  27 // window if it has a parent and is positioned within the parent. For example,
  28 // wxFrame is non-owned, because even though it can have a parent, it's
  29 // location is independent of it.  This class is for internal use only, it's
  30 // the base class for wxTopLevelWindow and wxPopupWindow.
