Homebrew RELEASE Simple application using ImGUI (libnx)

[mstrVLT]

A small example for easy development

ImGUI for SDL2
https://github.com/MstrVLT/switch_imgui_sdl2

ImGUI for GLFW (most devs prefer GLFW over SDL2)
https://github.com/MstrVLT/switch_imgui_glfw

Touchscreen is supported
Shared-font + ext example included

ImGui::ShowDemoWindow() function will create a demo window showcasing variety of features and examples.
The code is always available for reference in imgui_demo.cpp

Special thx: Pablo Curiel, Cpasjuste, SciresM, yellows8, fincs and all SwitchBrew members

Thanks friend, this is very useful for my apps.

In your project, you disable next/prev focus keys and unfortunately this is vital to change from window to window using a gamepad. You can look at my repo here https://github.com/notnotme/osp if you want to add mouse emulation using the gamepad (wich is much better than gamepad control in my opinion). The code is in sdl2_impl.cpp.

Good luck

Good luck

switch_imgui/source/imgui/imgui_impl_sdl.cpp button mapping is wrong for switch i recomend edit it

Spoiler

MAP_BUTTON(ImGuiNavInput_Cancel, SDL_CONTROLLER_BUTTON_A); // Circle / B
MAP_BUTTON(ImGuiNavInput_Menu, SDL_CONTROLLER_BUTTON_X); // Square / X
MAP_BUTTON(ImGuiNavInput_Input, SDL_CONTROLLER_BUTTON_Y); // Triangle / Y
MAP_BUTTON(ImGuiNavInput_DpadLeft, SDL_CONTROLLER_BUTTON_DPAD_LEFT); // D-Pad Left
MAP_BUTTON(ImGuiNavInput_DpadRight, SDL_CONTROLLER_BUTTON_DPAD_RIGHT); // D-Pad Right
MAP_BUTTON(ImGuiNavInput_DpadUp, SDL_CONTROLLER_BUTTON_DPAD_UP); // D-Pad Up
MAP_BUTTON(ImGuiNavInput_DpadDown, SDL_CONTROLLER_BUTTON_DPAD_DOWN); // D-Pad Down
MAP_BUTTON(ImGuiNavInput_FocusPrev, SDL_CONTROLLER_BUTTON_LEFTSHOULDER); // L1 / LB
MAP_BUTTON(ImGuiNavInput_FocusNext, SDL_CONTROLLER_BUTTON_RIGHTSHOULDER); // R1 / RB
MAP_BUTTON(ImGuiNavInput_TweakSlow, SDL_CONTROLLER_BUTTON_LEFTSHOULDER); // L1 / LB
MAP_BUTTON(ImGuiNavInput_TweakFast, SDL_CONTROLLER_BUTTON_RIGHTSHOULDER); // R1 / RB
MAP_BUTTON(ImGuiNavInput_Activate, SDL_CONTROLLER_BUTTON_B); // Cross / A

Use touch screen for change focus (or hold "Y" and click L trigger)
My touch implementation is bad, but better than nothing

for keyboard input you can use this piece of code but I did not manage to achieve good results)

Spoiler

            if (io.WantTextInput != prevWantInputText) {
                prevWantInputText = io.WantTextInput;
                if (io.WantTextInput)
                {
                    SwkbdConfig kbd;
                    Result rc;

                    // char input_kbd[255] = input;
 
                    rc = swkbdCreate(&kbd, 0);
                    if (R_SUCCEEDED(rc)) {
                        swkbdConfigMakePresetDefault(&kbd);
                        swkbdConfigSetInitialText(&kbd, input);
                        rc = swkbdShow(&kbd, input, sizeof(input));
                      
                       io.AddInputCharactersUTF8(input);

                        swkbdClose(&kbd);
                    }
                }
            }

Thanks you, if I need keyboard input in one of my apps I'll come back here to use this as a starting point to implement soft keys. I really appreciate.
About the gamepad mapping, I saw it was wrong for switch and edited it too.

My touch implementation is bad, but better than nothing

Mine is not better, act only as simple click, you can't scroll.

Touch screen fixed! Get new version here https://github.com/MstrVLT/switch_imgui
See this issue for best result! https://github.com/ocornut/imgui/issues/2334

 

[HookedBehemoth]

btw mtheall has made a deko3d wrapper for imgui

https://github.com/mtheall/ftpd/tree/master/source/imgui

 

[mstrVLT]

Add support for nx std + ext font )
