Import

use gpui_component::ContextModal;

Usage

Setup application root view for display of modals

You need to set up your application's root view to render the modal layer. This is typically done in your main application struct's render method.

The Root::render_modal_layer function handles rendering any active modals on top of your app content.

use gpui_component::TitleBar;

struct MyApp {
    view: AnyView,
}

impl Render for MyApp {
    fn render(&mut self, window: &mut Window, cx: &mut Context<Self>) -> impl IntoElement {
        let modal_layer = Root::render_modal_layer(window, cx);

        div()
            .size_full()
            .child(
                v_flex()
                    .size_full()
                    .child(TitleBar::new())
                    .child(div().flex_1().overflow_hidden().child(self.view.clone())),
            )
            // Render the modal layer on top of the app content
            .children(modal_layer)
    }
}

window.open_modal(cx, |modal, _, _| {
    modal
        .title("Welcome")
        .child("This is a modal dialog.")
})

let input = cx.new(|cx| InputState::new(window, cx));

window.open_modal(cx, |modal, _, _| {
    modal

        .child(
            v_flex()
                .gap_3()
                .child("Please enter your details:")
                .child(TextInput::new(&input))
        )
        .footer(|_, _, _, _| {
            vec![
                Button::new("ok")
                    .primary()
                    .label("Submit")
                    .on_click(|_, window, cx| {
                        window.close_modal(cx);
                    }),
                Button::new("cancel")
                    .label("Cancel")
                    .on_click(|_, window, cx| {
                        window.close_modal(cx);

            window.push_notification("Item deleted", cx);
            true // Return true to close modal
        })
        .on_cancel(|_, window, cx| {
