Struct App 

pub struct App<B: Backend> {
    engine: Rc<Engine<Interpreter, B>>,
}

A running app: its state, its windows, and what each widget shows.

Fields

engine: Rc<Engine<Interpreter, B>>

Implementations

impl<B: Backend> App<B>

pub fn start( program: Program, ui: Ui<B>, on_error: ErrorHandler, ) -> Result<Self, RuntimeError>

Sets up state and shows every window.

Errors

When evaluating a starting value or building the first UI fails.

Panics

When program has errors; run only programs the checker accepted.

pub fn reload(&self, program: Program) -> Result<Self, RuntimeError>

Starts program in this app’s windows, in place of this app. Each state it still declares with the same name and type keeps its value; the others start over.

Errors

When evaluating a starting value or building the new UI fails. Nothing has changed then, and this app keeps running.

Panics

When program has errors; run only programs the checker accepted.

pub fn run(&self)

Runs the event loop until the app quits.
