MUI - A Cross-Platform UI Library for V & C

MUI Demo

Supports Windows, Linux, Android 1 & Web 2 (Experimental). Not tested on MacOS 3 .

1: System themes & map widget not working on Android now. If you interested with compiling for android, look here

2: With Emscripten. System themes & map widget not working now. If you interested with compiling for web, look here

3: All critical processes (like Widget drawing, click handling etc.) should work on MacOS. But themes and screen reader won't work, and could be include MacOS-only bug.

Example

import mui as m

fn increase_count(event_details m.EventDetails,mut app &m.Window, app_data voidptr){
    unsafe{   app.get_object_by_id("count")[0]["text"].str=(app.get_object_by_id("count")[0]["text"].str.int()+1).str()   }
}

mut app:=m.create(m.WindowConfig{ title:"Counter - MUI Example", height:100, width:400 })

app.label(m.Widget{ id:"count", x:"5%x", y:"5%y", width:"45%x", height:"90%y" text:"0" })
app.button(m.Widget{ id:"count_button", x:"# 5%x", y:"5%y", width:"45%x", height:"90%y", text:"Count", onclick:increase_count })

app.run()

You can find more examples in ./examples/ folder. Also you can visit Gallery that lists applications screenshots uses MUI.

You can test MUI easily from here .

Installation

To install, run v install https://github.com/malisipi/mui

To remove, run v remove malisipi.mui

Compile-Time Flags

Flags Description
-d show_fps Show FPS of the window
-d no_emoji Disable emoji support and font embedding
-d emscripten Compile for emscripten (use with -os wasm32-emscripten )
-d dont_clip For debugging purposes, it disables clipping the widgets area. (Not recommend)
-d power_save Enables power save mode. It's recommend if your application require more resource or you're running the application on low-hardware computer. Some drawing lags would be appeared with the flag, please report them.
-d support_japanese_input Support basic japanese input

Compile for android

  • You need to use V Android Bootstrapper to compile for Android.
  • Tinyfiledialogs won't work on Android, but you can use built-in dialogs.
  • If you want to working keyboard, you need patch the sokol library that placed into v/thirdparty. You can found the patch file from ./patches .

Compile with emscripten

How to compile demo.v with emscripten:

[~/.vmodules/malisipi/mui/examples]$ v -d emscripten -d no_emoji -gc none -os wasm32-emscripten demo.v -o emscripten_.c

[~/.vmodules/malisipi/mui/examples]$ cat emscripten_.c | sed 's/waitpid(p->pid, &cstatus, 0);/-1;/g' | sed 's/waitpid(p->pid, &cstatus, WNOHANG);/-1;/g' | sed 's/wait(0);/-1;/g' &> emscripten.c

[path/to/dir/v]$ emcc -fPIC -Wimplicit-function-declaration -w  thirdparty/stb_image/stbi.c -I/usr/include/gc/   -Ithirdparty/stb_image -Ithirdparty/fontstash -Ithirdparty/sokol -Ithirdparty/sokol/util    -DSOKOL_GLES2 -DSOKOL_NO_ENTRY   -DNDEBUG -O3   -s ERROR_ON_UNDEFINED_SYMBOLS=0 -s ALLOW_MEMORY_GROWTH -s MODULARIZE -s ASSERTIONS=1 ~/.vmodules/malisipi/mui/examples/emscripten.c -o ~/.vmodules/malisipi/mui/examples/app.js --embed-file ~/.vmodules/malisipi/mui/assets/noto.ttf@/noto.ttf --embed-file ~/.vmodules/malisipi/mui/examples/[email protected]

How to Compile Programs that use malisipi.mui.webview?

  • You must to compile webview.o for one time before starting to building your applications.

  • For Windows

    • Requirenments:
    • %USERPROFILE%\.vmodules\malisipi\mui\webview> build_webview_for_windows.cmd
    • X:\path\to\example> copy "%USERPROFILE%\.vmodules\malisipi\mui\webview\webview2\runtimes\win- <win_arch> \native\WebView2Loader.dll" "X:\path\to\example"
    • X:\path\to\example> v -cc gcc example.v

  • For Linux

    • Requirenments:
      • GCC
      • libgtk-3-dev and libwebkit2gtk-4.0-dev package (on Debian-based systems)
    • [~/.vmodules/malisipi/mui/webview/]$ ./build_webview_for_linux.sh
    • You're ready to go!

Known Bugs

For Windows;

  • MSVC and TCC (without full-winapi, look below) not works. I strongly suggest GCC to compile your programs. v -cc gcc ...

If you have a problem/question or feature request about MUI, you can create a issue.

FAQ

How to use TCC on Windows
  • If you're using webview sub-module, TCC never works. Also some functions will be ignored with TCC. But you can still use TCC for Windows to compile faster.
  • You need full winapi for TCC. winapi-full-for-0.9.27.zip at download-mirror.savannah.gnu.org Download it and extract.
  • Move path\to\winapi-full-for-0.9.27\include\winapi to C:\winapi .
  • v -cc tcc run example.v
  • And it's works like a charm.
MUI is freezing with blank window and crashing with `gg error: WGL: ARB_create_context_profile required!` error (For Windows OS)

Probably, it's a issue about your drivers. You will need to ensure that you have downloaded and installed a recent driver for your graphics hardware. If your system does not contain a GPU, or the GPU vendor delivers graphics drivers providing OpenGL support that's so old as to be useless to you, you might want to consider installing the Mesa3D OpenGL library on your system.

Installing Mesa3D on Windows

Also you can download pre-built library from here

MUI not working with old-V versions

V is still beta and MUI require to break support of V's old versions to supporting latest.

  • Update V version

or

  • If you need specific V edition, look up commit history and use a commit that released with similar times.
What is operating system of test devices?
  • Windows 11
  • Arch Linux
  • Android 12
  • Windows 7/10 (Sometimes)
  • Wine 8.x (Sometimes)
Can I have tray library for MUI?

VTray library is created for this goal. So we don't require an built-in tray library for MUI. If you see any issue about MUI interoperability with this library, please report it to fix it.

Suggestions

  • You should run processes that required more time than 0.2s as concurrent. If you don't, app couldn't response until finish processes.
    • Also dialogs (specially, built-in dialogs) must to be runned concurrent as different functions than main threads. If don't, app never response.
    //Don't (App never response when call the function)
fn run_dialog(event_details m.EventDetails,mut app &m.Window, app_data voidptr){
    app.create_dialog(m.Modal{typ:"messagebox",message:"Hello, "+app.wait_and_get_answer(),title:"Hi!"})
    print(app.wait_and_get_answer())
}

//Do
fn do_another_process(mut app &m.Window){
    app.create_dialog(m.Modal{typ:"messagebox",message:"Hello, "+app.wait_and_get_answer(),title:"Hi!"})
    print(app.wait_and_get_answer())
}

fn run_dialog(event_details m.EventDetails,mut app &m.Window, app_data voidptr){
    go do_another_process(mut app)
}
