A declarative desktop GUI framework for the Rust programming language.
- Build desktop applications which look and behave the same for Windows, Mac, and Linux.
- Write GUI code in a declarative way in pure Rust (no DSL macros).
- Views derive from application state. Change the state and the views which bind to it update automatically.
- Create flexible layouts which adapt to changes in size. Powered by morphorm.
- Take advantage of CSS with hot-reloading to fully customize the style of your application.
- Bring your application to life with animatable style properties.
- Utilize over 25 ready-made views as well as two built-in themes (light and dark) to get you started. Includes 4250+ icons, provided by Tabler Icons.
- Make you applications accessible to assistive technologies such as screen readers, powered by accesskit.
- Adapt your application to different locales, including translating text with fluent.
- Vizia leverages the GPU for fast graphical updates, powered by femtovg.
- Vizia provides an alternative baseview windowing backend for audio plugin development, for example with the nih-plug framework.
A simple counter application. Run with cargo run --example counter.
use vizia::prelude::*;
// Define some model data
#[derive(Lens)]
pub struct AppData {
count: i32,
}
// Define events to mutate the data
pub enum AppEvent {
Increment,
}
// Describe how the data is mutated in response to events
impl Model for AppData {
fn event(&mut self, _: &mut EventContext, event: &mut Event) {
event.map(|app_event, _| match app_event {
AppEvent::Increment => {
self.count += 1;
}
});
}
}
fn main() {
// Create an application
Application::new(|cx| {
// Build the model data into the tree
AppData { count: 0 }.build(cx);
// Declare views which make up the UI
HStack::new(cx, |cx| {
// Declare a button which emits an event
Button::new(cx, |cx| Label::new(cx, "Increment"))
.on_press(|cx| cx.emit(AppEvent::Increment));
// Declare a label which is bound to part of the model, updating when it changes
Label::new(cx, AppData::count).width(Pixels(50.0));
})
.child_space(Stretch(1.0)) // Apply style and layout modifiers
.col_between(Pixels(50.0));
})
.title("Counter") // Configure window properties
.inner_size((400, 100))
.run();
}
A quickstart guide for vizia is available here.
Auto-generated code documentation can be found here.
A list of examples is included in the repository.
To run an example with the winit (default) windowing backend:
cargo run --release --example name_of_exampleTo run an example with the baseview windowing backend:
cargo run --release --example name_of_example --no-default-features --features baseviewTo run an example as a web application, first ensure that the wasm32-unknown-unknown toolchain is installed:
rustup target add wasm32-unknown-unknownThen run an example with the following:
cargo run-wasm --release --example name_of_exampleNote Some examples are not compatible with the web target and will intentionally panic if run on web.
