Any chance to get cdep support ? It would make dev 's life so much easier (^_^)

Yo all, just wanted to try this out, since it looks like ImGui and I wanted to compare, but I can't even build it:

I used CMake GUI to build the project, deselected 2 DirectX checkbuttons, because it didn't find the DX SDK (Windows 10 have it already?). Well, generating .sln worked nicely then, but it missed the generation of these header files it seems.

dependencies can not be download correctly

following instructions on https://google.github.io/flatui/flatui_guide_osx.html

• ran git clone --recursive https://github.com/google/flatui.git
• ran cd flatui
• ran cmake -G Xcode .

Result:

-- FlatUI standalone: building tests and samples
-- 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 "/Users/xxxxx/dev/flatui/CMakeFiles/CMakeOutput.log".

attempts to follow the instructions re: SDL failure have borne no fruit

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?

When I try to compile FlatUI on Linux I have an issue:

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?

BR, nonew

It is extremely important to include examples of GUI use for those having the first look. Good example is ImGUI https://github.com/ocornut/imgui.

A few files in cmake/harfbuzz/CMakeLists.txt such as ${harfbuzz_dir}/src/hb-ot-shape-complex-use.cc are missing from the commit the submodule is pointing to.

I'm using the toolchain 4.9 and have that compilation issue:

actually 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?

Is being able to use FlatUI but not FPLBase a use case that FlatUI would like to support ?

I didn't find any info on iOS support.
Since this is a C++ library, my first, most probably wrong expectation, would be that it does not present a big hurdle to port it to iOS.
Is iOS support planned?

Running cmake -G'Unix Makefiles' . inside the flatui main folder in Ubuntu 14.04 causes the following error:

The source directory

    /home/yourname/flatui/dependencies/mathfu

  does not contain a CMakeLists.txt file.

All the needed libraries are installed. I've also tried to checkout the entire project again bu I had the very same issue.

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!
