Dialog component for creating dialogs, confirmations, and alerts. Supports overlay, keyboard shortcuts, and various customizations.

Import

use gpui_component::dialog::DialogButtonProps;
use gpui_component::WindowExt;

Usage

Setup application root view for display of dialogs

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

The Root::render_dialog_layer function handles rendering any active dialogs 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 dialog_layer = Root::render_dialog_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 dialog layer on top of the app content
            .children(dialog_layer)
    }
}

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

Form Dialog

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

window.open_dialog(cx, |dialog, _, _| {
    dialog
        .title("User Information")
        .child(
            v_flex()
                .gap_3()
                .child("Please enter your details:")
                .child(Input::new(&input))
        )
        .footer(|_, _, _, _| {
            vec![
                Button::new("ok")
                    .primary()
                    .label("Submit")
                    .on_click(|_, window, cx| {
                        window.close_dialog(cx);
                    }),
                Button::new("cancel")
                    .label("Cancel")
                    .on_click(|_, window, cx| {
                        window.close_dialog(cx);

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

        .button_props(
            DialogButtonProps::default()
                .cancel_text("Later")
                .cancel_variant(ButtonVariant::Secondary)
                .ok_text("Restart Now")
                .ok_variant(ButtonVariant::Danger)
        )
        .on_ok(|_, window, cx| {

                    .size_6()
                    .text_color(cx.theme().warning))
                .child("This action cannot be undone.")
        )
})

        .title("Custom Dialog")
        .overlay(true)              // Show overlay (default: true)
        .overlay_closable(true)     // Click overlay to close (default: true)
        .keyboard(true)             // ESC to close (default: true)
        .close_button(false)        // Show close button (default: true)
        .child("Dialog content")
})

                            dialog
                                .title("Second Dialog")

Close Dialog Programmatically

The close_dialog method can be used to close the active dialog from anywhere within the window context.

// Close top level active dialog.
window.close_dialog(cx);

// Close and perform action
Button::new("submit")
    .primary()
    .label("Submit")
    .on_click(|_, window, cx| {
        // Do something
        window.close_dialog(cx);
    })

            dialog
