<summary>A widget that creates a signal when clicked on.</summary>
<remarks>
<para>
The <see cref="T:Gtk.Button" /> widget is generally used to attach to a function that is called when the button is pressed.
The <see cref="T:Gtk.Button" /> widget can hold any valid child widget.
That is, it can hold most any other standard <see cref="T:Gtk.Widget" />. The most commonly used child is the <see cref="T:Gtk.Label" />.
</para>
<example>
<code lang="C#">
using Gtk;
using System;
public class ButtonApp {
public static int Main (string[] args)
{
Application.Init ();
Window win = new Window ("Button Tester");
win.SetDefaultSize (200, 150);
win.DeleteEvent += new DeleteEventHandler (Window_Delete);
Button btn = new Button ("Click Me");
btn.Clicked += new EventHandler (btn_click);
win.Add (btn);
win.ShowAll ();
Application.Run ();
return 0;
}
static void btn_click (object obj, EventArgs args)
{
Console.WriteLine ("Button Clicked");
}
static void Window_Delete (object obj, DeleteEventArgs args)
{
Application.Quit ();
args.RetVal = true;
}
