derive from CWnd?

Each item in a dialog is derived from CWnd (e.g. a static control, a list
box, a combo box, etc). I am trying to determine whether the same approach
can be used to draw objects in a CView. As a simple example, assume 5
different non-overlapping objects (e.g. 5 circles) are drawn in a CView.
Each object knows how to draw itself and respond to keyboard/mouse input.
The question is, should each object be derived from CWnd? Alternatively,
should each object simply receive a pointer to CView and "USE" this pointer
to draw itself? The latter is the approach I have traditionally taken. Is
there is good reason to use the former approach and have each object be
derived from CWnd? I have no idea how to implement the details (e.g. how to
ensure a selected object receives keyboard/mouse input) so, if this approach
can be implemented, could someone please refer me to any documentation that
describes how it is done?

Thanks in advance

Ian
