Cython-based Python bindings for dear imgui

Project description

completion Coverage Status Documentation Status


  • Build status (Windows)
  • Build Status (OS X & Linux)

This is a fork of, which contains the following improvements over upstream:

  • Newer version of ImGui, the docking branch is used. This is needed to get some PushID fixes.
  • DockSpace and some auxilliary methods and enum values
  • Optimized polyline rendering using NumPy
  • is_key_pressed function
  • ImDrawIdx is configured as unsigned int, enabling bigger draw lists.
  • AddConvexPolyFilled function
  • Batch draw multiple polylines and filled polygons using NumPy arrays
  • System clipboard integration in the GLFW integration layer
  • Add the _IO.ini_filename setter & getter
  • Fix a crash on two ImGui contexts in one app, one afther another. The _io global wasn't refreshed properly on destroy_content.
  • Add a function to create custom font glyph ranges. Enable font merging.
  • Add support for Unicode characters > 0xFFFF. This required #define IMGUI_USE_WCHAR32.

These are needed for

This fork does not, however, provide pre-built packages, nor documentation on Code quality & documentation standards are not as high as upstream. It is advisable to use the upstream package for any work that does not require Concur.


Python bindings for the amazing dear imgui C++ library - a Bloat-free Immediate Mode Graphical User Interface.



pyimgui is available on PyPI so you can easily install it with pip:

pip install imgui[full]

Above command will install imgui package with additional dependencies for all built-in rendering backend integrations (pygame, cocos2d, etc.). If you don't want to install all additional dependencies you can always use bare pip install imgui command or select a specific set of extra requirements:

  • for pygame backend use pip install imgui[pygame]
  • for GLFW3 backend use pip install imgui[glfw]
  • for SDL2 backend use pip install imgui[sdl2]
  • for Cocos2d backend use pip install imgui[cocos2d]
  • for pyglet backend use pip install imgui[pyglet]

Package is distributed in form of built wheels so it does not require compilation on most operating systems. For more details about compatibility with diffferent OSes and Python versions see the Project ditribution section of this documentation page.

Project status

The imgui package provides support for the majority of core ImGui widgets and functionalities. Some low-level API elements and complex widgets (like plots) may be missing. We are working hard to provide 100% feature mapping of the core ImGui library. The completion badge shows up-to-date status of that goal.

Project distribution

This project has working build pipeline on Appveyor and Travis and builds succesfully for all major operating systems with different architectures:

  • Windows (32bit & 64bit)
  • Linux (32bit & 64bit)
  • OS X (universal build)

Right now we are ready to shipping the built wheels for these three systems (even for Linux using manylinux1 wheels). The build pipeline covers multiple Python versions:

  • py27
  • py33
  • py34
  • py35
  • py36

pyimgui provides documentation with multiple visual examples. Thanks to custom Sphinx extensions we are able to render GUI examples off screen directly from docstring snippets. These examples work also as automated functional tests. Documentation is hosted on

If none of these wheels work in your environment you can install the imgui package by compiling it directly from sdist distribution using one of following commands:

# will install Cython as extra dependency and compile from Cython sources
pip install imgui[Cython] --no-binary imgui

# will compile from pre-generated C++ sources
pip install imgui --no-binary imgui

Development tips

We have tried hard to make the process of bootstrapping this project as simple as possible.

In order to build and install project locally ,ake sure you have created and activated virtual environment using virtualenv or python -m venv (for newer Python releases). Then you can just run:

make build

This command will bootstrap whole environment (pull git submodules, install dev requirements etc.) and build the project. make will automatically install imgui in the development/editable mode. Then you can run some examples found in the doc/examples directory in order to verify if project is working.

For building documentation and running tests you will need some additional requirements from doc/requirements-test.txt.

You can run tests with:


If you have any problems with building or installing the project just ask us for help by creating GitHub issue.
