// 
// Micro Windows Implementation 
// object.h: the base class of all other classes 
// 
// $DESC$ 
// This is the revised "root" for the Micro Windows class hierarchy. 
// Object class was renamed to MWObject, while you can still use the 
// originally if _MW_OBJECTCLASS is defined (default is yes.) 
// 
// This revision allows you working with other class hierarchies, 
// such as Borland OWL or Microsoft Foundation class. 
// $ENDDESC$ 
// $CHNDESC$ 
// Object class, 所有其他的 class 皆繼承自此 class. 
// 值得注意的是這裡用到了 virtual destructor .
