[QUESTION] - How to handle ctrl+c on raw mode?

[stevefan1999-personal]

I tried adding it to any components, which here I used the Label component from the example, but it doesn't work so far:

impl Component<Msg, NoUserEvent> for Label {
    fn on(&mut self, ev: Event<NoUserEvent>) -> Option<Msg> {
        match ev {
            Event::Keyboard(KeyEvent {
                code: Key::Char('c'),
                modifiers: KeyModifiers::CONTROL,
            })
            | Event::Keyboard(KeyEvent {
                code: Key::Esc,
                modifiers: KeyModifiers::NONE,
            }) => Some(Msg::AppClose),

            _ => None,
        }
    }
}

I tried to handle this by using an external ctrl+c handler from tokio, then I sent an empty tuple using a MPSC channel, and did blocking receive on the TUI thread for each loop, then send AppClose event over there. But it didn't work as well.

Does the esc key work? Did you give focus to the label?

Just for the record, to terminate the application, it is better to use subscriptions to a phantom component, in order to always listen for that event, beside of what component has the focus.

You can view an example here:

#[derive(Default, MockComponent)]
pub struct GlobalListener {
    component: Phantom,
}

impl Component<Msg, NoUserEvent> for GlobalListener {
    fn on(&mut self, ev: Event<NoUserEvent>) -> Option<Msg> {
        match ev {
            Event::Keyboard(KeyEvent {
                code: Key::Esc | Key::Function(10),
                ..
            }) => Some(Msg::Ui(UiMsg::ShowQuitPopup)),
            Event::Keyboard(KeyEvent {
                code: Key::Char('c'),
                modifiers: KeyModifiers::CONTROL,
            }) => Some(Msg::Form(FormMsg::EnterSetup)),
            Event::WindowResize(_, _) => Some(Msg::Ui(UiMsg::WindowResized)),
            _ => None,
        }
    }
}

            self
            .app
            .mount(
                Id::GlobalListener,
                Box::new(components::GlobalListener::default()),
                vec![
                    Sub::new(
                        SubEventClause::Keyboard(KeyEvent {
                            code: Key::Esc,
                            modifiers: KeyModifiers::NONE,
                        }),
                        Self::no_popup_mounted_clause(),
                    ),
                    Sub::new(
                        SubEventClause::Keyboard(KeyEvent {
                            code: Key::Function(10),
                            modifiers: KeyModifiers::NONE,
                        }),
                        Self::no_popup_mounted_clause(),
                    ),
                    Sub::new(
                        SubEventClause::Keyboard(KeyEvent {
                            code: Key::Char('c'),
                            modifiers: KeyModifiers::CONTROL,
                        }),
                        Self::no_popup_mounted_clause(),
                    ),
                    Sub::new(SubEventClause::WindowResize, SubClause::Always)
                ]
            )
