// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
// 2021-03-22: Vulkan: Fix mapped memory validation error when buffer sizes are not multiple of VkPhysicalDeviceLimits::nonCoherentAtomSize.

// If you use VK_DYNAMIC_STATE_VIEWPORT or VK_DYNAMIC_STATE_SCISSOR you are responsible for setting the values before rendering.
// In theory we should aim to backup/restore those values but I am not sure this is possible.

@ -117,6 +117,21 @@ Breaking Changes:
Other Changes:
- Added IsMouseTripleClicked() function. Tracking multi-click count in IO structure. (#3229) [@kudaba]
- Modals: fixed issue hovering popups inside a child inside a modal. (#4676, #4527)
- Fixed IsWindowFocused()/IsWindowHovered() issues with childs inside popups. (#4676)
- Nav: pressing PageUp/PageDown/Home/End when in Menu layer automatically moves back to Main layer.
- Nav: fixed resizing window from borders setting navigation to Menu layer.
- Nav: pressing Esc to exit a child window reactivates the Nav highlight if it was disabled by mouse.
- Nav: (with ImGuiConfigFlags_NavEnableSetMousePos): fixed absolute mouse position when using Home/End
leads to scrolling.
- Nav: (with ImGuiConfigFlags_NavEnableSetMousePos): fixed not setting mouse position when a failed
move request (e.g. already at edge) reactivate the navigation highlight.
- InputText: made double-click select word, triple-line select line. Word delimitation logic differs
slightly from the one used by CTRL+arrows. (#2244)
- Backends: Vulkan: Call vkCmdSetScissor() at the end of render with a full-viewport to reduce
likehood of issues with people using VK_DYNAMIC_STATE_SCISSOR in their app without calling
vkCmdSetScissor() explicitly every frame. (#4644)
- Misc: Fix MinGW DLL build issue (when IMGUI_API is defined). [@rokups]
- CI: Add MinGW DLL build to test suite. [@rokups]

- Math operators: if you have setup `IM_VEC2_CLASS_EXTRA` in `imconfig.h` to bind your own math types, you can use your own math types and their natural operators instead of ImVec2. ImVec2 by default doesn't export any math operators in the public API. You may use `#define IMGUI_DEFINE_MATH_OPERATORS` `#include "imgui_internal.h"` to use the internally defined math operators, but instead prefer using your own math library and set it up in `imconfig.h`.
- You can use `ImGui::GetBackgroundDrawList()` or `ImGui::GetForegroundDrawList()` to access draw lists which will be displayed behind and over every other dear imgui windows (one bg/fg drawlist per viewport). This is very convenient if you need to quickly display something on the screen that is not associated to a dear imgui window.
- You can also create your own empty window and draw inside it. Call Begin() with the NoBackground | NoDecoration | NoSavedSettings | NoInputs flags (The `ImGuiWindowFlags_NoDecoration` flag itself is a shortcut for NoTitleBar | NoResize | NoScrollbar | NoCollapse). Then you can retrieve the ImDrawList* via `GetWindowDrawList()` and draw to it in any way you like.
`- You can create your own ImDrawList instance. You'll need to initialize them with `ImGui::GetDrawListSharedData()`, or create your own instancing ImDrawListSharedData`, and then call your renderer function with your own ImDrawList or ImDrawData data.

- You may also refer to our [Continuous Integration setup](https://github.com/ocornut/imgui/tree/master/.github/workflows) for Emscripten setup.
- Depending on your configuration, in Windows you may need to run `emsdk/emsdk_env.bat` in your console to access the Emscripten command-line tools.

# How to Build
## How to Build
- You need to install Emscripten from https://emscripten.org/docs/getting_started/downloads.html, and have the environment variables set, as described in https://emscripten.org/docs/getting_started/downloads.html#installation-instructions
- Depending on your configuration, in Windows you may need to run `emsdk/emsdk_env.bat` in your console to access the Emscripten command-line tools.
- You may also refer to our [Continuous Integration setup](https://github.com/ocornut/imgui/tree/master/.github/workflows) for Emscripten setup.
- Then build using `make` while in the `example_emscripten_wgpu/` directory.
- Requires Emscripten 2.0.10 (December 2020) due to GLFW adaptations
- Requires recent Emscripten as WGPU is still a work-in-progress API.
## How to Run
To run on a local machine:
- Make sure your browse supports WGPU and it is enabled. WGPU is still WIP not enabled by default in most browser.
- `make serve` will use Python3 to spawn a local webserver, you can then browse http://localhost:8000 to access your build.
- Otherwise, generally you will need a local webserver:
- Quoting [https://emscripten.org/docs/getting_started](https://emscripten.org/docs/getting_started/Tutorial.html#generating-html):<br>
_"Unfortunately several browsers (including Chrome, Safari, and Internet Explorer) do not support file:// [XHR](https://emscripten.org/docs/site/glossary.html#term-xhr) requests, and can’t load extra files needed by the HTML (like a .wasm file, or packaged file data as mentioned lower down). For these browsers you’ll need to serve the files using a [local webserver](https://emscripten.org/docs/getting_started/FAQ.html#faq-local-webserver) and then open http://localhost:8000/hello.html."_
- Emscripten SDK has a handy `emrun` command: `emrun web/example_emscripten_opengl3.html --browser firefox` which will spawn a temporary local webserver (in Firefox). See https://emscripten.org/docs/compiling/Running-html-files-with-emrun.html for details.
- You may use Python 3 builtin webserver: `python -m http.server -d web` (this is what `make serve` uses).
- You may use Python 2 builtin webserver: `cd web && python -m SimpleHTTPServer`.
- If you are accessing the files over a network, certain browsers, such as Firefox, will restrict Gamepad API access to secure contexts only (e.g. https only).
