|

**Where is the documentation?**
|
||||
|
||||
- The documentation is at the top of imgui.cpp + effectively imgui.h.
|
||||
- Example code is in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() 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.
|
||||
- We obviously needs better documentation! Consider contributing or becoming a [Patron](http://www.patreon.com/imgui) to promote this effort.
|
||||
- Your programming IDE is your friend, find the type or function declaration to find comments associated to it.
|
||||
This library is poorly documented at the moment and expects of the user to be acquainted with C/C++.
|
||||
- Run the examples/ applications and explore them.
|
||||
- See demo code in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() function.

- The demo covers most features of Dear ImGui, so you can read the code and see its output.
|
||||
- See documentation and comments at the top of imgui.cpp + effectively imgui.h.

||||
- Dozens of standalone example applications using e.g. OpenGL/DirectX are provided in the examples/ folder to explain how to integrate Dear ImGui with your own engine/application.

**Which version should I get?**
|
||||
|
||||
I 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. Several projects are using this branch and it is kept in sync with master regularly.

**Why the odd dual naming, "Dear ImGui" vs "ImGui"?**
|
||||
|
||||
The library started its life as "ImGui" due to the fact that I didn't give it a proper name when I released 1.0 and had no particular expectation that it would taker off. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations (e.g. Unity uses it own implementation of the IMGUI paradigm). It seemed confusing and unfair to hog the name. To reduce the ambiguity without affecting existing codebases, I have decided on an alternate, longer name "Dear ImGui" that people can use to refer to this specific library in ambiguous situations. Please try to refer to it as "Dear ImGui".

FREQUENTLY ASKED QUESTIONS (FAQ), TIPS
|
||||
======================================
|
||||
|
||||
Q: Where is the documentation?
|
||||
A: This library is poorly documented at the moment and expects of the user to be acquainted with C/C++.
|
||||
- Run the examples/ and explore them.
|
||||
- See demo code in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() function.
|
||||
- The demo covers most features of Dear ImGui, so you can read the code and see its output.
|
||||
- See documentation and comments at the top of imgui.cpp + effectively imgui.h.
|
||||
- Dozens of standalone example applications using e.g. OpenGL/DirectX are provided in the examples/
|
||||
folder to explain how to integrate Dear ImGui with your own engine/application.
|
||||
- Your programming IDE is your friend, find the type or function declaration to find comments
|
||||
associated to it.
|
||||
|
||||
Q: Which version should I get?
|
||||
A: I 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 'docking' branch which includes:
|
||||
- Docking/Merging features (https://github.com/ocornut/imgui/issues/2109)
|
||||
- Multi-viewport features (https://github.com/ocornut/imgui/issues/1542)
|
||||
Many projects are using this branch and it is kept in sync with master regularly.
|
||||
|
||||
Q: Who uses Dear ImGui?
|
||||
A: See "Quotes" (https://github.com/ocornut/imgui/wiki/Quotes) and
|
||||

|

|

Q: How can I tell whether to dispatch mouse/keyboard to imgui or to my application?
|
||||
A: You can read the 'io.WantCaptureMouse', 'io.WantCaptureKeyboard' and 'io.WantTextInput' flags from the ImGuiIO structure (e.g. if (ImGui::GetIO().WantCaptureMouse) { ... } )
|
||||
- When 'io.WantCaptureMouse' is set, imgui wants to use your mouse state, and you may want to discard/hide the inputs from the rest of your application.
