`Clickable`

Clickable is the static builder capability shared by Button, IconButton, and Switch. It is not a cross-Entity event bus.

rust

pub trait Clickable: Sized {
    fn on_click(
        self,
        handler: impl Fn(&ClickEvent, &mut Window, &mut App) + 'static,
    ) -> Self;
    fn cursor_style(self, cursor_style: CursorStyle) -> Self;
    fn on_click_in<T: 'static>(
        self,
        cx: &Context<T>,
        handler: impl Fn(
            &mut T,
            &ClickEvent,
            &mut Window,
            &mut Context<T>,
        ) + 'static,
    ) -> Self;
}

Implementors: Button, IconButton, and Switch. on_click accepts a standard GPUI callback. on_click_in binds the host Entity through Context::listener; after that Entity is destroyed, GPUI's weak-listener behavior safely becomes a no-op. Switch can use this entry to request the backend first and update controlled checked only after success.

rust

.child(
    self.click_button("button-basic-interactive", copy.add, cx)
        .on_focus_in(cx, move |this, _, cx| {
            this.record_focus(copy.add, true, cx);
        })
        .on_blur_in(cx, move |this, _, cx| {
            this.record_focus(copy.add, false, cx);
        }),
)
.child(
    Button::new("button-basic-disabled")
        .label(copy.disabled)
        .variant(ButtonVariant::Secondary)
        .disabled(true),
)
.child(self.click_button("button-basic-default", copy.default, cx)),

Disabled components, and Button loading/progress, block activation. Component pages define exact mouse, Enter, and Space timing. ClickEvent belongs to GPUI.
