using System;
using Gtk;
public class DemoEntryCompletion : Window
{
static void Main ()
{
Application.Init ();
new DemoEntryCompletion ();
Application.Run ();
}
public DemoEntryCompletion () : base ("Demo Entry Completion")
{
this.BorderWidth = 10;
this.Resizable = false;
VBox vbox = new VBox ();
Label label = new Label ("Completion demo, try writing <b>total</b> or </b>gnome</b> for example.");
label.UseMarkup = true;
vbox.PackStart (label, false, true, 0);
Entry entry = new Entry ();
entry.Completion = new EntryCompletion ();
entry.Completion.Model = CreateCompletionModel ();
entry.Completion.TextColumn = 0;
vbox.PackStart (entry, false, true, 0);
this.Add (vbox);
this.ShowAll ();
}
TreeModel CreateCompletionModel ()
{
ListStore store = new ListStore (typeof (string));
store.AppendValues ("GNOME");
store.AppendValues ("total");
store.AppendValues ("totally");
return store;
}
}
