Display seems ok, but it looks like your user code (maybe OF code) isn't passing the correct inputs to io->AddInputCharacter().

oF use glfw, but not official version

void BaseEngine::onKeyPressed(ofKeyEventArgs& event)
{
    int key = event.keycode;
    io->KeysDown[key] = true;
    io->AddInputCharacter((unsigned short)event.codepoint);
    //io->AddInputCharactersUTF8((char*)event.codepoint);
}

codepoint in KeyEvent

/// \brief The Unicode code point you'd expect if this key combo (including modifier keys) was pressed in a text editor, or -1 for non-printable characters. 
unsigned int codepoint;

By the way, in this image, I haven't press space, that means "???????" is my composition text, not my final select text.

yes, codepoint not right.

I should use glfwSetCharCallback() instead

auto ptr = static_cast<ofAppGLFWWindow*>(ofGetWindowPtr());
glfwSetCharCallback(ptr->getGLFWWindow(), ImGui_ImplGlfwGL3_CharCallback);

You may want to log out the value that are passed to AddInputCharacter().
BaseEngine::onKeyPressed isn't GLFW so there must be some sort of translations happening.

Cool. Maybe report it to the OF ImGui extension https://github.com/jvcleave/ofxImGui/ or OpenFrameworks.

Note that raw GLFW 3.0 still has various issues with IME.
For example I have suggested this fix: glfw/glfw#41 (comment)
Without it I get the final "Enter" keypress of validating IME input to be fed into ImGui code. But there are other issues discussed and in the work.

Do you means that if I press “Enter" to confirm my selection ImGui will add "Enter" code to buffer string?

@ocornut

ocornut commented Jan 5, 2016

In some instances, if you press Enter to confirm your IME input, GLFW also pass an Enter keypress to your application via the callback. Normally the application shouldn't receive this Enter keypress.

Geistyp commented Jan 5, 2016

Yes, this issue exist in oF's glfw too. "Enter" code add to buffer, new input won't add to buffer now, unless I backspace that 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;
        }

oF already translate char to unicode, but ImGui need original char.

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

That translation in the WM_KEYDOWN/WM_SYSKEYDOWN handler is probably incorrect in case of IME use.

@ocornut sorry to ask here, is there any example to save/load gui para? I want to save/load all UI para include this chinese input text.
I've read your post here https://forum.libcinder.org/topic/imgui#23286000002477025

I plan to use ofParameterGroup to store this, but first I need to get all UI element.
I try getstate from my window, but get empty data

ImGuiStorage* tmp = ImGui::GetStateStorage();

ocornut commented Jan 8, 2016

This is quite out of the scope of what ImGui does.
I am not sure what you are trying to save exactly, what you mean by "all UI element". ImGui hold very little state, All the values, or whatever you refer to what "chinese input text" are user data, not ImGui data. The ImGuiStorage structure is typically used to store if a tree node was opened or closed.

Geistyp commented Jan 8, 2016

Simply I want to save all slider value.

Some other GUI library has save/load feature, so I wonder if ImGui have. I will go deep into ImGui to find a better way for my project. :)

ocornut commented Jan 8, 2016

The question doesn't make sense: ImGui doesn't know anything about your slider values. It isn't keeping any state. The values are all your data, not ImGUi data. This is the essential component of an IMGUI design.

imgui just handle only WM_CHAR on unicode window correctly.
you should rehandle WM_CHAR or change the way creating window.

    Replace BeginMenu/MenuItem swapping g.NavWindow with a more adequate ImGuiItemFlags_NoWindowHoverableCheck.
    Expecting more subtle issues to stem from this.
    Note that NoWindowHoverableCheck is not supported by IsItemHovered() but then IsItemHovered() on BeginMenu() never worked: fix should be easy in BeginMenu() + add test is IsItemHovered(), will do later

    Various comments

    As it turns out, functions like IsItemHovered() won't work on an open BeginMenu() because LastItemData is overriden by BeginPopup(). Probably an easy fix.

    IO: remove ImGuiInputEvent::IgnoredAsSame (revert part of 839c310), will filter earlier in next commit. (ocornut#5599)

    Making it a separate commit as this leads to much indentation change.

    Menus, Nav: Fixed using left/right navigation when appending to an existing menu (multiple BeginMenu() call with same names). (ocornut#1207)

commit 3532ed1
Author: ocornut <omarcornut@gmail.com>
Date:   Thu Sep 29 18:07:35 2022 +0200

    Menus, Nav: Fixed keyboard/gamepad navigation occasionally erroneously landing on menu-item in parent when the parent is not a popup. (ocornut#5730)

    Replace BeginMenu/MenuItem swapping g.NavWindow with a more adequate ImGuiItemFlags_NoWindowHoverableCheck.
    Expecting more subtle issues to stem from this.
    Note that NoWindowHoverableCheck is not supported by IsItemHovered() but then IsItemHovered() on BeginMenu() never worked: fix should be easy in BeginMenu() + add test is IsItemHovered(), will do later

    Various comments

    As it turns out, functions like IsItemHovered() won't work on an open BeginMenu() because LastItemData is overriden by BeginPopup(). Probably an easy fix.

    Refactor CalcWordWrapPositionA() to take on the responsability of minimum character display. Add CalcWordWrapNextLineStartA(), simplify caller code.

    Should be no-op but incrementing IMGUI_VERSION_NUM just in case.
