cocos2d-x3.x windows环境下 textfield无法处理TEXTFIELD_EVENT_DELETE_BACKWARD事件

1、修改cocos2d-x-3.x\cocos\2d\platform\desktop\CCGLView.cpp   onGLFWKeyCallback函数

 1 static void onGLFWKeyCallback(GLFWwindow* window, int key, int scancode, int action, int mods)
 2     {
 3         if (_view)
 4             _view->onGLFWKeyCallback(window, key, scancode, action, mods);
 5
 6         if (GLFW_REPEAT != action)
 7         {
 8             EventKeyboard event(g_keyCodeMap[key], GLFW_PRESS == action);
 9             if ((EventKeyboard::KeyCode::KEY_BACKSPACE == event._keyCode) && event._isPressed)
10             {
11                 IMEDispatcher::sharedDispatcher()->dispatchDeleteBackward();
12             }
13             else
14             {
15                 auto dispatcher = Director::getInstance()->getEventDispatcher();  dispatcher->dispatchEvent(&event);
16             }
17         }
18     }

2、在CCGLView.cpp中 把声明g_keyCodeMap放到最前面， 如下这句：

1 static std::unordered_map<int, EventKeyboard::KeyCode> g_keyCodeMap;

3、修改cocos2d-x-3.x\cocos\2d\CCEventKeyboard.h

1 public:
2     KeyCode _keyCode;
3     bool _isPressed;
4
5 private:
6     friend class EventListenerKeyboard;
