCB
       * func, void * closure) [static] Add a callback which will be called
       every time a GL context is destructed. The callback should delete all
       GL resources tied to that context.
       All nodes/classes that allocate GL resources should set up a callback
       like this. Add the callback in the constructor of the node/class, and
       remove it in the destructor.

   void SoContextHandler::removeContextDestructionCallback
       (ContextDestructionCB * func, void * closure) [static] Remove a context
       destruction callback.
