COCOS2DX 3.2 Fix input box (TEXTFIELD,TEXTFIELDTTF) The input method in Windows is garbled in Chinese

No system learning is a lot of problems, encountered many problems, such as all the OpenGL API must be called in the main thread,

This let me in the multi-threaded loading aspect to eat a lot of losses, wasted a lot of time.

This time encountered in the input box input Chinese garbled problem. Search a lot of methods, have not found. No way. But know that the COCOS2DX 2.x version does not have this problem, so there is only follow-up code.

First find the dispatch message for WM_CHAR found in 2.x:

In CCEGLView.cpp in platform/win32/LRESULT cceglview::windowproc (UINT message, WPARAM WPARAM, LPARAM LPARAM) can be found,

Do not say, direct sticker code:

Case WM_CHAR: {if (WParam < 0x20) {if (Vk_back = = WParam)                 {Ccimedispatcher::shareddispatcher ()->dispatchdeletebackward (); } else if (Vk_return = = WParam) {ccimedispatcher::shareddispatcher ()-                 >dispatchinserttext ("\ n", 1);                 } else if (Vk_tab = = WParam) {//TAB input} else if (Vk_escape = = WParam) {//ESC input//ccdirector:                 : Shareddirector ()->end (); }} else if (WParam < +) {//ASCII char Ccimedis             Patcher::shareddispatcher ()->dispatchinserttext ((const char *) &wparam, 1);                 } else {char szutf8[8] = {0}; int NLEn = WideCharToMultiByte (Cp_utf8, 0, (LPCWSTR) &wparam, 1, SzUtf8, sizeof (SZUTF8), NULL, NULL);             Ccimedispatcher::shareddispatcher ()->dispatchinserttext (SzUtf8, Nlen); } if (M_lpfnaccelerometerkeyhook!=null) {(*m_lpfnaccelerometerkeyhook) (Message             , Wparam,lparam);  }} break;

As above: The most important comes up,

else if (WParam < +)             {                 //ASCII char                 ccimedispatcher::shareddispatcher ()->dispatchinserttext ( const char *) &wparam, 1);             }             else             {                 char szutf8[8] = {0};                 int nlen = WideCharToMultiByte (Cp_utf8, 0, (LPCWSTR) &wparam, 1, SzUtf8, sizeof (SZUTF8), NULL, NULL);                 Ccimedispatcher::shareddispatcher ()->dispatchinserttext (SzUtf8, Nlen);             

Here we can vaguely see that the Chinese garbled processing method:

Okay, get into our 3.2 version:

First look at the beginning of the main registration message event:

In the Glview::initwithrect:

    Glfwsetmousebuttoncallback (_mainwindow, glfweventhandler::onglfwmousecallback);
    Glfwsetcursorposcallback (_mainwindow, glfweventhandler::onglfwmousemovecallback);
    Glfwsetscrollcallback (_mainwindow, glfweventhandler::onglfwmousescrollcallback);
    glfwsetcharcallback (_mainwindow, Glfweventhandler::o Nglfwcharcallback);
    Glfwsetkeycallback (_mainwindow, Glfweventhandler::onglfwkeycallback );
    Glfwsetwindowposcallback (_mainwindow, Glfweventhandler::o Nglfwwindowposcallback);
    Glfwsetframebuffersizecallback (_mainwindow, Glfweventhandler::o nglfwframebuffersize);
    Glfwsetwindowsizecallback (_mainwindow, Glfweventhandler::o Nglfwwindowsizefuncallback);

The red above is what we want:

Enter Glfweventhandler::onglfwcharcallback, in follow up: _view->onglfwcharcallback (window, character);

OK: We go to the most critical location: Direct Sticker Code:

void Glview::onglfwcharcallback (Glfwwindow *window, unsigned int character) {Imedispatcher::shareddispatcher () Dispatchinserttext ((const char*) &character, 1);}

Does it have a similar place with 2.x?Yes, we use 2.x to deal with the problem of Chinese garbled, not much to say, directly see the results

void Glview::onglfwcharcallback (Glfwwindow *window, unsigned int character) {if (character < +) Imedispatcher:: Shareddispatcher ()->dispatchinserttext ((const char*) &character, 1); Else{char szutf8[8] = {0};int NLen = WideCharToMultiByte (Cp_utf8, 0, (LPCWSTR) &character, 1, SzUtf8, sizeof (SZUTF8), NULL, NULL); Imedispatcher:: Shareddispatcher ()->dispatchinserttext (SzUtf8, Nlen);}}

OK, finish! It's that simple, now you can try it, support Chinese input method (mainly for Windows platform)

in fact, one step: in 3.x to collect the cable

Glview::onglfwcharcallback

Then add the above function content, that is done.
