Example

#![windows_subsystem = "windows"]

use fui_app::*;
use fui_controls::*;
use fui_core::*;
use fui_macros::ui;

use std::cell::RefCell;
use std::rc::Rc;

use typed_builder::TypedBuilder;
use typemap::TypeMap;
use winit::window::WindowBuilder;

struct MainViewModel {
    pub counter: Property<i32>,
}

impl MainViewModel {
    pub fn new() -> Rc<Self> {
        Rc::new(MainViewModel {
            counter: Property::new(0),
        })
    }

    pub fn increase(self: &Rc<Self>) {
        self.counter.change(|c| c + 1);
    }
}

impl ViewModel for MainViewModel {
    fn create_view(self: &Rc<Self>) -> Rc<RefCell<dyn ControlObject>> {
        ui!(
            Horizontal {
                Text { text: (&self.counter, |counter| format!("Counter {}", counter)) },
                Button {
                    clicked: Callback::new_rc(self, |vm, _| vm.increase()),
                    Text { text: "Increase" }
                },
            }
        )
    }
}

fn main() -> anyhow::Result<()> {
    let mut app = Application::new("Example: button").unwrap();

    app.add_window(
        WindowBuilder::new().with_title("Example: button"),
        MainViewModel::new(),
    )?;

    app.run();

    Ok(())
}
