I have been using Dear ImGui to develop a simple user interface for xemu, an Original Xbox Emulator. The most interesting pieces of this UI so far are probably the dynamic controller configuration dialog and the "About" dialog, which mix in some OpenGL-rendered elements for custom widgets. I have plans to build on this further, but I'm happy with the interface so far and I highly recommend Dear ImGui for similar projects.

Thank you Dear ImGui developers!

P.S. Along the way I also had to solve file navigation. For this I decided to leverage native file selection interfaces and ended up picking this simple library.

About a year and a half using ImGUI for the Overload 3D Game Engine!

A whole event-based UI module has been built on top of ImGUI:

// Simple window with a button printing "Hello World" when clicked
class MyWindow : PanelWindow
{
public:
    MyWindow()
    {
        auto& button = CreateWidget<OvUI::Widgets::Buttons::Button>("SayHello");
        button->ClickedEvent += []() { Debug.Log("Hello World!"); };
    }
};

// Keeps elementCount up-to-date with the elementCountField
class MyWindow : PanelWindow
{
public:
    MyWindow()
    {
        int elementCount = 0;
        auto& elementCountField = CreateWidget<OvUI::Widgets::InputFields::InputInt>("Element count:");
        auto& elementCountDispatcher = elementCountField.AddPlugin<OvUI::Plugins::DataDispatcher<int>>();
        elementCountDispatcher.RegisterReference(elementCount);
    }
};

// A simple text with a custom contextual menu (On right click)
class MySuperContextualMenu : public OvUI::Plugins::ContextualMenu
{
public:
    MySuperContextualMenu() = default;
    virtual void CreateList()
    {
        auto& open = CreateWidget<OvUI::Widgets::Menu::MenuItem>("Open");
        auto& edit = CreateWidget<OvUI::Widgets::Menu::MenuItem>("Edit");
        auto& properties = CreateWidget<OvUI::Widgets::Menu::MenuItem>("Properties");

        open.ClickedEvent += []() { DoStuff(); };
        edit.ClickedEvent += []() { DoOtherStuff(); };
        properties.ClickedEvent += []() { SoSomething(); };
    }
};

class MyWindow : PanelWindow
{
public:
    MyWindow()
    {
        auto& text = CreateWidget<OvUI::Widgets::Texts::Text>("Right-click me please!");
        text.AddPlugin<MySuperContextualMenu>();
    }
};

Editor UI

In-game debug UI

[tomasiser]

Hello! A bit over 1 year ago, we finished our student project called Pepr3D for 3D printing. Even though the project is not maintained anymore, I wanted to showcase our usage of ImGui here.

Essentially everything UI related in Pepr3D is using ImGui, even though it was heavily customized. We made a lot of use of functions like PushStyleVar, PushStyleColor, ButtonBehavior, CalcTextSize, RenderTextClipped, etc., which would otherwise take ages to implement ourselves. If anyone is curious, you can have a look into our /src/ui folder for source codes, especially SidePane and Toolbar.

Overall, I was really excited how easy it was to use ImGui and its API to create a completely new user interface that looks exactly as I wanted. It was a really great help that ImGui also implemented advanced functionalities like drag & dropping and color picking, which I used in our color palette management.

Here are a couple of gifs to showcase the UI. :-)

And showcasing the individual tools:

Paint bucket	Brush

Text editor	Export assistant

Hello!

here goes a project of mine in current development ( beta stage now ), called Mosaic, a livecoding programming/patching environment for creating real-time audio-visual compositions. It's principally designed for live needs, as can be teaching in class, live performing in an algorave, or running a generative audio-visual installation in a museum.
It aims to empower artists, creative coders, scenographers and other creative technologists in their creative workflow.
It's a FLOSS, Free/Libre and Open Source Software with multi-platform support, and it's written in C++, offering high performance.

His GUI ( node canvas, nodes, links, menus and everything ) is completely builded with the amazing Dear ImGui, coupled with openFrameworks for texture drawing.

