sessionlock binding for iced

iced-layershell provides binding for iced and sessionlock.

Session lock is the wayland protocol for lock. This protocol is supported in river, sway and etc. We use it make a beautiful lock program in twenty. You can also use it to build your sessionlock. This will become very easy to use our crate with pam crate.

The smallest example is like

use iced::widget::{Space, button, column, text, text_input};
use iced::{Alignment, Element, Event, Length, Task as Command, event};
use iced_sessionlock::actions::UnLockAction;
use iced_sessionlock::application;
use iced_sessionlock::to_session_message;

pub fn main() -> Result<(), iced_sessionlock::Error> {
    application(Counter::new, Counter::update, Counter::view)
        .subscription(Counter::subscription)
        .run()
}

struct Counter {
    value: i32,
    text: String,
}

#[to_session_message]
#[derive(Debug, Clone)]
enum Message {
    IncrementPressed,
    DecrementPressed,
    TextInput(String),
    IcedEvent(Event),
}

impl Counter {
    fn new() -> (Self, Command<Message>) {
        (
            Self {
                value: 0,
                text: "eee".to_string(),
            },
            Command::none(),
        )
    }

    fn namespace(&self) -> String {
        String::from("Counter - Iced")
    }

    fn subscription(&self) -> iced::Subscription<Message> {
        event::listen().map(Message::IcedEvent)
    }

    fn update(&mut self, message: Message) -> Command<Message> {
        match message {
            Message::IcedEvent(event) => {
                println!("hello {event:?}");
                Command::none()
            }
            Message::IncrementPressed => {
                self.value += 1;
                Command::none()
            }
            Message::DecrementPressed => {
                self.value -= 1;
                Command::none()
            }
            Message::TextInput(text) => {
                self.text = text;
                Command::none()
            }
            Message::UnLock => Command::done(message),
        }
    }

    fn view(&self, _id: iced::window::Id) -> Element<Message> {
        column![
            Space::new().height(Length::Fill),
            button("Increment").on_press(Message::IncrementPressed),
            button("Lock").on_press(Message::UnLock),
            text(self.value).size(50),
            text_input("hello", &self.text)
                .on_input(Message::TextInput)
                .padding(10),
            button("Decrement").on_press(Message::DecrementPressed),
            Space::new().height(Length::Fill),
        ]
        .padding(20)
        .align_x(Alignment::Center)
        .width(Length::Fill)
        .height(Length::Fill)
        .into()
    }
}
