You should be able to build the examples from sources (tested on Windows/Mac/Linux). If you don't, let me know! If you want to have a quick look at the features of ImGui, you can download Windows binaries of the demo app here.
- [imgui-demo-binaries-20161113.zip](http://www.miracleworld.net/imgui/binaries/imgui-demo-binaries-20161113.zip) (Windows binaries, ImGui 1.49+ 2016/11/13, 5 executables, 588 KB)
Bindings
--------
_NB: those third-party bindings may be more or less maintained, more or less close to the spirit of original API. People who create language bindings sometimes haven't used the C++ API themselves. ImGui was designed with C++ in mind and some of the subtleties may be lost in translation with other languages. If your language supports it, I would suggest replicating the function overloading and default parameters used in the original, else the API may be harder to use. In doubt, always check the original C++ version first!_
Languages:
- cimgui: thin c-api wrapper for ImGui https://github.com/Extrawurst/cimgui

Check the "API BREAKING CHANGES" sections for a list of occasional API breaking changes. If you have a problem with a function, search for its name
in the code, there will likely be a comment about it. Please report any issue to the GitHub page!
Q: What is ImTextureID and how do I display an image?
A: ImTextureID is a void* used to pass renderer-agnostic texture references around until it hits your render function.
ImGui knows nothing about what those bits represent, it just passes them around. It is up to you to decide what you want the void* to carry!

ISSUES & TODO-LIST
==================
Issue numbers (#) refer to github issues listed at https://github.com/ocornut/imgui/issues
The list below consist mostly of notes of things to do before they are requested/discussed by users (at that point it usually happens on the github)
The list below consist mostly of ideas noted down before they are requested/discussed by users (at which point it usually moves to the github)
- doc: add a proper documentation+regression testing system (#435)
- window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. perhaps a lightweight explicit cleanup pass.
