v1.92.700

ImGui

• Update ImGui to v1.92.7-docking

• Add CreateTextureFromRgbaData and DeleteTexture
• Add ImageAndSizeFromEncodedData and LoadImageDataFromEncodedData (decode images from in-memory buffers)

Emscripten:

• IniFolderLocation on emscripten now returns "" for CurrentFolder (and "/" for other types)

Fixes:

• Skip TearDown if already ran at exit (e.g. if it threw an exception itself)
• LoadDefaultFont_WithFontAwesomeIcons: log if icon font not found

Docs:

• Document theming usage

Internals

Full Changelog: v1.92.601...v1.92.700

v1.92.601

• Add LoadImageDataFromAsset() — decode an image from assets into CPU memory (C++ only), with configurable channel count

Warnings hunt

• Fix potential memory error in font handling (_LoadFontImpl: pass font buffer allocated with IM_ALLOC)
• Compile imgui_impl_metal.mm with -fobjc-arc (fixes ARC bridge cast warnings on macOS)
• Suppress Apple Clang -Wdeprecated-declarations warning in imgui_freetype.cpp (caused by sprintf in third-party plutosvg-ft.h)
• Update plutovg to v1.3.2 and plutosvg to v0.0.7
• Workaround plutovg file(RELATIVE_PATH) error when CMAKE_INSTALL_PREFIX is relative (scikit-build-core wheel builds)

• cmake/assets: create asset destination dirs before copy_if_different

Full Changelog: v1.92.6...v1.92.601

v1.92.6

• Update ImGui to v1.92.6-docking

New Callbacks:

• Add callback PostNewFrame
• Add ThemeChanged callback (Fixes #156)

New RunnerParams:

• Added params iniDisable & iniClearPreviousSettings
• add topMost window attribute
• FpsIdling : Add configurable vsyncToMonitor + fpsMax. This introduces a new vsyncToMonitor field in FpsIdling, allowing users to
  enable/disable synchronization with the monitor refresh rate.
• Added params to control ini file settings

// `iniDisable`: _bool, default = false_. If true, do not save or load any settings to or from an ini file.
bool iniDisable = false;
// `iniClearPreviousSettings`: _bool, default = false_. If true, delete any previous settings ini file at application startup.
bool iniClearPreviousSettings = false;

Emscripten

• add loading spinner overlay to default shell template
• use Glfw3 by default instead of Sdl2. We use pongasoft/emscripten-glfw under emscripten, which has good support for the clipboard

Fixes:

• Fix: ManualRender RunnerParams lifetime management
  Issue: pthom/imgui_bundle#417
• RaiseWindow at startup (improve SDL initial show on macOS)

Assets Handling:

• Add AddAssetsSearchPath to allow adding additional search paths for assets (e.g. to load assets from a different location, or to load additional assets without modifying the original assets folder)

v1.92.0

Version numbers are now synced between "Dear ImGui" "Hello ImGui" and "Dear ImGui Bundle".

• ImGui: Many Font related changes: this release brings many changes on the ImGui side (v1.92.0): do read the release notes for ImGui v1.92.0
  TLDR: Fonts may be rendered at any size. Glyphs are loaded and rasterized dynamically. No need to specify ranges, prebake etc.

• Removed FontDpiResponsive: this is now handled by ImGui itself

• Removed FontLoadingParams.glyphRanges, since ranges are not needed anymore by ImGui

Contributions

• Add utility function void ChangeWindowFullMonitorWorkArea() like void… by @Robxley in #130

• support imgui 1.91.9 breaking changes by @toge in #142

New Contributors

• @Robxley made their first contribution in #130
• @toge made their first contribution in #142

• Runner: call TearDown on Setup for Python (to make it possible to recover from exceptions in notebook)
• MakeWindowSizeRelativeTo96Ppi_IfRequired: call EnsureWindowFitsThisMonitor
• update example_integration (Add CMake example / GNU Install)
• Add cmake option HELLOIMGUI_USE_EXTERNAL_JSON (to provide nlohmann json yourself)

v1.5.2

• Updated imgui to v1.90.9
• Small fixes

Full Changelog: v1.5.0...v1.5.2

v1.5.1

Changes

• Improved rendering on Windows (via antialiasing)
• Add IniFolderType.AbsolutePath
• Polish themes
• Add callback PostRenderDockableWindows
• Added optional hello_imgui.ini file,
  as a way to do advanced configuration for Dpi and OpenGL rendering options
• Add PushTweakedTheme / PopTweakedTheme (different ImGui windows can use a different theme. See demo docking)
• Add DpiAwareParams: see doc
• Add HelloImGui::ImageAndSizeFromAsset see doc
• callbacks.LoadAdditionalFonts can be modified and reused during execution
• add null backend (see https://pthom.github.io/hello_imgui/book/doc_params.html#backend-selection)
• Add optional OpenGlOptions
• Add widgets InputTextResizable + WidgetWithResizeHandle: see doc
• Add HelloImGui::LoadDpiResponsiveFont: see doc

Add FontAwesome options with support for FontAwesome 4 and FontAwesome 6:

Breaking change: you need to include manually the icons: #include "hello_imgui/icons_font_awesome_4.h"
The default icon font is FontAwesome 4 (for backward compatibility), but v6 includes many more icons

In order to select Font Awesome 6, you need to set the following in your runnerParams:

 runnerParams.runnerCallbacks.defaultIconFont = hello_imgui::IconFont::FontAwesome6;

and then include:

#include "hello_imgui/icons_font_awesome_6.h"
