Question

After much searching, it looks like I have to assign RegisterComponentsProc and RegisterPropertyEditorProc, which I have done.

However, I thought that I could call my design time Register function, i.e. <myComponentUnit>.Register();.

When I do I get stack overflow, because, well …

procedure myComponentUnit.Regiter;
begin
  RegisterPropertyEditor(TypeInfo(Integer), 
                         TMyComponent, 'myProperty',   TMyProperty);

end;

procedure RegisterPropertyEditor(PropertyType: PTypeInfo;
  ComponentClass: TClass; const PropertyName: string;
  EditorClass: TPropertyEditorClass);
begin
  if Assigned(RegisterPropertyEditorProc) then
    RegisterPropertyEditorProc(PropertyType, ComponentClass, PropertyName,
      EditorClass);
end;

So, I call .Register();
which calls RegisterPropertyEditor()
which call RegisterPropertyEditorProc()
which calls RegisterPropertyEditor() <=== aaargh!!

So, what should I have in the body of my RegisterPropertyEditorProc ?

After further searching, it looks like I want to call DesignEditors.RegisterPropertyEditor() directly, but it is not in the interface section …

There is no point in trying to register a property editor at run-time, as it is not usable at run-time to begin with. It is only usable within the IDE during design-time.
