    <summary>Retrieve an integer or floating-point number from the user.</summary>
    <remarks>
      <para>A SpinButton is an ideal way to allow the user to enter a numeric value. Rather than having to directly type a number into an <see cref="T:Gtk.Entry" />, a SpinButton allows the user to click on one of two arrows to increment or decrement the displayed value. A value can still be typed in, with the added benefit that it can be checked to ensure it is within a given range.</para>
      <para>To precisely configure a SpinButton, an <see cref="T:Gtk.Adjustment" /> is used. Though it is not mandatory, its use allows fine control over the 'spinning' properties of the SpinButton.</para>
      <para>A SpinButton is typically created by setting up an <see cref="T:Gtk.Adjustment" /> and passing that to the SpinButton's constructor. The value entered by a user can then be retrieved using either the <see cref="P:Gtk.SpinButton.Value" /> property or the <see cref="P:Gtk.SpinButton.ValueAsInt" /> property.</para>
      <para>The following demonstrates how to get an integer from a SpinButton:
    <example>
          <code lang="C#">

// Creates a window with a spin button
public void CreateSpinButton() 
{
    Window window = new Window();
    window.BorderWidth = 5;
    // Create a spin button for percentage values.
    SpinButton spinner = new SpinButton(0f, 100f, 1f);
    spinner.ValueChanged += new EventHandler(OutputValue);
    window.Add(spinner);
    window.ShowAll();
}

// Handles ValueChanged events and writes to the console
private void OutputValue(object source, System.EventArgs args)
{
    SpinButton spinner = source as SpinButton;
    System.Console.WriteLine("Current value is: " + spinner.ValueAsInt);
}

    </code>
