A am using Borland C++ 3.1 for Windows.  I managed to declare an
object of type Bag to store assorted objects in.  Now, I want to call
a certain member function (the paint method) on each object in the
bag.  The only help the manual gives is:

>Bag::forEach
>
>void forEach(void ( *actionFuncPtr)(Oject& o, void *), void *args);
>
>See also: Container::forEach, which states:
>
>virtual void forEach( iterFuncType actionFuncPtr, void *args );
>
>forEach creates an internal iterator to execute the given action
>function for each element in the container.  The args argument lets
>you pass arbitrary data to the action function.

This is all the books say.  Has anyone succerssfully used this
command?  Could someone post a simple example?  Thanks.
