Backend improvements (imgui_impl_android.h/.cpp):
- Moved JNI soft-keyboard and Unicode char polling from the example into
the backend. The application no longer needs any JNI boilerplate.
- Added clipboard support via JNI to Android ClipboardManager. (#7259)
- Added display metrics (DPI, density, refresh rate, orientation) via JNI.
Used by the example to set main_scale from actual device density instead
of hardcoded 2.0f.
- BREAKING CHANGE: ImGui_ImplAndroid_Init() now takes additional
asset_manager and native_activity parameters. See before/after in header.
Example (main.cpp):
- Removed ShowSoftKeyboardInput() and PollUnicodeChars() JNI helpers (~120 lines).
- Removed their forward declarations and per-frame calls.
- Updated Init() call to new signature.
- Use ImGui_ImplAndroid_GetDisplayMetrics() for main_scale.
- All other comments, EGL block, GetAssetData, APP_CMD cases unchanged.
MainActivity.kt: unchanged (same 3 JNI bridge methods, now called by backend).
docs/CHANGELOG.txt: Added entries for backend and example changes.
Add .github/workflows/deploy-wasm.yml that:
- Installs Emscripten SDK on ubuntu-latest
- Builds example_sdl2_opengl3 with Makefile.emscripten using -sSINGLE_FILE
(all WASM+JS embedded in a single .html file, no separate .wasm/.js)
- Uses custom shell_imgui_xl.html with loading spinner and WebGL context
loss handling
- Deploys to gh-pages/wasm/ directory via peaceiris/actions-gh-pages
The resulting live demo at turtle-pb.github.io/imgui_xl/wasm/index.html
will show the ACTUAL Dear ImGui demo window running in the browser via
WebAssembly — not a canvas simulation, but real compiled C++ ImGui.
Triggers on pushes to master that touch ImGui source files, the SDL2/
OpenGL3 backend, the example, or the shell template.
Also supports manual workflow_dispatch.
bindings/go/:
- imgui_bridge.h/.cpp: Thin C API bridge (extern C) wrapping C++ ImGui
- imgui.go: Go cgo package (CreateContext, NewFrame, Begin, Button,
SliderFloat, SliderInt, Checkbox, ColorEdit3, Text, Combo, etc.)
- go.mod: Module definition
- README.md: Full docs with usage, building, and API reference
examples/example_golang/:
- main.go: Null-mode example showing ImGui from Go
- go.mod: Module with replace directive for local bindings
- Makefile: Build/run/clean targets
Go 1.26.5 verified working on this host. CGO_ENABLED=1 required
(plus a C++ compiler like g++ for the bridge compilation).
Add a fully self-contained Pixel 8 Pro phone simulator that showcases
Pixel OS capabilities in any browser. Includes:
- Working menu bar (File, View, Tools, Help) with keyboard shortcuts
- Lock screen with live clock, notifications, fingerprint/swipe unlock
- Home screen with Material You design, Google search, weather widget
- 7 functional apps: Phone, Messages, Camera, Settings, Clock, Photos, Browser
- Quick Settings panel with 8 toggle tiles + brightness slider
- Recents app switcher
- Dark mode toggle and 6-theme color switcher
- Mouse + touch gesture support (swipe up for home, swipe down for QS)
- Bottom status bar showing demo state
All functions work — every menu item, button, toggle, and gesture
is wired to a real handler. No build step, no dependencies.
Part of imgui_xl examples.
- in Firefox, scrollbar would appear => adding overflow: hidden fixes this issue
- when the canvas has the focus, Chrome draws a very small blue outline, setting it to none fixes this issue
- This commit removes the option of using -sUSE_WEBGPU=1 from CMake and make
- Compiling with a version of Emscripten >= 4.0.10 will work the same way as it was before
- Compiling with a version of Emscripten < 4.0.10 will print an error message and abort the build (in the case of CMake)
- Since there can only be 1 implementation for the backend in the case of Emscripten, this commit cleans the code accordingly
Without tabindex, the canvas element is not focusable in the DOM, so pongasoft/emscripten-glfw's focus/blur listeners on the canvas
never fire. This means glfwSetWindowFocusCallback is never called etc.
