real "independent" pointer which is automatically disposed on finalization.This class is used as a generic base class for pointer based objects. See QTHandle for a user-level pointer object. <P> The default setting is for the Ptr to be disposable - you must use the QTPointerRef(int, int, Object) constructor to create a non-disposable reference For non-disposable Pointers there are two situations to look out for:<BR> (1) Upon finalization the pointer should NOT be disposed - it belongs to a parent struct<BR> (2) The parent object from which the pointer is obtained should not be allowed to go away whilst the reference object is alive. <BR> In both situations we must maintain a reference to the parent or owner object.<P><HR><P><!--
