// dear imgui, v1.92.9 WIP

// (demo code)

// Help:

// - Read FAQ at http://dearimgui.com/faq

// - Call and read ImGui::ShowDemoWindow() in imgui_demo.cpp. All applications in examples/ are doing that.

// - Need help integrating Dear ImGui in your codebase?

//   - Read Getting Started https://github.com/ocornut/imgui/wiki/Getting-Started

//   - Read 'Programmer guide' in imgui.cpp for notes on how to setup Dear ImGui in your codebase.

// Read top of imgui.cpp and imgui.h for many details, documentation, comments, links.

// Get the latest version at https://github.com/ocornut/imgui

// How to easily locate code?

// - Use Tools->Item Picker to debug break in code by clicking any widgets: https://github.com/ocornut/imgui/wiki/Debug-Tools

// - Browse pthom's online imgui_explorer: web version the demo w/ source code browser: https://pthom.github.io/imgui_explorer

// - Find a visible string and search for it in the code!

//---------------------------------------------------

// PLEASE DO NOT REMOVE THIS FILE FROM YOUR PROJECT!

//---------------------------------------------------

// Message to the person tempted to delete this file when integrating Dear ImGui into their codebase:

// Think again! It is the most useful reference code that you and other coders will want to refer to and call.

// Have the ImGui::ShowDemoWindow() function wired in an always-available debug menu of your game/app!

// Also include Metrics! ItemPicker! DebugLog! and other debug features.

// Removing this file from your project is hindering access to documentation for everyone in your team,

// likely leading you to poorer usage of the library.

// Everything in this file will be stripped out by the linker if you don't call ImGui::ShowDemoWindow().

// If you want to link core Dear ImGui in your shipped builds but want a thorough guarantee that the demo will not be

// linked, you can setup your imconfig.h with #define IMGUI_DISABLE_DEMO_WINDOWS and those functions will be empty.

// In another situation, whenever you have Dear ImGui available you probably want this to be available for reference.

// Thank you,

// -Your beloved friend, imgui_demo.cpp (which you won't delete)

//--------------------------------------------

// ABOUT THE MEANING OF THE 'static' KEYWORD:

//--------------------------------------------

// In this demo code, we frequently use 'static' variables inside functions.

// A static variable persists across calls. It is essentially a global variable but declared inside the scope of the function.

// Think of "static int n = 0;" as "global int n = 0;" !

// We do this IN THE DEMO because we want:

// - to gather code and data in the same place.

// - to make the demo source code faster to read, faster to change, smaller in size.

// - it is also a convenient way of storing simple UI related information as long as your function

//   doesn't need to be reentrant or used in multiple threads.

// This might be a pattern you will want to use in your code, but most of the data you would be working

// with in a complex codebase is likely going to be stored outside your functions.

//-----------------------------------------

// ABOUT THE CODING STYLE OF OUR DEMO CODE

//-----------------------------------------

// The Demo code in this file is designed to be easy to copy-and-paste into your application!

// Because of this:

// - We never omit the ImGui:: prefix when calling functions, even though most code here is in the same namespace.

// - We try to declare static variables in the local scope, as close as possible to the code using them.

// - We never use any of the helpers/facilities used internally by Dear ImGui, unless available in the public API.

// - We never use maths operators on ImVec2/ImVec4. For our other sources files we use them, and they are provided

//   by imgui.h using the IMGUI_DEFINE_MATH_OPERATORS define. For your own sources file they are optional

//   and require you either enable those, either provide your own via IM_VEC2_CLASS_EXTRA in imconfig.h.

//   Because we can't assume anything about your support of maths operators, we cannot use them in imgui_demo.cpp.

// Navigating this file:

// - In Visual Studio: Ctrl+Comma ("Edit.GoToAll") can follow symbols inside comments, whereas Ctrl+F12 ("Edit.GoToImplementation") cannot.

// - In Visual Studio w/ Visual Assist installed: Alt+G ("VAssistX.GoToImplementation") can also follow symbols inside comments.

// - In VS Code, CLion, etc.: Ctrl+Click can follow symbols inside comments.

// - You can search/grep for all sections listed in the index to find the section.
