- The documentation is at the top of imgui.cpp + effectively imgui.h.
- The documentation is at the top of imgui.cpp + effectively imgui.h.
- Example code is in imgui_demo.cpp and particularly the ImGui::ShowTestWindow() function. It covers most features of ImGui so you can read the code and call the function itself to see its output.
- Standalone example applications using e.g. OpenGL/DirectX are provided in the examples/ folder.
- It obviously needs better documentation! Consider helping or becoming a [Patron](http://www.patreon.com/imgui) to promote this effort.
<b>How do you use ImGui on a platform that may not have a mouse or keyboard?</b>
I recommend using [Synergy](http://synergy-project.org) ([sources](https://github.com/synergy/synergy)). In particular, the _src/micro/uSynergy.c_ file contains a small client that you can use on any platform to connect to your host PC. You can seamlessly use your PC input devices from a video game console or a tablet. ImGui allows to increase the hit box of widgets (via the _TouchPadding_ setting) to accommodate a little for the lack of precision of touch inputs, but it is recommended you use a mouse to allow optimising for screen real-estate.
<b>How do I update to a newer version of ImGui?</b>
<br><b>Can I have multiple widgets with the same label? Can I have widget without a label? (Yes)</b>
<br><b>I integrated ImGui in my engine and the text or lines are blurry..</b>
<br><b>I integrated ImGui in my engine and some elements are disappearing when I move windows around..</b>
<br><b>How can I load a different font than the default?</b>

See the FAQ in imgui.cpp for answers.
In your Render function, try translating your projection matrix by (0.5f,0.5f) or (0.375f,0.375f). Also make sure your orthographic projection matrix and io.DisplaySize matches your actual framebuffer dimension.

Most likely you are mishandling the clipping rectangles in your render function. Rectangles provided by ImGui are defined as (x1,y1,x2,y2) and NOT as (x1,y1,width,height).
