I agree with that.

Just a note.
Ideally, the library won't have to deal with the
numeric control ID's.  You create a widget object and
from now on you use the object's pointer/reference to
access it (no need for an ID).  One exception would be
dialog boxes. Usually resource files are ID-based so
we'll probably need to use the ID's.

boost::gui::dialog<> dlg(IDD_HELLO);
boost::gui::edit* hello_edit(
dlg.get<boost::gui::edit>(IDC_EDIT_HELLO) );

Under the covers the get function would do something
like this:

template< typename T, typename ID = int >
T* dlg::get( ID id )
{
    dlg::const_iterator it;
    for( it = begin(); it < end(); ++it )
    {
        if( it->getid() == id )
            return static_cast<T*>( *it );
    }
    return NULL;
}

It'd be nice to get rid of numeric id's completely.
Any ideas?
