Overview

FlatUI Version 1.1.0 {#flatui_readme}

Welcome to FlatUI!

FlatUI is a immediate mode C++ GUI library for games and graphical applications. Go to our landing page to browse our documentation.

FlatUI aims to be a simple, efficient and easy to use way to add menus, HUDs and any kind of other UI to your game or graphical application, and provide unicode & i18n aware font-rendering. FlatUI can be built for many different systems (Android, Windows, OS X, Linux), see docs/html/index.html.

FlatUI integrates with our other game development libraries, primarily FPLBase.

Discuss FlatUI with other developers and users on the FlatUI Google Group. File issues on the FlatUI Issues Tracker or post your questions to stackoverflow.com with a mention of flatui.

Important: FlatUI uses submodules to reference other components it depends upon so download the source using:

   git clone --recursive https://github.com/google/flatui.git

Changes: Please see the release notes for a list of changes.

For applications on Google Play that integrate this tool, usage is tracked. This tracking is done automatically using the embedded version string (FlatUiVersion), and helps us continue to optimize it. Aside from consuming a few extra bytes in your application binary, it shouldn't affect your application at all. We use this information to let us know if FlatUI is useful and if we should continue to invest in it. Since this is open source, you are free to remove the version string but we would appreciate if you would leave it in.

    Compilation problem on Ubuntu

    CMake Error at cmake/freetype/CMakeLists.txt:70 (add_library): Cannot find source file: flatui/dependencies/flatui/src/libpng_to_stbimage/pngshim.cpp

    actually pngshim.cpp is in flatui/src/libpng_to_stbimage/pngshim.cpp so the CMakeLists.txt should be changed from ${dependencies_flatui_dir}/src/libpng_to_stbimage/pngshim.cpp to ${CMAKE_SOURCE_DIR}/src/libpng_to_stbimage/pngshim.cpp

    motive doesn't appear in dependencies, despite having cloned with --recursive and cmake fails because it cannot find it. I have download motive from https://github.com/google/motive and placed in dependencies.

    At this point cmake complete successful.

    I had to remove -Werror flag because both motive don't compile. The first because of the loc 200 and 206 in matrix_processor.cpp That trigger the warning strict-aliasing.

    Compiling sample fails because this command at line 262 of main CMakeLists.txt is wrong: COMMAND ${CMAKE_COMMAND} -E copy ${dependencies_flatui_dir}/sample/serialization/first_menu.json ${flatui_assets_dir}/serialization COMMAND ${CMAKE_COMMAND} -E copy ${dependencies_flatui_dir}/sample/serialization/second_menu.json ${flatui_assets_dir}/serialization)

    Should be COMMAND ${CMAKE_COMMAND} -E copy ${CMAKE_SOURCE_DIR}/sample/serialization/first_menu.json ${flatui_assets_dir}/serialization COMMAND ${CMAKE_COMMAND} -E copy ${CMAKE_SOURCE_DIR}/sample/serialization/second_menu.json ${flatui_assets_dir}/serialization)

    Once compiled I tryed to run any samples, but nothing is displayed and to kill the application I have to kill it with -9.

    Any Ideas of what I am doing wrong?

  • Any plans for i18n text support?

    Any plans for i18n text support?

    From a quick glance I see that text shaping has the following defaults with HarfBuzz:

    hb_buffer_set_direction(harfbuzz_buf_, HB_DIRECTION_LTR);
    hb_buffer_set_script(harfbuzz_buf_, HB_SCRIPT_LATIN);
    hb_buffer_set_language(harfbuzz_buf_, hb_language_from_string(text, length));
    

    There's a TODO to make these configurable but are there any plans for more robust i18n support such as BiDi, script detection etc?

  • SDL in-tree build error in Windows

    SDL in-tree build error in Windows

    Hello, Sir I met a build issue when use CMake(version 3.6.2) in Windows, (same result for CMake CMakeLists.txt command)

    D:\work\flatui>cmake -G "Visual Studio 14 2015" -- FlatUI standalone: building tests and sample -- FPLBase library: not building samples CMake Error at dependencies/sdl/CMakeLists.txt:2 (message): Prevented in-tree built. Please create a build directory outside of the SDL source code and call cmake from there

    -- Configuring incomplete, errors occurred! See also "D:/work/flatui/CMakeFiles/CMakeOutput.log".

    Seems that it is a bug in SDL CMakeLists.txt that prevents SDL from being built out-of-tree if the calling project is being built in-tree. Here is script in SDL CMakeLists.txt if(${CMAKE_SOURCE_DIR} STREQUAL ${CMAKE_BINARY_DIR}) message(FATAL_ERROR "Prevented in-tree built. Please create a build directory outside of the SDL source code and call cmake from there") endif()

    Do you guys know how to fix it?

  • How is the documentation generated ?

    How is the documentation generated ?

    Hi,

    This is not an issue and maybe off-the-topic. While I am learning FlatUI, the documentation ( here: http://google.github.io/flatui) is nice and clean. I wonder how I could generate the same style documentation for my own projects.

    I checked the docs folder, it's using doxygen and a python module named 'docs'. I couldn't find this package on the internet. Could anybody tell me where I can find it, or is it an internal module which is not open sourced yet ?

    Thanks!

Releases(1.1.0)
  • 1.1.0(Feb 24, 2017)

    The 1.1.0 release of FlatUI significantly expands the functionality of the FontManger class. Renderable text can now be created with hyphenation, elipses, emojis, various text alignments, right-to-left layouts, line height and kerning scaling, and variable font sizes, colors, and typefaces.

    The higher-level GUI features have also been greatly expanded, including animation and serialization support, and rendering to a flat plane in 3D space. See the fun CorgUI sample for a demonstration of the animation support, in particular.

    FlatUI new features:

    • Add animation support for all GUI properties (e.g. size, position, color)
    • Add responsive and stable procedural animation for ease-in-ease-out motion and spring motion
    • Provide CorgUI animation demo to showcase new animation
    • Add serialization support to author GUIs in data
    • Add 3D UI functionality, and a sample to demonstrate it
    • Add basic sprite support

    FontManager new features:

    • Add hyphenation support
    • Add system font support
    • Add an ellipsis support
    • Add emoji support
    • Add text alignment support
    • Add right-to-left script layout support
    • Add a line height scaling and a kerning scaling
    • Add support for a handful of HTML tags such as size, color, and font

    FontManager improvements:

    • Add reference counting to FontData and FontBuffer
    • Add thread safety to FontBuffer generation
    • Allow mmap for font files. Significantly improves performance when glyph access is sparce
    • Support Freetype version 2.6 and above

This is a minimal state immediate mode graphical user interface toolkit written in ANSI C and licensed under public domain. It was designed as a simple embeddable user interface for application and does not have any dependencies, a default render backend or OS window and input handling but instead provides a very modular library approach by using simple input state for input and draw commands describing primitive shapes as output.
