You should be able to build the examples from sources (tested on Windows/Mac/Linux). If you don't, let us know! If you want to have a quick look at some Dear ImGui features, you can download Windows binaries of the demo app here:
|
||||
- [imgui-demo-binaries-20190715.zip](http://www.dearimgui.org/binaries/imgui-demo-binaries-20200412.zip) (Windows binaries, 1.76, built 2020/04/12, master branch) or [older demo binaries](http://www.dearimgui.org/binaries).

|
||||
|
||||
The demo applications are not DPI aware so expect some blurriness on a 4K screen. For DPI awareness in your application, you can load/reload your font at different scale, and scale your style with `style.ScaleAllSizes()` (see [FAQ](https://www.dearimgui.org/faq)).

We occasionally tag [Releases](https://github.com/ocornut/imgui/releases) but it is generally safe and recommended to sync to master/latest. The library is fairly stable and regressions tend to be fixed fast when reported.
|
||||
|
||||
You may also peak at the [Multi-Viewport](https://github.com/ocornut/imgui/issues/1542) and [Docking](https://github.com/ocornut/imgui/issues/2109) features in the `docking` branch. Many projects are using this branch and it is kept in sync with master regularly.
|
||||
Advanced users may want to use the `docking` branch with [Multi-Viewport](https://github.com/ocornut/imgui/issues/1542) and [Docking](https://github.com/ocornut/imgui/issues/2109) features. This branch is kept in sync with master regularly.
