// dear imgui, 1.88 WIP // (main code and documentation) // Help: // - Read FAQ at http://dearimgui.org/faq // - Newcomers, read 'Programmer guide' below for notes on how to setup Dear ImGui in your codebase. // - Call and read ImGui::ShowDemoWindow() in imgui_demo.cpp. All applications in examples/ are doing that. // Read imgui.cpp for details, links and comments. // Resources: // - FAQ http://dearimgui.org/faq // - Homepage & latest https://github.com/ocornut/imgui // - Releases & changelog https://github.com/ocornut/imgui/releases // - Gallery https://github.com/ocornut/imgui/issues/4451 (please post your screenshots/video there!) // - Wiki https://github.com/ocornut/imgui/wiki (lots of good stuff there) // - Glossary https://github.com/ocornut/imgui/wiki/Glossary // - Issues & support https://github.com/ocornut/imgui/issues // Getting Started? // - For first-time users having issues compiling/linking/running or issues loading fonts: // please post in https://github.com/ocornut/imgui/discussions if you cannot find a solution in resources above. // Developed by Omar Cornut and every direct or indirect contributors to the GitHub. // See LICENSE.txt for copyright and licensing details (standard MIT License). // This library is free but needs your support to sustain development and maintenance. // Businesses: you can support continued development via invoiced technical support, maintenance and sponsoring contracts. Please reach out to "contact AT dearimgui.com". // Individuals: you can support continued development via donations. See docs/README or web page. // It is recommended that you don't modify imgui.cpp! It will become difficult for you to update the library. // Note that 'ImGui::' being a namespace, you can add functions into the namespace from your own source files, without // modifying imgui.h or imgui.cpp. You may include imgui_internal.h to access internal data structures, but it doesn't // come with any guarantee of forward compatibility. Discussing your changes on the GitHub Issue Tracker may lead you // to a better solution or official support for them. /* Index of this file: DOCUMENTATION - MISSION STATEMENT - END-USER GUIDE - PROGRAMMER GUIDE - READ FIRST - HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI - GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE - HOW A SIMPLE APPLICATION MAY LOOK LIKE - HOW A SIMPLE RENDERING FUNCTION MAY LOOK LIKE - USING GAMEPAD/KEYBOARD NAVIGATION CONTROLS - API BREAKING CHANGES (read me when you update!) - FREQUENTLY ASKED QUESTIONS (FAQ) - Read all answers online: https://www.dearimgui.org/faq, or in docs/FAQ.md (with a Markdown viewer) CODE (search for "[SECTION]" in the code to find them) // [SECTION] INCLUDES // [SECTION] FORWARD DECLARATIONS // [SECTION] CONTEXT AND MEMORY ALLOCATORS // [SECTION] USER FACING STRUCTURES (ImGuiStyle, ImGuiIO) // [SECTION] MISC HELPERS/UTILITIES (Geometry functions) // [SECTION] MISC HELPERS/UTILITIES (String, Format, Hash functions) // [SECTION] MISC HELPERS/UTILITIES (File functions) // [SECTION] MISC HELPERS/UTILITIES (ImText* functions) // [SECTION] MISC HELPERS/UTILITIES (Color functions) // [SECTION] ImGuiStorage // [SECTION] ImGuiTextFilter // [SECTION] ImGuiTextBuffer // [SECTION] ImGuiListClipper // [SECTION] STYLING // [SECTION] RENDER HELPERS // [SECTION] MAIN CODE (most of the code! lots of stuff, needs tidying up!) // [SECTION] INPUTS // [SECTION] ERROR CHECKING // [SECTION] LAYOUT // [SECTION] SCROLLING // [SECTION] TOOLTIPS // [SECTION] POPUPS // [SECTION] KEYBOARD/GAMEPAD NAVIGATION // [SECTION] DRAG AND DROP // [SECTION] LOGGING/CAPTURING // [SECTION] SETTINGS // [SECTION] VIEWPORTS // [SECTION] PLATFORM DEPENDENT HELPERS // [SECTION] METRICS/DEBUGGER WINDOW // [SECTION] OTHER DEBUG TOOLS (ITEM PICKER, STACK TOOL) */ //----------------------------------------------------------------------------- // DOCUMENTATION //----------------------------------------------------------------------------- /* MISSION STATEMENT ================= - Easy to use to create code-driven and data-driven tools. - Easy to use to create ad hoc short-lived tools and long-lived, more elaborate tools. - Easy to hack and improve. - Minimize setup and maintenance. - Minimize state storage on user side. - Portable, minimize dependencies, run on target (consoles, phones, etc.). - Efficient runtime and memory consumption. Designed for developers and content-creators, not the typical end-user! Some of the current weaknesses includes: - Doesn't look fancy, doesn't animate. - Limited layout features, intricate layouts are typically crafted in code. END-USER GUIDE ============== - Double-click on title bar to collapse window. - Click upper right corner to close a window, available when 'bool* p_open' is passed to ImGui::Begin(). - Click and drag on lower right corner to resize window (double-click to auto fit window to its contents). - Click and drag on any empty space to move window. - TAB/SHIFT+TAB to cycle through keyboard editable fields. - CTRL+Click on a slider or drag box to input value as text. - Use mouse wheel to scroll. - Text editor: - Hold SHIFT or use mouse to select text. - CTRL+Left/Right to word jump. - CTRL+Shift+Left/Right to select words. - CTRL+A our Double-Click to select all. - CTRL+X,CTRL+C,CTRL+V to use OS clipboard/ - CTRL+Z,CTRL+Y to undo/redo. - ESCAPE to revert text to its original value. - Controls are automatically adjusted for OSX to match standard OSX text editing operations. - General Keyboard controls: enable with ImGuiConfigFlags_NavEnableKeyboard. - General Gamepad controls: enable with ImGuiConfigFlags_NavEnableGamepad. See suggested mappings in imgui.h ImGuiNavInput_ + download PNG/PSD at http://dearimgui.org/controls_sheets PROGRAMMER GUIDE ================ READ FIRST ---------- - Remember to check the wonderful Wiki (https://github.com/ocornut/imgui/wiki) - Your code creates the UI, if your code doesn't run the UI is gone! The UI can be highly dynamic, there are no construction or destruction steps, less superfluous data retention on your side, less state duplication, less state synchronization, fewer bugs. - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features. - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build. - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori). You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in Wiki. - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances. For every application frame, your UI code will be called only once. This is in contrast to e.g. Unity's implementation of an IMGUI, where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches. - Our origin is on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right. - This codebase is also optimized to yield decent performances with typical "Debug" builds settings. - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected). If you get an assert, read the messages and comments around the assert. - C++: this is a very C-ish codebase: we don't rely on C++11, we don't include any C++ headers, and ImGui:: is a namespace. - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types. See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that. However, imgui_internal.h can optionally exp
