ofKeyEventArgs.codepoint not right when use IME input

[jvcleave]

I think there may be some Unicode/UTF-8 in OF 0.9.0

Take a look at this and see if it may help
http://blog.openframeworks.cc/post/133404738514/openframeworks-090-ofthreadchannel-utf-8-and

Especially the section about ofAppendUTF8(str,key)

[Geistyp]

Yes, but ImGui combine key code to string and parse to utf8, we just use AddInputCharacter to add key code.

https://github.com/arturoc/glfw/blob/feature-keysUnicode/src/win32_window.c#L320

        case WM_SYSKEYDOWN:
        {
            const int scancode = (lParam >> 16) & 0x1ff;
            const int key = translateKey(wParam, lParam);
            if (key == _GLFW_KEY_INVALID)
                                break;
                        const int unicode = translateToUnicode(wParam,scancode);

                        _glfwInputKey(window, key, scancode, unicode, GLFW_PRESS, getKeyMods());
            break;
        }

        case WM_CHAR:
        {
            _glfwInputChar(window, (unsigned int) wParam, getKeyMods(), GL_TRUE);
            return 0;
        }

        case WM_SYSCHAR:
        {
            _glfwInputChar(window, (unsigned int) wParam, getKeyMods(), GL_FALSE);
            return 0;
        }

        case WM_UNICHAR:
        {
            // This message is not sent by Windows, but is sent by some
            // third-party input method engines

            if (wParam == UNICODE_NOCHAR)
            {
                // Returning TRUE here announces support for this message
                return TRUE;
            }

            _glfwInputChar(window, (unsigned int) wParam, getKeyMods(), GL_TRUE);
            return FALSE;
        }

oF already translate char to unicode, but ImGui input just need (unsigned int) wParam

There is no different change to use glfwSetCharCallback(), but add features to support IME input.

ok - I think I understand. I will take a look

@Geistyp

static char buf[256] = "";
        bool isinput = ImGui::InputText(ofLocaleToUtf8("输入中文").c_str(), buf, IM_ARRAYSIZE(buf));
        if (isinput)
        {
            ofLogNotice(  ofToString(buf) );
        }

display Garbled

[o2co2]

@Geistyp How to convert static char buf[256]

[Geistyp]

@o2co2 what do you mean?
Is that "输入中文" garbled? or your IME input garbled?

[o2co2]

@Geistyp see the picture

[Geistyp]

@o2co2
console output chinese? try setlocale(LC_ALL, "chs");

[o2co2]

@Geistyp Thank you

static char buf[256] = "";
bool isinput = ImGui::InputText(ofLocaleToUtf8("输入中文").c_str(), buf, IM_ARRAYSIZE(buf));
if (isinput)
{
      std::wstring sw = UTF8ToUnicode(ofToString(buf));
      std::string uToa = UnicodeToANSI(sw);
      ofLogNotice(uToa.c_str());
}
