glasskit

Native Windows UI with a glass look, in Rust: a tray icon and menu, a frosted-glass popup, themed dialogs, and helpers for tray apps.

• Event loop: one loop for all windows of the thread. It sleeps until a menu command, the end of a popup, a change in a dialog, a deadline, or an unlock of the session.
• Tray: an icon in the notification area with a menu of your own commands.
• Popup: a frosted-glass popup with a question and choice buttons. It fades in without taking the keyboard focus, can show whether a choice was correct, and can dismiss itself after a countdown.
• Dialog: a small modal window of standard controls with typed handles, in the same colors.
• Helpers: start with Windows, single instance, efficiency mode, and whether the user can see a popup now.

All windows follow the Windows light or dark mode and the display scale.

Example

use glasskit::Ui;
use glasskit::events::{Event, EventLoop};
use glasskit::placement::Placement;
use glasskit::popup::{ChoicePopup, Prompt};
use glasskit::tray::{Icon, MenuItem, Tray};

#[derive(Clone)]
enum Command {
    Ask,
}

fn main() -> glasskit::Result<()> {
    let ui = Ui::new()?;
    let mut events = EventLoop::new(&ui)?;
    let size = Icon::tray_size();
    let icon = Icon::from_argb(size, vec![0xFF2E_86DE; (size * size) as usize])?;
    let mut tray = Tray::new(&events, "Hello", &icon)?;
    tray.set_menu(&[
        MenuItem::command(Command::Ask, "Ask"),
        MenuItem::Quit("Quit".into()),
    ]);
    let mut popup = ChoicePopup::new(&ui, Placement::default())?;
    loop {
        match events.next(None)? {
            Event::Command(Command::Ask) if !popup.is_showing() => {
                popup.show(&Prompt::new("Is the tray working?", ["Yes", "No"]))?;
            }
            Event::Popup(_) => {
                popup.take_reply();
            }
            Event::Quit => return Ok(()),
            _ => {}
        }
    }
}

A longer example, a small quiz app, is in examples/quiz.rs: cargo run -p glasskit --example quiz.
