您可能需要GraphViz生成图形.有a simple example和output.

这是由doxgen生成的图例文件中的一个更复杂的例子：

代码(注意：如果只想生成图形,则不需要注释.)：

/*! Invisible class because of truncation */
class Invisible { };

/*! Truncated class,inheritance relation is hidden */
class Truncated : public Invisible { };

/* Class not documented with doxygen comments */
class Undocumented { };

/*! Class that is inherited using public inheritance */
class PublicBase : public Truncated { };

/*! A template class */
template<class T> class Templ { };

/*! Class that is inherited using protected inheritance */
class ProtectedBase { };

/*! Class that is inherited using private inheritance */
class PrivateBase { };

/*! Class that is used by the Inherited class */
class Used { };

/*! Super class that inherits a number of other classes */
class Inherited : public PublicBase,protected ProtectedBase,private PrivateBase,public Undocumented,public Templ<int>
{
  private:
    Used *m_usedClass;
};

结果：

您不需要对代码进行评论来生成这些图形.第一个例子根本没有任何意见.第二个例子有一个没有Doxygen风格评论的类.只需设置相应的参数(至少应该设置EXTRACT_ALL = YES),我不记得是否需要这样做).
