object.h

做为linux下图形用户界面支持系统之一的MicroWindows采用C++设计

//
// 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 .