Mosaic is shipped with an internal code editor, non-blocking system dialogs, a programmable non-linear interactive timeline, an included patch video exporter with subtitler for easy tutorial creation, lua/python/glsl/bash live-coding and pure data live-patching capability, a good selection of audio synthesis modules, multiple fullscreen output windows capabilities ( as many as your system can have ) with an independent warping for each window, a map-map style integrated mapping module, and an easy to use osc sending/receiving objects/nodes for network communication.

The idea behind Mosaic is to facilitate human-machine communication, to amplify imagination and to speed up the creative workflow, without sacrificing the spectrum of possibilities. To achieve this, it bundles together various creative-coding tools, acting as an interactive bridge between them.
It includes a collection of audio-visual objects that can be easily connected together using a nodal-based graphical interface, defining a custom dataflow.

Mosaic is mainly based on two frameworks : OpenFrameworks and ImGui. OpenFrameworks is an open source C++ toolkit for creative coding.
Dear ImGui is a bloat-free graphical user interface for C++ with minimal dependencies.
Together with the latter ones, Mosaic bundles comes with other 3rd party libraries such as PureData Vanilla and numerous ofxAddons.
It also embeds various programing languages for live-coding purposes : Lua with OF-bindings, Python 2.7 scripting interpreter, live compiling of GLSL shaders and editing/execute Bash scripts (macOS & linux) capabilities.

Mosaic is extendable : you can easily add custom objects.
While this involves writing and compiling code, requiring some C++ knowledge, we aim to make this process as easy as possible. Thus, Mosaic is flexible and devoted to grow over time.
For example, any Openframeworks project can be easily ported to Mosaic Objects, exposing them to the live-patching environment. This way, working with OF becomes way more modular, and you can make run-time adjustments. Possibilities are endless.
Once created, plugins can either be statically compiled into Mosaic, or if you wish, there's also support for dynamically loading them, making it easy to share and distribute your objects with others.

Mosaic is still under development and in Beta release, but has been already successfully used for 2 years at the Fine Arts faculty of the UPV university, Valencia, Spain. It has been deployed in multiple student projects presentations, and in some interactive installation in public cultural spaces.

Today, Mosaic has sufficiently grown to be tested by a wider group of people.

If you're curious, please try out Mosaic and don't hesitate to get in touch.
Mosaic is open to anybody, contributions of any kind are welcome.

Mosaic development team is composed by Emanuele Mazza [https://github.com/d3cod3] Daan de Lange [https://daandelange.com/] and Maria José Martínez de Pisón

@thedmd: " I'm developing more concrete blueprint example for node editor. This one does real job behind the nodes.
It will land on main branch as an example when I decide it is decent enough. You can look at the code right now on https://github.com/thedmd/imgui-node-editor/tree/develop branch. Code is in flux so a lot can change yet."

@kudaba "That's pretty much what I have in my node system (users can very easily describe new nodes and graphs in c++ with the graphs able to compile into efficient run-time)"

Dear ImGUI is so cool that I put imgui into a layered child window.

Say goodbye to MFC, emWin, ucGUI, microWindows, Kivy, Qt, RIP!

Thank you! Dear ImGUI.

[jspanchu]

I set up an initial implementation to render VTK's display frame buffer into an ImGUI window (with ImGui::Image). Nothing fancy, but pretty cool. Now all of VTK's dataset manipulation/visualization capabilities can be realized in a project that uses DearImGUI for its UI. Note: Until now VTK was restricted to QT/MFC.

Supported VTK version >= 9.0.0

Source: Repo

Usage is straightforward for DearImGUI users:

Platform init
renderer backend init
ImGui_ImplVTK_Init() 
ImGui_ImplVTK_AddActor(..)
while(!terminate)
{
  ImGui::NewFrame()
  ...
  ImGui_ImplVTK_Render()
  ImGui::Render()
  ImGui_ImplXXXX_RenderDrawData(ImGui::GetDrawData());
}

Memory watcher for my GBA emulator
It's very WIP and I'm trying to make it look better :P
The reason for me making it from scratch is that the memory watcher extension for ImGui dies when feeding him with address spaces that are larger than 24 bit (IIRC, at least that's what has happened to me and some other emulator developers), and since the GBA has an address space that ranges from 28 to 32 bit, here I am :3

New feature in ImGuiFontStudio

The ability to generate a "Card" of the font. Who will show you Glyph and Corresponding Label.

