Tesserae - Spinner

Spinner

Description

The Spinner component is a visual indicator that displays an animated circle outline, suggesting that a background process is running. It is commonly used when the duration of the task is unknown, serving as an indeterminate progress indicator. The Spinner supports various sizes and allows positioning of an associated label to provide additional context (for example, "Loading...", "Saving...", etc.). It is part of the Progress group in Tesserae's UI components.

Usage

Instantiate the Spinner component using the Tesserae.UI helper methods. You can create a spinner with initial text and further customize its size and label position. The following sample demonstrates a basic usage:

spinner-sample.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using H5.Core;
using Tesserae;
using static H5.Core.dom;
using static Tesserae.UI;

namespace Tesserae.Tests
{
    internal static class App
    {
        private static void Main()
        {
            var spinner = Spinner("Loading, please wait...").Medium();
            document.body.style.overflow = "hidden";
            MountCenteredToBody(spinner);
        }
    }
}
