provides an implementation of the interfaces in the OLE Control protocol, to allow a CAPI pane to be embedded in an OLE Control container implemented outside LispWorks. It is typically used with the macro define-ole-control-component to define a subclass of
that implements a particular coclass from a type library. Instances of this class are usually created by the COM runtime system, not by explicit calls to
A function designator pane-function must be supplied. pane-function that is called when OLE embeds the Control in a container. It receives the component as its argument and should return a CAPI pane that will implement the visual aspects of the control.
