<summary>A widget used to choose from a list of valid choices.</summary>
<remarks>
<para>
A <see cref="T:Gtk.OptionMenu" /> is a widget that allows the user to choose from a list of valid choices.
The <see cref="T:Gtk.OptionMenu" /> displays the selected choice.
When activated the <see cref="T:Gtk.OptionMenu" /> displays a popup <see cref="T:Gtk.Menu" /> which allows the user to make a new choice.
</para>
<para>
Using a <see cref="T:Gtk.OptionMenu" /> is simple; build a <see cref="T:Gtk.Menu" />, by calling <see cref="C:Gtk.Menu()" />, then appending <see cref="T:Gtk.MenuItem" />s to it with <see cref="M:Gtk.MenuShell.Append()" />.
Set that menu on the <see cref="T:Gtk.OptionMenu" /> with <see cref="P:Gtk.OptionMenu.Menu" />.
Set the selected <see cref="T:Gtk.MenuItem" /> with <see cref="M:Gtk.OptionMenu.SetHistory(System.UInt32)" />; connect to the event <see cref="E:Gtk.OptionMenu.Changed" />; when the <see cref="E:Gtk.OptionMenu.Changed" /> event occurs, check the new selected <see cref="T:Gtk.MenuItem" /> with <see cref="P:Gtk.OptionMenu.History" />.
</para>
</remarks>
<example>
<code language="C#">
using System;
using Gtk;
using GtkSharp;
class OptionMenuSample
{
OptionMenu opt;
static void Main ()
{
new OptionMenuSample ();
}
OptionMenuSample ()
{
Application.Init ();
Window win = new Window ("OptionMenuSample");
win.DeleteEvent += new DeleteEventHandler (OnWinDelete);
// set up the OptionMenu
opt = new OptionMenu ();
opt.Changed += new EventHandler (OnOptionChanged);
Menu m = new Menu ();
MenuItem miOne = new MenuItem ("One");
m.Append (miOne);
MenuItem miTwo = new MenuItem ("Two");
m.Append (miTwo);
MenuItem miThree = new MenuItem ("Three");
m.Append (miThree);
// add children widgets to their parents
opt.Menu = m;
win.Add (opt);
// set the OptionMenu to a value
opt.SetHistory (2);
win.ShowAll ();
Application.Run ();
}
void OnOptionChanged (object o, EventArgs args)
{
Console.WriteLine (opt.History);
}
void OnWinDelete (object o, DeleteEventArgs args)
{
Application.Quit ();
}
}