So, when you not have in mind, the visual of an icon in your header file, no need to reopen ImGuiFontStudio,
you can just check the "Card" file

see this tweet for a video : https://twitter.com/aiekick/status/1346005440954585088

and here a sample Card of the whole font icon Forkawesome

During the lockdown we had for months in Melbourne, I started to rewrite the entire GUI portion of the custom software we use to Create Interactive Installations. Not a small task, but it brings a breath of fresh air to our software, and moves the software to have a multi-platform Editor Environment, instead of being stuck to windows.

Soprano - Build and visualize Minecraft chat components

Minecraft has a system of "chat components", which is essentially used to serialize rich-text into JSON, in order to network it to clients to render. All the more detailed aspects of this are out of the scope of this thread, but the dear imgui editor certainly isn't.

https://www.youtube.com/watch?v=fwx7Q3TCccU
This shows the use of a live editor, where the changes you make are displayed directly to you. This helps facilitate the manual creation of these chat components, which can be used for a multitude of reasons.

Another interesting point to discuss is the window -- it's a dear imgui decorated window, with no visible platform window. I spoke about wanting to do this in #3680, and this was the result of the suggestions from @\rokups. Truly a very weird use-case, but I personally believe it came out looking incredible.

The only problem currently is text wrapping being incorrect. TextWrapped is called for each component (each JSON object with the text property), and ImGui::SameLine(0.0f, 0.0f) is used to keep all the text next to each other. However, if the text wraps, it will wrap under the start of that individual TextWrapped call, instead of the very first one -- which is the parent. I'm not sure if dear imgui has a simple solution to let me specify text wrapping coordinates/offsets...

I thought using ImGui for cheats in kinda ..disallowed?

[ocornut]

You can use it for anything a per the license, but asking for any form of support is disallowed, yes.

[MoneyWasted]

I think we all know that most of imguis use is in cheats or other types of game modifications. Not saying all uses are used that way as there are people using it for other things.

It's nice to have all your options in a menu that can be pulled up in the game rather then using key binds or a console window.

At least ocornut is understanding and allows us to use imgui in our menus and for that I thank you.

Most Imgui uses I've seen are not used for cheats
Though you're the only cheat dev using ImGui, that seems to be quite skilled
The gui looks very nice

Aiekick we are happy of your software’s progress but you posted here 7 times this month. It’d be good to keep your posts more spaced to make those Gallery threads varied and interesting for a maximum of followers. That said, we have just opened a new Discussions section here: https://github.com/ocornut/imgui/discussions and there’s a Show & Tell section there. feel free to create a topic for your software there. Thank you!

A ffmpeg-based video encoding tool built with imgui.

Nice! I want to build a "classical dialog GUI", similar to this, but all examples I find use the "lots of windows inside the main window" layout. I have looked to this project sources, but I do not understand Go... any other example in C++ on how to achieve this?

[mat-r]

I am also interested in an example in C++ to build this type of UI (only one window).

[aiekick]

you just need to hide the decoration of the window.
but this topic is not made for speak about that kind of things, just for share imgui use,
so please please use discord, github issue or github discussions for ask help

[Hoek67]

Just started to look at IMGui yesterday... and it's exactly what I was after. I was on the verge of looking at building my own before I discovered it.

Others were either full of bloat or had so many dependencies it was crazy.

My game engine was a DX7 one in 2004 and I recently upgraded to DX11 including learning HLSL etc from scratch. After a while I decided to use the DX7 code as a learning experience and start fresh.

The screenshot shows my initial evaluation effort. It actually hooked into my engine with ease as, like advertised the data from ImGui is basically a textured triangle list with clipping and texture breaks.

I hope the engine I'm making can be used as an educational tool eventually. Making a 3d rendered space invaders as a proof of concept of which I would supply source code.
