zero-ui

Zero-Ui is the pure Rust UI framework with batteries included it provides all that you need to create beautiful, fast and responsive multi-platform apps. Ready made highly customizable widgets, automatic focus and accessibility management, responsive layout, data binding, easy localization and async tasks.

Usage

First add this to your Cargo.toml:

[dependencies]
zero-ui = { version = "0.1", features = ["view_prebuilt"] }

Then create your first window:

use zero_ui::prelude::*;

fn main() {
    zero_ui::view_process::prebuilt::init();
    APP.defaults().run_window(async {
        let size = var(layout::Size::new(800, 600));
        Window! {
            title = size.map(|s| formatx!("Button Example - {s}"));
            size;
            child_align = Align::CENTER;
            child = Button! {
                on_click = hn!(|_| {
                    println!("Button clicked!");
                });
                text::font_size = 28;
                child = Text!("Click Me!");
            }
        }
    })
}

See the API docs for more details.

Cargo Features

Zero-Ui provides the following features which can be enabled in your Cargo.toml file:

• view — Include the default view-process implementation.
• view_prebuilt — Include the default view-process implementation as an embedded precompiled binary.
• inspector — Instrument each property and widget instance with inspector nodes and extend windows to be inspected on Ctrl+Shift+I.
• trace_widget — Instrument every widget outer-most node to trace UI methods.
• trace_wgt_item — Instrument every property and intrinsic node to trace UI methods.
• deadlock_detection — Spawns a thread on app creation that checks and prints parking_lot deadlocks.
• http — Enables HTTP tasks, images download.
• test_util — Test utilities.
• multi_app — Allows multiple app instances per-process, one app per thread at a time. The LocalContext tracks what app is currently running in each thread and app_local! statics switch to the value of each app depending on the current thread.
• hyphenation_embed_all — Embed hyphenation dictionaries for all supported languages. If enabled some 2.8MB of data is embedded, you can provide an alternative dictionary source using the Hyphenation::dictionary_source method.
• dyn_node — Use more dynamic dispatch at the node level by enabling UiNode::cfg_boxed to box.
• dyn_app_extension — Use dynamic dispatch at the app-extension level.
• dyn_closure — Box closures at opportune places, such as Var::map, reducing the number of monomorphised types.
• toml — Enable TOML configs.
• ron — Enable RON configs.
• yaml — Enable YAML configs.
• material_icons — Include all Material Icons icon sets, each icon set embeds some 300KB of data.
• material_icons_outlined Include Material Icons Outlined icon set. If enabled some icons of this set are used for some of the commands.
• material_icons_filled Include Material Icons Filled icon set.
• material_icons_rounded Include Material Icons Rounded icon set.
• material_icons_sharp Include Material Icons Sharp icon set.

These features are enabled by default:

• debug_default — Enable the dyn_* and inspector features for debug builds only.
• ipc — Enables pre-build views and connecting to views running in another process.
• view_software — Enables software renderer fallback in the default view-process ("view").

Requirements

On Windows:

• To build with "view" and "view_software" feature:
  • Env vars CC and CXX must be set to "clang-cl".
  • You can install clang using the Visual Studio installer or by installing LLVM directly.

on Linux:

• Packages need to build:

  • pkg-config
  • libfontconfig1-dev

• Packages need to build with "http" feature:

  • libssl-dev

cargo do

There is a built-in task runner for managing this project, run cargo do help or ./do help for details.

The task runner is implemented as a Rust crate in tools/do-tasks and an alias in .cargo/config.toml, it builds the tool silently in the first run, after it should run without noticeable delay.

Shell script to run do are also provided:

• cmd.exe: do help.
• PowerShell: ./do.ps1 help.
• Bash: /.do help.

cargo do install

The task runner depends on multiple cargo commands, you can run cargo do install to see a list of all required commands and run cargo do install --accept to run the installation commands.

VSCode & Rust Analyzer

Some workspace settings are included in the repository, in particular, rust-analyzer "checkOnSave" and runnables are redirected to the do tool.
