<summary>A widget used to choose from a list of valid choices.</summary>

<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" />.
