error: incomplete type 'blink::Event' named in nested name specifier note: forward declaration of 'blink::Event'

c++编译报错：

.\../../third_party/blink/renderer/modules/clipboard/clipboard.cc(34,19): error: incomplete type 'blink::Event' named in nested name specifier
   DispatchEvent(*Event::Create(event_type_names::kChange));
                  ^~~~~~~
../..\third_party/blink/renderer/core/dom/events/registered_event_listener.h(34,7): note: forward declaration of 'blink::Event'
class Event;
      ^
1 error generated.

 

这是由于在所继承的父类中申明了 class Event；但是没有引用的event.h头文件。

只要在cc文件中加入头文件，就解决。
