c++ - 如何让 Doxygen 显示菱形继承图

Question

Doxygen 有一个非常巧妙的功能，它可以从代码生成继承图。但是，当从具有公共(public)基类的类使用多重继承时，该图显示了两个独立的基类(即使我使用的是虚拟继承，如基类周围的虚线所示)

我怎样才能让 Doxygen 的情节更像下面这样。 . .

     D
    / \
   B   C
    \ /
     A

而不是:(就像没有虚拟继承时发生的那样)

     D
   /   \
   B   C
   |   |
   A   A

Answer 1

If you set the HAVE_DOT tag to YES then doxygen will assume the dot tool is available from the path. This tool is part of Graphviz (see: http://www.graphviz.org/), a graph visualization toolkit from AT&T and Lucent Bell Labs. The other options in this section have no effect if this option is set to NO The default value is: NO.

设置为

HAVE_DOT = YES
