VS搭建lua开发环境和LuaBridge注册c++类(cocos2dx项目)（三） 给editbox添加事件

直接贴出实现代码

 1 void ScriptManager::addEditBoxEvent(LuaEditBox* ui, std::string funName)

 2 {

 3     std::string editBoxEditingDidBegin = funName + "_editBoxEditingDidBegin";

 4     std::string editBoxEditingDidEnd = funName + "_editBoxEditingDidEnd";

 5     std::string editBoxTextChanged = funName + "_editBoxTextChanged";

 6     std::string editBoxReturn = funName + "_editBoxReturn";

 7 

 8     auto dbg = new LuaRef(getGlobal(luaState, editBoxEditingDidBegin.c_str()));

 9     auto ded = new LuaRef(getGlobal(luaState, editBoxEditingDidEnd.c_str()));

10     auto tc = new LuaRef(getGlobal(luaState, editBoxTextChanged.c_str()));

11     auto br = new LuaRef(getGlobal(luaState, editBoxReturn.c_str()));

12 

13     try

14     {

15         if (dbg->isFunction())

16         {

17             ui->dbg = [dbg](){(*dbg)(); };

18         }

19         if (ded->isFunction())

20         {

21             ui->ded = [ded](){(*ded)(); };

22         }

23         if (tc->isFunction())

24         {

25             ui->tc = [tc](){(*tc)(); };

26         }

27         if (br->isFunction())

28         {

29             ui->br = [br](){(*br)(); };

30         }

31     }

32     catch (LuaException& e)

33     {

34         CCLog("lua error: %s", e.what());

35     }

36 

37 }

下面是editbox封装类

 1 class LuaEditBox :public Layer, public EditBoxDelegate, public IMEDelegate

 2 {

 3 public:

 4     LuaEditBox();

 5     ~LuaEditBox();

 6 

 7     static LuaEditBox* create(Node* node, int flag, Vec2 pos);

 8 

 9     std::string getName();

10 

11     std::string getText();

12 

13     static int boxNumber;

14 //    LuaEditBox* createEditBox(Node* node,int flag, Vec2 pos = Vec2(0,0) );

15 

16     void editBoxEditingDidBegin(EditBox* editBox)

17     {

18         if (dbg){ dbg(); };

19     };

20     void editBoxEditingDidEnd(EditBox* editBox)

21     {

22         if (ded){ ded(); }; 

23     };

24     void editBoxTextChanged(EditBox* editBox, const std::string& text)

25     { 

26         if (tc)

27         {

28             tc();

29         }; 

30     };

31     void editBoxReturn(EditBox* editBox)

32     {

33         if (br){ br(); };

34     };

35     virtual void keyboardWillShow(IMEKeyboardNotificationInfo& info){};

36 

37     /*void (*dbg)();

38     void (*ded)();

39     void (*tc)();

40     void (*br)();*/

41 

42     std::function<void()> dbg;

43     std::function<void()> ded;

44     std::function<void()> tc;

45     std::function<void()> br;

46 

47 protected:

48     EditBox* m_editBox;

49 private:

50 

51     std::string _name;

52 

53 };
