Alert

A versatile alert component for displaying important messages to users. Supports multiple variants (info, success, warning, error), custom icons, optional titles, closable functionality, and banner mode. Perfect for notifications, status messages, and user feedback.

#Import

use gpui_kit::component::alert::Alert;

#Usage

#Basic Alert

Alert::new("alert-id", "This is a basic alert message.")

#Alert with Title

Alert::new("alert-with-title", "Your changes have been saved successfully.")
    .title("Success!")

#Alert Variants

// Info alert (blue)
Alert::info("info-alert", "This is an informational message.")
    .title("Information")

// Success alert (green)
Alert::success("success-alert", "Your operation completed successfully.")
    .title("Success!")

    .title("Warning")

    .title("Error")

#Alert Sizes

use gpui_kit::component::{alert::Alert, Sizable as _};

Alert::info("alert", "Message content")
    .xsmall()
    .title("XSmall Alert")
Alert::info("alert", "Message content")
    .small()
    .title("Small Alert")

Alert::info("alert", "Message content")
    .title("Medium Alert")

Alert::info("alert", "Message content")
    .large()
    .title("Large Alert")

#Closable Alerts

When you add an on_close handler, a close button appears on the alert:

Alert::info("closable-alert", "This alert can be dismissed.")
    .title("Dismissible")
    .on_close(|_event, _window, _cx| {
        println!("Alert was closed");
        // Handle alert dismissal
    })

#Banner Mode

Banner alerts take full width and don’t display titles:

Alert::info("banner-alert", "This is a banner alert that spans the full width.")
    .banner()

Alert::success("banner-success", "Operation completed successfully!")
    .banner()

Alert::warning("banner-warning", "System maintenance scheduled for tonight.")
    .banner()

Alert::error("banner-error", "Service temporarily unavailable.")
    .banner()

#Custom Icons

use gpui_kit::component::IconName;

Alert::new("custom-icon", "Meeting scheduled for tomorrow at 3 PM.")
    .title("Calendar Reminder")
    .icon(IconName::Calendar)

#With Markdown Content

We can use TextView to render formatted (Markdown or HTML) text within the alert, for displaying lists, bold text, links, etc.

use gpui_kit::component::text::markdown;

Alert::error(
    "error-with-markdown",
    markdown(
        "Please verify your billing information and try again.\n\
        - Check your card details\n\
        - Ensure sufficient funds\n\
        - Verify billing address"
    ),
)
.title("Payment Failed")

#Conditional Visibility

Alert::info("conditional-alert", "This alert may be hidden.")
    .title("Conditional")
    .visible(should_show_alert) // boolean condition
